3.2.2 Video/Audio connection

1. Camera

Up to 16(SVR-950: Up to 9) CCTV cameras can be connected to DVR.
Connect the BNC terminal for each camera to the CAMERA IN terminal in the back of this product.
If BNC terminal is only connected to CAMERA IN, a 75 terminating resistor is
setup internally.
If connected to both CAMERA IN and CAMERA OUT, the device receiving the
output must setup a te rminating resi stor of 75.
Since CAMERA OUT terminal is a loop output for the camera input, it should only
be connected and used when there is an image input in CAMERA IN terminal.
If cable connected to the CAMERA OUT terminal is not connected to an external
device and is left exposed, image quality may be adversely affected.
Input video system type (NTSC/PAL) is recognized automatically when the
product power button is pushed. However, if a CCTV using a different system type
is connected to a CAMERA IN terminal during product operation, the product
must be turned OFF and ON again for proper automatic recognition of the input
video system type .
