Video Camera Identification via Mobile Visual Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex video surveillance environments with multiple cameras, operators face difficulties in quickly identifying a specific camera due to similar-looking areas and inadequate naming conventions, leading to time-consuming manual searches.
Innovation Solution
A method and system where a mobile device outputs a visual identifier, such as a flashing light pattern, which is detected by cameras and transmitted to a server for identification, allowing the server to quickly determine the camera's identity and send this information back to the mobile device.

Engineering Contradiction Analysis
1Measurement precision
If operators manually search through multiple video streams to identify a camera, then they can locate the camera, but the process becomes time-consuming and cumbersome
Solution Approach 1:
A mobile device serves as an intermediary by emitting a visual identifier (flashing light pattern) that cameras capture. This mediator enables indirect identification - the operator doesn't need to manually examine video streams,而是 uses the mobile device to trigger and receive camera identification information automatically
Solution Approach 2:
The system implements feedback by having cameras capture the visual identifier from the mobile device, transmit the captured identifier back to the server, which then provides the camera identification information to the mobile device. This closed-loop feedback mechanism automatically completes the identification process
2Area of stationary object
If cameras are deployed in large numbers to cover complex surveillance areas, then coverage is improved, but the difficulty of identifying specific cameras increases
Solution Approach 1:
The mobile device with visual identifier acts as an intermediary that enables selective identification among numerous cameras. Instead of manually searching through many cameras, the operator uses the mobile device to automatically identify the specific camera in proximity, making the system scalable to large numbers of cameras without increasing identification difficulty
Solution Approach 2:
The camera system performs self-identification by automatically capturing the visual identifier from the mobile device and transmitting its own identification information back to the operator via the mobile device, eliminating the need for manual searching and reducing identification difficulty regardless of the number of cameras deployed

AI summary
Methods, systems, devices and computer readable media for identifying a video camera of a video surveillance system are provided. A plurality of video streams of a plurality of video cameras are obtained. At least one video camera of the plurality of video cameras captures a visual identifier outputted by a mobile device. The visual identifier is detected in at least one video stream of the plurality of video streams based on searching for the visual identifier in the plurality of video streams. The at least one video camera capturing the visual identifier is identified from the at least one video stream having the visual identifier detected therein. Identification information of the at least one video camera capturing the visual identifier is transmitted to the mobile device.
