Sealed Spheroid Camera Remote Pan Tilt Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems, particularly mini-dome cameras, require manual adjustments for wall mounting to ensure the image is level with the ground, which involves opening the camera and can be cumbersome for scene changes or maintenance, and they often require analog video outputs for alignment, complicating remote control and sealing issues.
Innovation Solution
A camera system with a drive mechanism and processing circuit that allows remote pan and tilt control using magnetic or gear-based systems, enabling the camera to maintain a level image without manual adjustments, and eliminating the need for bubble covers by using sealed designs with magnetic levitation and digital image transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustments are made for wall mounting alignment, then image level alignment is achieved, but device complexity and ease of operation deteriorate due to opening the camera and analog video outputs
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated motorized pan-tilt mechanism. The processing circuit automatically controls the pan and tilt motors to level the image based on mounting orientation detection, eliminating the need for manual opening of the camera and analog video output alignment procedures.
Solution Approach 2:
The camera system performs self-leveling through automated detection of mounting orientation (wall or ceiling) and automatic adjustment of pan/tilt angles via the processing circuit. The system serves itself by automatically compensating for mounting position without requiring user intervention or manual alignment procedures.
2Measurement precision
If the camera is opened for manual adjustments, then alignment is possible, but reliability and sealing deteriorate
Solution Approach 1:
The patent replaces the mechanical opening/access mechanism with an automated electronic control system. The motorized pan-tilt mechanism and processing circuit enable alignment adjustments without physically opening the camera housing, maintaining the sealed environment and preventing contamination or damage to internal components.
3Measurement precision
If analog video outputs are used for alignment, then image level can be monitored, but device complexity and ease of operation worsen due to remote control limitations
Solution Approach 1:
The patent replaces analog video output monitoring with digital image processing and transmission. The processing circuit digitally processes images from the sensor module and transmits them via digital communication interfaces, enabling remote monitoring and control without the complexity of analog video cables and remote control hardware.
4Reliability
If bubble covers are used to maintain sealing, then camera sealing is maintained, but image quality deteriorates due to distortion
Solution Approach 1:
The patent extracts and eliminates the bubble cover component from the camera system. By using automated motorized pan-tilt mechanisms and digital processing, the system achieves alignment and sealing without requiring bubble covers, thereby eliminating the source of image distortion while maintaining protective sealing.

AI summary
A camera system includes a camera, a drive system, and a processing circuit. The camera includes a lens and a sensor module that receives light and outputs images based on the received light. The drive system includes a track including a first member and a second member, the first member defining a first rail on an inner surface of the first member, the second member defining a second rail on an outer surface of the second member. The rails can be driven by gear or magnetic drive, and are connected in a cross pattern at a 45 degree latitude point, enabling pan and tilt movement to maintain a level image for multiple camera mounting orientations.
