IP Camera Video Inputs
The IP camera input capture rate is dependent on the resolution and quality of the images captured.
The IP cameras have a recommended maximum of 30 FPS per channel at 4CIF.
The 8704 S provides a capture rate of up to 3 mbps and 30 FPS per attached IP camera for 4
cameras (a total of 12 mbps of inbound traffic from 4 IP cameras).
