Description
Technical Field
[0001] This invention relates to the field of security monitoring technology, and in particular to an outdoor low-power cellular network monitoring camera. Background Technology
[0002] Traditional outdoor surveillance equipment generally relies on mains power or solar power, resulting in high wiring costs and complex installation. Existing low-power surveillance equipment mostly uses rechargeable batteries, requiring regular maintenance and charging, and suffers from the following technical drawbacks:
[0003] 1. Risk of accidental activation: Conventional button-type power-on design is susceptible to accidental activation due to environmental factors such as vibration and rain, resulting in wasted battery power and shortened actual working time of the device;
[0004] 2. Short battery life: The presence of the charging port not only increases the difficulty of waterproof design, but also causes oxidation and corrosion of the port due to long-term outdoor use, which may lead to poor contact or water ingress and short circuit, resulting in device damage.
[0005] 3. Insufficient power consumption control: Most devices only reduce power consumption through simple sleep mode, without implementing dynamic power-down management of core modules, and the standby current is generally higher than 500μA;
[0006] 4. Deployment complexity: The network configuration process between the device and the mobile phone relies on Bluetooth or Wi-Fi, and the initial configuration cannot be completed in areas without signal coverage. Summary of the Invention
[0007] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an outdoor low-power cellular network surveillance camera, which aims to solve the problem of how to avoid the conventional button power-on design being easily triggered by environmental factors such as vibration and rain, resulting in battery power waste and shortening the actual working time of the device.
[0008] The technical solution adopted by this invention to solve its technical problem is as follows: an outdoor low-power cellular network surveillance camera, comprising a housing, a motherboard, and an anti-accidental touch power-on module. The motherboard is installed inside the housing and has a power-on circuit. The housing has a power-on hole. The anti-accidental touch power-on module includes an elastic conductive post and a one-time fuse circuit disposed on the motherboard. The one-time fuse circuit is connected in series in the power-on circuit. The anti-accidental touch power-on module triggers the power-on circuit by inserting a special probe into the power-on hole and axially pressing the elastic conductive post. After power-on, the one-time fuse circuit is permanently disconnected, achieving irreversible power-on.
[0009] As a further improvement of the present invention: the outer shell is provided with a groove, and the power-on hole is embedded in the groove. The depth of the groove is ≥2mm, and the diameter of the power-on hole is ≤1mm. The groove depth ≥2mm and the power-on hole diameter ≤1mm form a double physical protection: on the one hand, it can prevent outdoor dust and rainwater from directly intruding into the power-on hole, reducing oxidation and damage to the internal elastic conductive pillars and improving structural reliability; on the other hand, it can effectively filter unintentional interference such as vibration and foreign object contact, avoiding accidental triggering of the power-on circuit and ensuring that battery power is not wasted. The layout of the power-on hole embedded in the groove does not damage the integrity of the outer shell and further limits the uniqueness of the triggering operation. A special probe is required to fit the hole diameter and press axially, significantly reducing the risk of accidental power-on in complex outdoor environments.
[0010] As a further improvement of the present invention: the one-time fuse circuit includes a self-resetting fuse and a one-time fuse resistor connected in series. The self-resetting fuse and the one-time fuse resistor are disposed on the motherboard. After power-on, the one-time fuse resistor is permanently disconnected. The series design of the one-time fuse resistor and the self-resetting fuse forms dual protection: the self-resetting fuse can automatically disconnect when there is an abnormal current at the moment of power-on, avoiding damage to the motherboard circuit from surge current, and automatically recovers after the fault is cleared, ensuring safety during the power-on process; the one-time fuse resistor is permanently disconnected after power-on, achieving irreversible power-on.
[0011] As a further improvement of the present invention, it also includes a dynamic power management module, a camera module and a 4G module, a CPU, a real-time clock timer and an interrupt controller, wherein the camera module and the 4G module, the CPU, the real-time clock timer and the interrupt controller are mounted on the motherboard, and the dynamic power management module includes an active mode, a transmission mode and a deep sleep mode.
[0012] In the active mode, the camera module and 4G module operate; in the transmission mode, the camera module is powered down, and the 4G module enters discontinuous reception mode; in the deep sleep mode, the CPU enters WFI state, and the real-time clock timer and interrupt controller operate; the dynamic power management module receives cloud instructions via the MQTT protocol and configures the periodic wake-up cycle. By adopting three levels of energy efficiency modes—active mode, transmission mode, and deep sleep mode—the active mode ensures image acquisition and transmission efficiency; the transmission mode reduces power consumption by powering down the camera and having the 4G module enter DRX mode; and the deep sleep mode retains only the core components running, resulting in an ultra-low overall current of ≤150μA that significantly extends battery life. By integrating the camera module, 4G module, CPU, real-time clock timer, and interrupt controller onto the motherboard, the layout is compact, highly efficient, and the power consumption switching response is rapid, ensuring effective monitoring while minimizing energy consumption.
