The following default settings are assigned to cameras that are connected to the SVR-1670.
· Video input type, which is determined by the device that is connected to the lowest channel number. For
example, if there are fi ve cameras connected to the SVR-1670 and the lowest channel number in use is
6, then the SVR-1670 will set the video input type to match the camera connected to channel 6.
· About Video In and Out Connections
The SVR-1670 uses the "Auto Terminating Resistance" setting for the video input and loop output connections.
If the BNC terminal is connected only for video inputs, the terminal resistance is automatically set to 75Ω.
If the terminal is connected for both video inputs and loop outputs, the terminal resistance is set to Hi-Z;
you must confi gure the terminal resistance of the output device to 75Ω. The loop output terminal is only
for video inputs; use it only if there is video input to the BNC input terminal of a camera. Connecting an
end of a cable to the loop output terminal without connecting the other end to an external device may
cause degradation in video quality.
