Description

Technical Field

[0001] This application relates to the field of monitoring technology, and more specifically, to a control method, apparatus, storage medium, and electronic device for a monitoring device. Background Technology

[0002] AOV (Always On Video) mode is a low-power operating state designed for PTZ cameras to achieve ultra-long battery life. In this mode, the camera captures images at a low frame rate interval and temporarily stores the image data in an internal buffer instead of immediately writing it to power-intensive external storage (such as an SD card). Only when the buffer is full or a predetermined time interval is reached will the system wake up the main control unit to perform data transfer operations. In AOV mode, to maximize power saving, the camera locks the PTZ motor in AOV sleep mode, causing the monitoring view to be fixed in one position for a long time, which cannot effectively cover a wider area, resulting in serious monitoring blind spots and ineffective utilization of the monitoring equipment's monitoring resources.

[0003] This indicates that there is a problem with the low utilization rate of monitoring resources in AOV mode in related technologies.

[0004] There is currently no effective solution to the aforementioned problems in the relevant technologies. Summary of the Invention

It also writes cached data from the data buffer into the memory. Once the PTG has rotated to the target location and all cached data is written to memory, the monitoring device is controlled to transition from the data writing state to a low-power state. Because the PTG can be controlled during the monitoring device's wake-up period, it allows the device to monitor different areas. Therefore, this addresses the problem of low resource utilization in AOV mode in related technologies, thereby improving the resource utilization of monitoring devices. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] According to one aspect of the embodiments of this application, a control method for a monitoring device is provided. Optionally, in this embodiment, the control method for the monitoring device may be applied, but is not limited to, to applications such as... Figure 1 The hardware environment shown includes terminal device 102 and server 104. Server 104 can be connected to terminal device 102 via a network and can be used to provide services (e.g., application services, etc.) to terminal device 102 or clients installed on terminal device 102. A database can be set up on server 104 or independently of server 104 to provide data storage services for server 104.

[0027] The aforementioned network may include, but is not limited to, at least one of the following: wired network and wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: wide area network (WAN), metropolitan area network (MAN), and local area network (LAN). The aforementioned wireless network may include, but is not limited to, at least one of the following: Wireless Fidelity (WIFI) and Bluetooth. Terminal device 102 may be, but is not limited to, a personal computer (PC), mobile phone, tablet computer, etc. Server 104 may be, but is not limited to, a cloud server, server cluster, or other server types.

[0028] The control method for the monitoring device in this embodiment can be executed by server 104, terminal device 102, or jointly by server 104 and terminal device 102. Alternatively, the control method for the monitoring device in this embodiment can be executed by a client installed on the terminal device 102.

[0029] Taking the control method of the monitoring device in this embodiment executed by terminal device 102 (server 104) as an example, Figure 2 This is a flowchart illustrating an optional control method for a monitoring device according to an embodiment of this application, as shown below. Figure 2 As shown, the process of this method may include the following steps:

[0030] Step S202: When the monitoring device switches from a low-power state to a data writing state, determine the target location, wherein the data writing state is used to indicate that the cached data in the data buffer is written to the memory;

[0031] In this embodiment, the control method for the monitoring device can be applied to the monitoring device, which may include a pan-tilt unit, a memory, and a data buffer. The monitoring device may be a device with an AOV (Area of ​​View) mode, which enters a low-power state when not woken up, or after being woken up for a period of time.

[0032] In this embodiment, before determining the target location, the method further includes: determining the remaining storage space in the data buffer; if the remaining storage space is less than a predetermined threshold, switching the monitoring device from a low-power state to a write state; determining the number of images stored in the buffer; if the number of images is greater than a preset number, switching the monitoring device from a low-power state to a write state; and determining the target duration for the monitoring device to enter the low-power state; if the target duration is greater than a preset duration, switching the monitoring device from the low-power state to a write state.

[0033] In this embodiment, the target location can be determined based on historical monitoring data of the monitoring equipment, environmental information of the monitoring area of ​​the monitoring equipment, selection instructions, or preset locations.

[0034] Step S204: Control the pan-tilt unit to rotate to the target position in order to monitor the monitoring sub-area corresponding to the target position;

[0035] In this embodiment, the monitoring area of ​​the monitoring device may include multiple monitoring sub-areas, and one monitoring sub-area corresponds to one pan-tilt position. For example, when monitoring sub-area 1 corresponds to position 1, when the pan-tilt is rotated to position 1, the monitoring field of the monitoring device is monitoring sub-area 1.