[0013] As a further improvement of the present invention, it also includes a QR code configuration module. This module comprises an identification code located on the bottom of the casing, a terminal application, and a cloud configuration server. The identification code contains an encrypted unique device identifier. The terminal application obtains the unique device identifier by scanning the identification code and sends a binding request to the cloud configuration server. The cloud configuration server pushes configuration parameters to the device via a 4G network and the MQTT protocol to complete the initialization of the working mode. The embedded encrypted unique device identifier in the identification code effectively prevents unauthorized binding and information tampering, ensuring device configuration security. The terminal application can obtain the identifier simply by scanning the code, eliminating the need for manual input, making the operation simple and intuitive, and improving the convenience and security of configuration. Relying on the 4G network and the MQTT protocol, it does not depend on Bluetooth or Wi-Fi, and can complete configuration even in areas with no signal coverage, overcoming environmental limitations. The cloud configuration server remotely pushes configuration parameters and automatically completes the initialization of the working mode, eliminating the need for on-site debugging, significantly shortening device launch time and improving deployment efficiency.
[0014] As a further improvement of the present invention: the identification code is a QR code, the terminal application is a WeChat mini program or a mobile APP, and the configuration parameters include the settings of the shooting cycle and image resolution.
[0015] As a further improvement of the present invention, the configuration process of the QR code configuration module includes: S1: The terminal application scans the identification code to obtain the device's unique identifier; S2: The terminal application sends the "device's unique identifier + user account" to the cloud configuration server via the 4G network; S3: After verifying user permissions, the cloud configuration server pushes parameters such as the shooting cycle, image resolution, and data upload frequency to the device; S4: The device receives the parameters and writes them to Flash storage, completing the initialization of the working mode. By obtaining the device's unique identifier through QR code scanning in step S1, manual input is eliminated, simplifying the operation and avoiding input errors. Step S2 relies on the 4G network for information transmission, eliminating the need for Bluetooth or Wi-Fi, enabling communication even in the absence of auxiliary signals in the field, overcoming environmental limitations. Step S3, where the cloud configuration server verifies user permissions, prevents unauthorized configuration, and the pushed parameters such as the shooting cycle can be customized to adapt to different monitoring scenarios. Step S4, where the device receives the parameters and writes them to Flash storage to complete the initialization of the working mode, eliminates the need for on-site debugging, significantly shortening the deployment time. The entire process is interconnected, balancing security and practicality, and offering advantages such as high convenience, high security, and high flexibility.
[0016] As a further improvement of the present invention, the outer shell is integrally injection molded using a PC+ABS alloy (a plastic alloy composed of polycarbonate and acrylonitrile-butadiene-styrene blend). By adopting a PC+ABS alloy and combining it with an integral injection molding process, an optimized balance between performance and cost is achieved. The PC component endows the shell with excellent rigidity, impact resistance, and high and low temperature resistance (typically -40℃ to 120℃), ensuring that it does not deform or crack in harsh outdoor environments; the ABS component enhances the material's toughness, flowability, and processability, enabling complex structures to be precisely molded in one step. The integral molding process completely eliminates splicing gaps, fundamentally preventing the risk of water leakage and greatly simplifying subsequent waterproof assembly procedures.
[0017] As a further improvement of the present invention: the inside of the outer casing is provided with a battery compartment, the battery compartment is equipped with a battery, the battery is electrically connected to the motherboard, and the battery is a lithium thionyl chloride battery.
[0018] As a further improvement of the present invention: a lens module is provided inside the housing, the lens module is electrically connected to the camera module, and a butyl rubber sealing ring is provided between the lens module and the housing. The use of the butyl rubber sealing ring achieves a static seal between the lens module and the housing. Butyl rubber has extremely low water vapor permeability, excellent elastic recovery, and resistance to environmental aging, maintaining its compression resilience for a long time and effectively coping with thermal expansion and contraction caused by outdoor temperature cycles. Its excellent damping characteristics also help to buffer minor vibrations.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] 1. This invention utilizes a specific triggering mechanism between the power-on hole on the outer casing and the elastic conductive posts on the motherboard. A specific operation is required to activate the power-on circuit, effectively filtering out unintentional touches caused by outdoor vibrations, rain, or foreign object collisions. This avoids the problem of conventional button-type power-on designs being susceptible to accidental activation due to vibrations, rain, and other environmental factors, leading to wasted battery power and shortened device operating time. The elastic conductive posts possess stable trigger response characteristics, ensuring reliable and seamless contact, guaranteeing accurate power-on operation, and reducing the probability of trigger failures or accidental activations.
