Test on camera delay problems
Today, the monitoring of products into the Internet era, vision of the world brand camera has achieved high-definition monitoring effect, in addition to the front of the network surveillance cameras, the video transmission and back-end storage, display process must also be carefully designed, how to achieve high quality , No delay effect is the current monitoring application focused on solving the problem
Under normal circumstances, the ideal monitoring camera delay in 200ms or so, slightly worse IPC delay in more than 400ms. If the delay of the network camera to reach more than 400ms, you need to consider the serious delay phenomenon for the front-end equipment alarm.
Test the network infrared camera delay problem is very simple, only need to monitor the camera at high precision stopwatch, so that the reality of the image and display the image contrast, through multiple arrests we can calculate the IPC delay time.