[0036] Step S206: Write the cached data in the data cache into the memory;

[0037] In this embodiment, when the monitoring device is woken up, the cached data in the data cache can be written to the memory, and after the writing is completed, the data in the data cache is deleted to free up the space of the data cache.

[0038] It should be noted that steps S204 and S206 can be executed synchronously or sequentially. When they are sequential, step S204 can be executed first, followed by step S206, or vice versa.

[0039] Step S208: When the gimbal has rotated to the target position and all the cached data has been written into the memory, control the monitoring device to enter the low-power state from the data writing state.

[0040] In this embodiment, the "power consumption window" during which the monitoring device is forcibly woken up due to necessary internal operations (such as writing cached data to storage) is considered a valuable opportunity to optimize the monitoring perspective. During this window, the pan-tilt-zoom (PTZ) rotation operation is performed in parallel. The monitoring device enters AOV low-power mode, acquiring images at a preset low frame rate interval and storing the compressed image data in a fixed-size circular buffer, i.e., a data buffer. Preset wake-up conditions are continuously monitored. When any condition is met (e.g., a. buffer storage space occupancy reaches a threshold (e.g., 6MB); b. cached image frame count reaches a threshold (e.g., 600 frames); c. a low-power timer times out), the system immediately exits AOV mode, waking up the main processor, memory controller, and other core units. The monitoring device can first execute a high-priority task, that is, completely writing all image data in the buffer to external persistent storage (e.g., an SD card). During the parallel writing operation, the "strategy decision module" can be invoked to calculate a target position, including coordinates, horizontal angle, and pitch angle, based on one or more preset strategies. Subsequently, the "PTZ control module" drives the PTZ motor to rotate the camera lens to the target position. The monitoring equipment can continuously monitor the status of two tasks: a. whether data writing is complete; b. whether the pan-tilt unit has stably reached the target position. Once both are completed, it immediately re-enters AOV low-power mode and begins a new round of interval image acquisition from a new lens perspective.

[0041] This application enables the monitoring device to determine a target location and control the pan-tilt unit (PTZ) to rotate to the target location while switching from a low-power state to a data writing state, thereby monitoring the corresponding sub-area. It also writes cached data from the data buffer into the memory. Once the PTG has rotated to the target location and all cached data is written to memory, the monitoring device is controlled to transition from the data writing state to a low-power state. Because the PTG can be controlled during the monitoring device's wake-up period, it allows the device to monitor different areas. Therefore, this addresses the problem of low resource utilization in AOV mode in related technologies, thereby improving the resource utilization of monitoring devices.

[0042] In an exemplary embodiment, determining the target location includes: if the target object tracked by the monitoring device disappears from the monitoring area of ​​the monitoring device, determining the last detected disappearance location of the target object and determining the disappearance location as the target location; or, if a preset location exists, determining the preset location as the target location; or, if the preset location does not exist, determining the heat value of each monitoring sub-area of ​​the monitoring device based on historical monitoring data, determining a first monitoring sub-area based on the heat value, and determining the first PTZ position corresponding to the first monitoring sub-area as the target location, wherein the monitoring area of ​​the monitoring device includes multiple monitoring sub-areas, and the multiple monitoring sub-areas include the first monitoring sub-area; or, if a historical access location exists and the historical access location is within its validity period, determining the historical access location as the target location, wherein the historical access location is the location specified in the control command input by the user through the target interface; or, randomly determining the target location within the rotation range of the PTZ; or, determining the environmental information of the monitoring area and determining the target location based on the environmental information; or, determining other monitoring areas of other devices located in the same area as the monitoring device and determining the target location based on the other monitoring areas. In this embodiment, after the monitoring device switches from a low-power state to a data writing state, if the monitoring device detects a target object, it can track the target object. When the target object disappears, the position of the PTZ at the time of disappearance can be determined as the target location. For example, the camera is in sleep mode at position A in AOV mode. Its low-power sensing unit (such as a PIR sensor or a low-power AI chip) detects a valid target (such as a human figure) at position B, the system is woken up, and high-definition recording and automatic PTZ tracking functions are started, so that the lens continuously follows the target's movement.