[0021] 2. This invention uses a one-time fuse circuit connected in series in the power-on circuit. Once the device is powered on, the one-time fuse circuit permanently disconnects, achieving irreversible power-on. By encapsulating the mainboard inside the casing, and with the structural layout of the power-on hole, the path of external environmental erosion to the internal circuitry is reduced, improving the device's protective stability in complex outdoor environments and extending its service life.

However, those skilled in the art will understand that the exemplary embodiments can be implemented without these specific details.

[0030] Please see Figure 1-3An outdoor low-power cellular network surveillance camera includes a housing 11, a motherboard 9, and an anti-accidental touch power-on module. The motherboard 9 is installed inside the housing 11 and has a power-on circuit. The housing has a power-on hole 1. The anti-accidental touch power-on module includes an elastic conductive post and a one-time fuse circuit disposed on the motherboard 9. The one-time fuse circuit is connected in series in the power-on circuit. The anti-accidental touch power-on module triggers the power-on circuit by inserting a special probe into the power-on hole 1 and axially pressing the elastic conductive post. After power-on, the one-time fuse circuit is permanently disconnected, achieving irreversible power-on. The special probe is used to insert into the power-on hole, similar to the probe used when changing a SIM card in a mobile phone.
[0031] The power-on hole 1 on the outer casing 11 forms a specific trigger engagement with the elastic conductive post on the motherboard 9. A specific operation is required to activate the power-on circuit, effectively filtering out unintentional contact from outdoor vibrations, rain impacts, and collisions with foreign objects, thus preventing unnecessary battery drain. The elastic conductive post has stable trigger response characteristics, reliable contact without jamming, ensuring the accuracy of the power-on operation and reducing the probability of trigger failure or false triggering.
[0032] A one-time fuse is connected in series with the power-on circuit. Once the device is powered on, the one-time fuse permanently disconnects, achieving irreversible power-on and preventing malicious shutdown during operation. The motherboard 9 is encapsulated inside the casing 11. Combined with the structural layout of the power-on hole 1, this reduces the path of external environmental erosion to the internal circuitry, improves the device's protective stability in complex outdoor environments, and extends its service life.
[0033] In some embodiments, the outer casing 11 is provided with a groove, the power-on hole 1 is embedded in the groove, the depth of the groove is ≥2mm, and the diameter of the power-on hole 1 is ≤1mm.
[0034] With a groove depth of ≥2mm and a power-on hole diameter of ≤1mm, dual physical protection is formed: on the one hand, it prevents outdoor dust and rainwater from directly entering the power-on hole 1, reducing oxidation and damage to the internal elastic conductive pillars and improving structural reliability; on the other hand, it effectively filters unintentional interference such as vibration and foreign object contact, avoiding accidental triggering of the power-on circuit and ensuring that battery power is not wasted. The layout of the groove embedded in the power-on hole 1 does not affect the integrity of the outer shell 11, and further limits the uniqueness of the triggering operation. A special probe is required to fit the hole diameter and press axially, which greatly reduces the risk of accidental power-on in complex outdoor environments and perfectly meets the needs of low-power outdoor and unattended use.
[0035] In one specific embodiment, the opening hole 1 is manufactured using CNC machining, with a hole diameter tolerance controlled within ±0.05mm, and the inner wall is anodized with a thickness of 5μm; the elastic conductive post is made of beryllium copper, and its triggering force is 3±0.5N when its compression stroke is 2mm.
[0036] The opening hole 1 is CNC machined with a high precision tolerance of ±0.05mm to ensure a precise fit with the dedicated probe, avoiding trigger failure caused by insertion / removal jamming or excessive gaps. The inner wall undergoes 5μm anodizing treatment to improve wear resistance and rust prevention, reducing the erosion of the hole wall by outdoor rain and dust. The elastic conductive post is made of beryllium copper, which combines excellent elasticity and conductivity. The precise triggering force of 3±0.5N at a compression stroke of 2mm not only filters out unintentional interference such as slight touches, but also ensures stable conduction during operation, further enhancing the anti-accidental touch effect.
[0037] In some embodiments, the one-time fuse circuit includes a resettable fuse and a one-time fuse resistor connected in series. The resettable fuse and the one-time fuse resistor are disposed on the motherboard 9. After power-on, the one-time fuse resistor is permanently disconnected.
