Camera Tilt Sensor Self-Alignment Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of monitoring cameras is laborious due to the need for manual adjustments to achieve the correct tilt and leveling, which can be time-consuming and affect the concentration of the person monitoring the video.
Innovation Solution
A method that pre-calculates a predetermined tilt value during the design phase and stores it in the camera's memory, using a tilt sensor to generate a tilt value signal and indicating adjustments through a light emitting device or audio emitter, allowing for easier alignment of the camera to the correct tilt angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual adjustment of camera tilt and direction is performed by eye, then the camera can be installed without specialized equipment, but the installation process becomes laborious and time-consuming with repeated trips between camera and monitoring center
Solution Approach 1:
The system uses a tilt sensor to continuously monitor camera orientation and provides real-time feedback through visual indicators (LEDs) showing whether the camera is properly leveled. This closed-loop feedback eliminates the need for repeated trips to the monitoring center, as the installer can immediately see adjustment results at the camera location.
Solution Approach 2:
The camera system performs self-diagnosis of its own orientation using the integrated tilt sensor and provides self-feedback through onboard visual indicators. This eliminates the need for external monitoring equipment or additional personnel to check camera levelness, enabling the installer to independently complete the leveling task.
2Ease of operation
If a monitor is connected to the monitoring network closer to the camera for viewing, then real-time camera view can be checked during installation, but additional equipment and network infrastructure are required
Solution Approach 1:
The camera system uses its own tilt sensor and onboard visual indicators to provide installation assistance, eliminating the need for external monitors, computers, or additional network equipment. The camera essentially monitors and guides its own installation process.
Solution Approach 2:
The monitoring function is extracted from the centralized monitoring center and placed directly at the camera location through the tilt sensor and visual indicators. This allows installation feedback to be obtained locally without requiring connection to distant monitoring equipment.
3Manufacturing precision
If another person studies the monitor and reports to the installer, then accurate camera positioning can be achieved, but additional personnel and communication time are required
Solution Approach 1:
The camera system independently monitors its own orientation and provides direct visual feedback to the installer through onboard indicators. This eliminates the need for a second person to interpret monitor displays and communicate positioning status, as the feedback is immediately visible at the camera location.
Solution Approach 2:
The tilt sensor acts as an intermediary device that objectively measures camera orientation and translates it into intuitive visual signals. This mediator provides precise positioning information without requiring human interpretation or communication, reducing both personnel needs and communication overhead.
4Ease of operation
If specialized installation display or adaptor equipment is used, then camera leveling can be facilitated, but additional specialized equipment and cost are required
Solution Approach 1:
The tilt sensor and visual indication system are integrated directly into the camera housing, merging the leveling function with the camera itself. This eliminates the need for separate specialized installation displays or adaptors, as the camera becomes its own installation aid.
Solution Approach 2:
The camera system serves dual functions: it performs both monitoring and self-installation assistance. The same camera that will capture surveillance footage also contains the tilt sensor and indicators needed for installation, eliminating the need for dedicated installation equipment.
