Camera Inputs
Cable: 75-Ohm Coaxial
Connectors: BNC
Auto Terminating: Yes
Passive Looping: Yes
There are two BNC jacks for each camera. Either
jack can receive a camera signal. The signal is
looped (directly connected to the other jack), making
the camera signal available to other equipment.
The camera input connectors are Auto Terminating.
This means that the input signal will automatically be terminated with 75-Ohms unless a 2 nd cable is
connected to the 2
nd
BNC connector of the same camera input. Make sure there is 75-Ohm
termination at the end of the video line if the signal is looped through StoreSafe.
Time base correction is performed during digital capture. As a result, cameras do not require
synchronization.
See section 3.13 for information about disabling unused camera jacks in the menu system.