[0038] The system employs a series connection of a one-time fusible resistor and a self-resetting fuse to provide dual protection: the self-resetting fuse automatically disconnects when there is an abnormal current during power-on, preventing surge current from damaging the motherboard circuit 9, and automatically recovers after the fault is cleared, ensuring safety during the power-on process; the one-time fusible resistor permanently disconnects after power-on, enabling irreversible power-on.
[0039] In one specific embodiment, the one-time fusible resistor is a 1206 type one-time fuse with a 0402 package, a rated current of 1A, and a fusing time of ≤50ms.
[0040] The 1206 type one-time fuse, which adopts 0402 package, is small and compact; its fast fusing time of ≤50ms ensures that the circuit is quickly and permanently disconnected after power-on. The fuse has timely fusing response, reliable action, and low failure risk, providing a solid guarantee for the long-term stable operation of equipment in outdoor unattended scenarios.
[0041] In some implementations, it also includes a dynamic power management module, a camera module and a 4G module, a CPU, a real-time clock timer and an interrupt controller, wherein the camera module and the 4G module, the CPU, the real-time clock timer and the interrupt controller are mounted on the motherboard 9, and the dynamic power management module includes an active mode, a transmission mode and a deep sleep mode.
[0042] In the activity mode, the camera module and 4G module operate at full power, and the CPU works at a 400MHz main frequency.
[0043] In the transmission mode, the camera module is powered off, and the 4G module enters the discontinuous reception mode (DRX mode).
[0044] In the deep sleep mode, the CPU enters WFI state, and only the real-time clock timer (RTC timer) and interrupt controller run, with the total current ≤150μA;
[0045] The dynamic power consumption management module receives cloud instructions via MQTT protocol 19 and configures a periodic wake-up cycle; the periodic wake-up cycle ranges from 1 minute to 24 hours.
[0046] Employing a three-tiered energy efficiency system—Active Mode, Transmission Mode, and Deep Sleep Mode—the Active Mode ensures efficient image acquisition and transmission. Transmission Mode streamlines power consumption by powering off the camera and putting the 4G module into DRX mode. Deep Sleep Mode retains only core components for operation. An ultra-low overall current of ≤150μA significantly extends battery life, and the 150μA standby current is 66% lower than similar products, supporting continuous operation for 365 days at a rate of 10 photos per day. Receiving cloud commands via the MQTT protocol, the wide wake-up cycle (1 minute to 24 hours) flexibly adapts to different monitoring frequencies without requiring on-site debugging. The camera module, 4G module, CPU, real-time clock, and interrupt controller are integrated onto the motherboard, resulting in a compact, highly efficient layout with rapid power consumption switching. This ensures effective monitoring while minimizing energy consumption, providing core support for long-term stable operation in unattended outdoor scenarios.
[0047] In some implementations, a QR code configuration module is also included. The QR code configuration module includes an identification code 20 disposed on the bottom of the casing 11, a terminal application 22, and a cloud configuration server 23. The identification code 20 contains an encrypted device unique identifier 21. The terminal application 22 obtains the device unique identifier 21 by scanning the identification code 20 and sends a binding request to the cloud configuration server 23. The cloud configuration server 23 pushes configuration parameters to the device through a 4G network and the MQTT protocol 19 to complete the initialization of the working mode.
[0048] The built-in encrypted unique identifier 21 of the identification code 20 effectively prevents unauthorized binding and information tampering, ensuring device configuration security. The terminal application 22 can obtain the identifier simply by scanning the code, eliminating the need for manual input; the operation is simple and intuitive, improving both convenience and security. Relying on 4G network and MQTT protocol 19, it eliminates the need for Bluetooth or Wi-Fi, enabling configuration even in areas with no signal coverage, overcoming environmental limitations. The cloud configuration server 23 remotely pushes configuration parameters and automatically initializes the working mode, eliminating the need for on-site debugging, significantly reducing device uptime and improving deployment efficiency.
[0049] In one specific embodiment, the identification code 20 is a QR code, the terminal application 22 is a WeChat mini program or a mobile APP, the configuration parameters include the setting of the shooting cycle and image resolution, the configuration process takes an average of ≤30 seconds, and the configuration process is analyzed by Wireshark packet capture.