[0043] In this embodiment, it can also check whether there is a user-defined key preset position (such as "gate" position B) that must be returned to after the event ends, i.e., a preset position. If it exists, the pan-tilt unit moves to that preset position. For example, the user can set multiple preset positions for the camera through the client (such as position P1 - gate, P2 - garage, P3 - backyard). The strategy decision module can maintain a preset position pointer. Each time a decision is needed, the pointer points to the next preset position sequentially (P1→P2→P3→P1...) or randomly, and uses the coordinates of that preset position as the target position. This setting achieves the effects of simple implementation, high determinism, and ensuring that key points are periodically covered.

[0044] In this embodiment, if there are no user presets, the heat value of each monitoring sub-area can be determined based on the "location-time heat map" generated from historical monitoring data. The area with the highest heat value is determined as the first monitoring sub-area, and the first PTZ position corresponding to the first monitoring sub-area is determined as the target position. When the PTZ is rotated to the first PTZ position, the monitoring field of view of the monitoring device is the first monitoring sub-area.

[0045] In this embodiment, the user's temporary monitoring intentions can be captured and respected. The user can actively interact with the scene through a client (such as a mobile app), for example, by initiating a real-time video stream request (pull stream) to the camera. The camera is thus forcibly awakened, exits AOV mode, and establishes a real-time video transmission channel. The user can use the directional keys on the client interface or directly click on a point on the electronic map to control the pan-tilt unit to rotate to its desired monitoring angle (position E). The user can then stop operating and exit the real-time preview interface or close the client. After the historical access period ends, the target location is determined based on the historical access locations.

[0046] In this embodiment, a legal location coordinate within the gimbal's movement range can be randomly generated as the target location with a small probability (e.g., 5% or 10%), ignoring other strategies during decision-making. Randomly determining the target location breaks the "monitoring mindset" that might result from intelligent learning, actively explores non-hotspot areas, effectively avoids monitoring blind spots caused by model rigidity, and enhances the system's exploratory nature and robustness.

[0047] In this embodiment, the target location can also be determined based on environmental information, which may include weather information, sound information, light information, etc. This environmental information can be data collected by sensors integrated into the monitoring equipment, or environmental data collected by other monitoring equipment located in the same area as the monitoring equipment.

[0048] In this embodiment, in a system deploying multiple AOV cameras, the devices can exchange information via low-power communication protocols (such as Zigbee, LoRa) or a local area network. When a monitoring device (Device A) needs to determine the target location, it queries neighboring devices (i.e., other monitoring devices, such as Devices B and C) for their recent event records and hotspot area information. Device A combines its own and its neighbors' information to determine a location that can fill in the blind spots of its neighbors or create an intersecting view with its neighbors to enhance the monitoring effect of a specific area. This elevates intelligence from a single point to a system-level intelligence, enabling collaborative operation between devices and optimizing the overall coverage efficiency of the monitoring network.

