What does the term “latency” refer to in video surveillance?

The term “latency” in video surveillance refers to the time delay between capturing video and viewing it. This delay can be critical in various surveillance applications, particularly in scenarios that require real-time monitoring and response. For instance, in security settings, any significant latency can hinder an operator's ability to react promptly to events as they unfold. Understanding latency helps in the system's design and analysis, especially when optimizing for performance in live video feeds.

The other options focus on different aspects of video quality and processing. The resolution pertains to the detail level in the video, which affects clarity but not delay. The amount of data processed relates to bandwidth and storage needs, which deals with performance but not the delay experienced by the user. Finally, color accuracy concerns the fidelity of color reproduction in the images captured, impacting the quality of visuals but not the time delay involved in the video stream.