[0050] By employing widely adopted QR codes as the device identification entry point, combined with familiar WeChat mini-programs or mobile apps as configuration tools, the learning and operation threshold for users is greatly reduced, achieving "scan and configure." The configured photo-taking cycle and image resolution are key operating parameters, directly affecting power consumption and image quality. The entire process takes an average of ≤30 seconds, significantly improving deployment efficiency. Support for network packet capture analysis using Wireshark means that the configured communication protocol is standardized and monitorable, providing a solid technical basis for protocol verification, fault diagnosis, and security analysis, ensuring the reliability and transparency of the configuration process.
[0051] In some implementations, the configuration process of the QR code configuration module includes:
[0052] S1: Terminal application 22 scans identification code 20 to obtain device unique identifier 21;
[0053] S2: The terminal application 22 sends the "device unique identifier 21 + user account" to the cloud configuration server 23 via the 4G network;
[0054] S3: After cloud configuration server 23 verifies user permissions, it pushes parameters such as photo cycle, image resolution and data upload frequency to the device.
[0055] S4: The device receives parameters and writes them to Flash storage, completing the initialization of the working mode.
[0056] Step S1 involves scanning a QR code to obtain the device's unique identifier 21, eliminating the need for manual input, simplifying the process, and preventing input errors. Step S2 relies on the 4G network for information transmission, eliminating the need for Bluetooth or Wi-Fi, enabling communication even in the absence of auxiliary signals in the field, overcoming environmental limitations. Step S3 involves the cloud configuration server 23 verifying user permissions to prevent unauthorized configuration, and allowing for customization of parameters such as the photo-taking cycle to adapt to different monitoring scenarios. Step S4 involves the device receiving parameters and writing them to Flash storage to complete the initialization of the working mode, eliminating the need for on-site debugging and significantly shortening deployment time. The entire process is interconnected, balancing security and practicality, and offering advantages such as high convenience, high security, and high flexibility.
[0057] In some embodiments, the outer shell 11 is integrally injection molded from a PC+ABS alloy (a plastic alloy composed of polycarbonate and acrylonitrile-butadiene-styrene blend).
[0058] By employing a PC+ABS alloy and a one-piece injection molding process, an optimized balance between performance and cost is achieved. The PC component endows the shell 11 with excellent rigidity, impact resistance, and high and low temperature resistance (typically -40℃ to 120℃), ensuring that it does not deform or crack in harsh outdoor environments. The ABS component enhances the material's toughness, flowability, and processability, enabling the precise molding of complex structures in a single step. The one-piece molding process completely eliminates seams, preventing water leakage at its source, greatly simplifying subsequent waterproofing assembly processes, and ensuring the overall structural strength and aesthetic consistency of the shell 11.
[0059] In some embodiments, the housing 11 has a battery compartment inside, the battery compartment is equipped with a battery, and the battery is electrically connected to the motherboard 9.
[0060] In one specific embodiment, the battery compartment is sealed by ultrasonic welding and has no external interface; the battery is a lithium thionyl chloride battery 8.
[0061] The battery compartment is sealed using ultrasonic welding, giving the device excellent dust and water resistance (e.g., IP67 rating), enabling it to withstand harsh outdoor environments such as rain and sandstorms for extended periods. The absence of any external interfaces also avoids malfunctions caused by interface oxidation, foreign object blockage, or human error during insertion and removal, significantly improving the overall reliability and durability of the device. The lithium thionyl chloride battery features high energy density, extremely low annual self-discharge rate (typically <1%), a wide operating temperature range (up to -55℃ to +85℃), and a long lifespan (up to 10 years or more). Combined, these characteristics allow the device to achieve complete physical sealing, eliminating the need for any external interfaces, while relying on the battery's ultra-low self-discharge rate and long lifespan to ensure stable operation for over a year even in harsh outdoor environments.
[0062] In some embodiments, a lens module 12 is provided inside the housing 11. The lens module 12 is electrically connected to the camera module. A butyl rubber sealing ring 13 is provided between the lens module 12 and the housing 11, and the protection level reaches IP67.
[0063] A static seal between the lens module 12 and the housing 11 is achieved by using a butyl rubber sealing ring 13. Butyl rubber has extremely low water vapor permeability, excellent elastic recovery, and resistance to environmental aging (ozone and UV radiation), maintaining its compression resilience over a long period and effectively coping with thermal expansion and contraction caused by outdoor temperature cycles. Its superior damping characteristics also help buffer minor vibrations. This ensures a durable and reliable full-circumference seal between the lens module 12 window and the housing 11, effectively preventing the intrusion of rainwater, dust, and moisture, protecting the internal precision optical components and camera circuitry for long-term stable operation in harsh outdoor environments, and fundamentally solving the common problems of water seepage and fogging in the lens area of surveillance equipment.