[0049] In an exemplary embodiment, determining the disappearance location as the target location includes: controlling the pan-tilt unit (PTZ) to rotate to the disappearance location and remaining there for a preset observation period; if the monitoring device does not detect the target object within the preset observation period, the disappearance location is determined as the target location. In this embodiment, the target disappears from the monitoring screen at location C during its movement (e.g., obscured by an obstacle or out of view), and the automatic tracking function stops due to target loss. Afterward, the system does not immediately perform a large-scale pan-tilt rotation, but instead controls the PTG to remain stationary at the last disappearance location C and initiates an observation period of a preset observation period (e.g., 10 to 30 seconds). This is based on the reasonable assumption that the target's behavior may be continuous. If the target reappears near location C during the observation period, the system immediately reactivates the automatic tracking function and continues tracking the target. If the target still does not appear after the observation period ends, the system determines that the independent event chain has essentially ended and switches to the regular location decision logic. The disappearance location is then determined as the target location. In an exemplary embodiment, before determining the historical access location as the target location, the method further includes: determining the end time of the access request corresponding to the historical access location; starting a first timer at the end time to obtain a first timer duration; starting a second timer to obtain a second timer duration if the first timer duration reaches a first predetermined duration; determining that the historical access location is within the validity period if the second timer duration is less than or equal to the second predetermined duration; and determining that the historical access location is outside the validity period if the second timer duration is greater than the second predetermined duration. In this embodiment, when the system detects that a user control session has ended, i.e., the access request has ended, it starts a "no-operation confirmation timer" (e.g., 60 seconds) to prevent the user from returning after a brief absence. After the timer expires, i.e., the first timer duration reaches the first predetermined duration, it confirms that the user interaction has truly ended. The system marks the current location E of the PTZ as a "last user-specified location" with high priority, i.e., a historical access location, and sets a validity period (e.g., 12 hours or 24 hours) for this mark. If the historical access location is within its validity period (i.e., the second timing duration is less than or equal to the second predetermined duration), it can be determined that the historical access location is within its validity period. The system then designates the historical access location as the target location. The system controls the camera to directly enter AOV low-power mode at location E, thereby transforming the user's temporary intent into a subsequent monitoring focus. Within the validity period of the "user-specified location" marker, whenever the camera needs to select a target location due to the forced wake-up described in Part 1, the "strategy decision module" will prioritize querying this marker. If the marker is valid, the pan-tilt-zoom (PTZ) will rotate to location E. If the marker is invalid or does not exist, the system will degrade to using conventional intelligent strategies (such as polling preset positions or using heatmaps) to select the target location.In an exemplary embodiment, determining the heat value of each monitoring sub-area of ​​the monitoring device based on historical monitoring data includes: performing the following operations for each monitoring sub-area to determine the heat value of the monitoring sub-area: determining the event occurrence frequency of events occurring in the monitoring sub-area; determining the event type and event duration of events occurring in the monitoring sub-area; determining the type weight corresponding to the event type; determining the duration weight corresponding to the event duration; and determining the heat value based on the event occurrence frequency, the type weight, and the duration weight. In this embodiment, a location-time heat map can be determined based on historical monitoring data. During normal monitoring mode or when an event is triggered, metadata can be continuously recorded, including but not limited to: the location coordinates of the target, timestamp, target type (person, vehicle, pet), event type (motion detection, area intrusion), and duration. The space can be divided into grids by time (e.g., by hour, or by weekday / weekend), and a "heat value" can be calculated for each grid. The heat value can be calculated by the following weighting factors: event occurrence frequency × time decay factor × event type weight × average duration weight. When a target location needs to be selected, the system queries the heatmap based on the current time and selects the center area of ​​the grid with the highest heat value within the current time period as the target location. By determining the location corresponding to the highest heat value as the target location, the monitoring behavior can have self-learning and adaptive capabilities, and can proactively focus on areas with high incidence of anomalies.

[0050] In an exemplary embodiment, determining the popularity value based on the event occurrence frequency, the type weight, and the duration weight includes: determining the popularity value as the product of the event occurrence frequency, the type weight, the duration weight, and the time decay factor. In this embodiment, the popularity value can be expressed as event occurrence frequency × time decay factor × event type weight × duration weight. The duration weight can be an average duration weight, and the time decay factor can be preset.

[0051] In this embodiment, a rule-based heat accumulation algorithm can be used instead of a complex machine learning model. For example, by simply counting the number of events occurring in each region within different time periods and applying a simple time decay factor, computational and storage requirements can be significantly reduced. Furthermore, fixed-point numbers can be used instead of floating-point numbers for algorithmic operations on embedded chips, improving computational efficiency.

[0052] In an exemplary embodiment, determining the target location based on the environmental information includes: if the current time falls within a preset time period, determining the illumination information included in the environmental information, determining the second monitoring sub-area corresponding to the target illumination information that meets preset conditions, and determining the second gimbal position corresponding to the second monitoring sub-area as the target location; or, determining the sound information included in the environmental information, determining the sound source direction based on the sound information, and determining the target location based on the sound source direction; or, determining the target weather information included in the environmental information, and determining the target location corresponding to the target weather information in the correspondence between weather information and gimbal positions. In this embodiment, when making a decision, data from built-in or external environmental sensors of the camera can be referenced. For example, a light sensor: at night, areas with low light or supplementary lighting near the turning point are preferentially selected to ensure image availability. That is, when the target illumination information indicates that there is illumination in the second monitoring sub-area, the second gimbal position corresponding to the second monitoring sub-area is determined as the target location. The preset conditions may include illumination intensity greater than a preset intensity.

[0053] In this embodiment, the target location can also be determined based on the sound information collected by the sound sensor. If an unusual noise (such as the sound of breaking glass) is detected from a specific direction, the device can temporarily turn in that direction.

