It includes motion detect, video loss and tampering.
Motion detect: After analyze video, device can generate a motion detect alarm when the
detected moving signal reached the sensitivity you set here.
Video loss: This function is to detect the input signal source status. When the input video
signal is loss (input port is loosen or there is no input signal), device can generate an alarm.
Tampering: When someone viciously masks the lens, or the output video is in one-color
due to the environments light change, the system can alert you to guarantee video
continuity.
Here we use motion detect interface to introduce.
From main menu->Event->Video detect->Motion detect, the motion detect interface is shown as in