[0054] In this embodiment, during rainy weather, the monitoring priority for areas such as doors and windows, and areas prone to leaks can be automatically increased. Each weather information can correspond to a specific pan-tilt-zoom (PTZ) position, and this correspondence can be pre-set. When the weather information indicates rain, the PTG position can be the location corresponding to doors and windows, or areas prone to leaks. When the weather information indicates sunny weather, the PTG position can be the location corresponding to main gates, garages, or similar areas. This setup allows the monitoring strategy to dynamically link with the physical environment, making the monitoring method more intelligent and practical.

[0055] In an exemplary embodiment, controlling the gimbal to rotate to the target position includes: determining a first power consumption required for the gimbal to rotate from its current position to the target position; determining a rotation budget for the monitoring device; controlling the gimbal to rotate to the target position if the first power consumption is less than or equal to the rotation budget; adjusting the target position to obtain an adjusted position if the first power consumption is greater than the rotation budget, wherein a second power consumption required for the gimbal to rotate from its current position to the adjusted position is less than the rotation budget; and controlling the gimbal to rotate to the adjusted position. In this embodiment, after the strategy decision module outputs the target position, the gimbal control module estimates the first power consumption required to complete the rotation based on the angle difference between the current gimbal position and the target position, and the gimbal motor characteristic parameters (such as torque-current curves).

[0056] In this embodiment, a dynamic "rotation power consumption budget" can be maintained. This budget is linked to the device's current remaining battery power. For example, when the battery power is >80%, the daily budget is higher; when the battery power is <20%, the budget drops sharply or becomes zero. The first power consumption of this rotation can be compared with the current budget. If the first power consumption is lower than the rotation budget, the rotation is allowed to proceed, and the corresponding value is deducted from the budget. If the first power consumption exceeds the rotation budget or the angle is too large, the decision is intervened, and optimization suggestions are provided, such as: a) suggesting that the strategy decision module select a closer alternative position; b) breaking down the large rotation into multiple small rotations, which are completed in batches during subsequent wake-ups.

[0057] In this embodiment, a "Smart Cruise Power Consumption Report" can be provided to users in the App to show the approximate impact of the function on battery life, thereby increasing user trust.

[0058] In an exemplary embodiment, after controlling the gimbal to rotate to the target position, the method further includes: generating a rotation log of the gimbal rotation, wherein the rotation log includes the reason for the rotation; and pushing the rotation log to a target application, wherein the target application is an application associated with the monitoring device. In this embodiment, every gimbal rotation not triggered by the user can be recorded and a plaintext log can be generated. For example: "[2025-08-10 06:11] The system was woken up due to cache write. According to the 'high heat in the backyard late at night' rule, the gimbal has automatically turned to the preset position 'overlooking the backyard'." The target application can provide visual feedback. On the client's electronic map, not only is the current position of the gimbal displayed, but the recent automatic rotation trajectory and reason can also be shown through animation or prompts. This setting can reduce the computational overhead of the intelligent strategy and explain the gimbal behavior to the user, solving the "black box" problem.

[0059] In an exemplary embodiment, determining the target location includes: displaying rules for determining the target location in the display interface of the target application; receiving a selection instruction input by the user through the display interface; and determining the target location based on the target rules included in the selection instruction. In this embodiment, the user can independently enable or disable each smart strategy in the App (e.g., enabling "Learning Based on Historical Data" and disabling "Random Supplemental Scan"). The target rules may include, when the target object tracked by the monitoring device disappears from the monitoring area of ​​the monitoring device, determining the last detected disappearance location of the target object and identifying the disappearance location as the target location; and / or, if a preset location exists, identifying the preset location as the target location; and / or, if the preset location does not exist, determining the heat value of each monitoring sub-area of ​​the monitoring device based on historical monitoring data, determining a first monitoring sub-area based on the heat value, and identifying the first PTZ position corresponding to the first monitoring sub-area as the target location, wherein the monitoring area includes multiple monitoring sub-areas and multiple... The monitoring sub-region includes the first monitoring sub-region; and / or, if a historical access location exists, determine the validity period of the historical access location, and if the historical access location is within the validity period, determine the historical access location as the target location, wherein the historical access location is the location specified in the control command input by the user through the target interface; and / or, randomly determine the target location within the rotation range of the pan-tilt unit; and / or, determine the environmental information of the monitoring area, and determine the target location based on the environmental information; and / or, determine other monitoring areas of other devices located in the same area as the monitoring device, and determine the target location based on the other monitoring areas.

[0060] In one exemplary embodiment, a user can manually define "areas of focus" and "areas to ignore" in the target application's display interface, such as a panoramic view. When calculating a heatmap or selecting a target, the strategy decision module assigns higher weight to the areas of focus and completely ignores the designated areas.

[0061] In one exemplary embodiment, advanced parameters can be customized through the target application's display interface: providing users with advanced setting options such as: the effective duration of the "last specified location by the user" (1 hour / 6 hours / 12 hours / 24 hours); the duration of the "observation period after the target disappears"; and whether the "smart rotation" function automatically turns off when the battery is low (e.g., <15%).

[0062] In one exemplary embodiment, an S-shaped acceleration / deceleration curve can be used to control the gimbal motor, avoiding sudden starts and stops and reducing mechanical noise and vibration. Once the gimbal's physical rotation stops, an electronic image stabilization algorithm is immediately activated to shorten the image stabilization wait time, ensuring that the first frame captured in AOV mode is clear and usable. To address the issue of frequent data writes to the data buffer required for intelligent learning, the storage read / write strategy can be optimized by writing data to different blocks of the Flash memory, achieving wear leveling and extending memory lifespan. Through a combination of hardware and software design, the overall system performance and user experience are improved.

[0063] In one exemplary embodiment, the problems that may be encountered in engineering implementation, such as precise power consumption control, computational resource consumption, user trust and hardware performance dependence, can be solved by introducing adaptive power management, algorithm lightweighting and interpretability, enhanced user control and hardware-software co-optimization, making the core solution more robust, efficient and user-friendly.

[0064] The camera enters AOV mode at viewpoint A (living room) with 85% battery. The buffer is full, and the system wakes up. The strategy decision module calculates the next optimal position as viewpoint B (backyard), which requires 5 units of power consumption. The power management submodule queries the daily rotation power budget corresponding to the current battery level (85%), which is 50 units. The estimated power consumption for this rotation is 5 units, within the budget. The submodule approves this rotation. The gimbal control module uses a smooth motion curve to smoothly rotate the camera to viewpoint B. After data writing is complete, the system enters AOV mode, and software stabilization ensures an immediate clear image. The user receives a wake-up notification, opens the app to check the logs, and sees the record: "The system woke up at XX time due to a full buffer and rotated to the backyard according to the rules." The user understands this action. The user believes the kitchen needs more attention, so they designate the kitchen area as a "priority area" on the app map and manually rotate the gimbal to viewpoint C (kitchen). Before exiting the app, the user sets the validity period of the "last user-specified location" to 6 hours. The system locks viewpoint C. After a period of time, the device battery level drops to 18%. The power management submodule reduces the daily rotation budget to 5 units. When the device is woken up again, even if the strategy decision module suggests turning to a hotspot area that requires 10 units of power consumption, the power management submodule will intervene and suggest that the gimbal make only minor adjustments or remain in its original position to prioritize battery life.

[0065] In the aforementioned embodiments, the unavoidable system wake-up overhead is transformed into an opportunity for optimizing the monitoring perspective, significantly expanding the effective monitoring range with minimal additional power consumption. By introducing a hierarchical decision-making model and multiple intelligent strategies, the camera can understand the scene, learn patterns, and respect human intent, upgrading from a passive recording tool to an active security partner. This addresses the pain point of ignored intent after manual user control, achieving seamless integration of automation and manual control, greatly improving product usability and user trust. Combining deterministic strategies (preset positions), learning strategies (heatmaps), and exploratory strategies (random scanning), the system can both grasp key points and adapt to changes, avoiding getting trapped in local optima. Implemented through software algorithm upgrades, it requires minimal hardware modifications and is easy to deploy and promote on existing products. Through adaptive power management, it ensures that the intelligent rotation function will not negatively impact the core battery life target under any power level, upgrading the solution from "conceptually feasible" to "practically reliable." The lightweight design allows advanced intelligent functions to run smoothly on resource-constrained embedded devices; the interpretable functions eliminate user concerns about "black box" operation, enhancing product trust. With a wealth of user-customizable options, it meets the diverse needs of different users and in different scenarios, achieving a perfect balance between intelligence and controllability. Software and hardware co-optimization improves motion smoothness, image stability, and storage reliability, resulting in a superior overall user experience.
