CAMERA CONNECTION
Connect the coaxial cable (with pre-wired BNC
plug) to the BNC connector (Video) of the cam-
era.
If you are using an DC auto iris lens with the
camera, the lens has to be connected to the
DC-Iris socket of the camera. If you are using a
lens with manual or fixed iris, this socket is not
used.
The operating voltage is connected to the desig-
nated terminal block either 12VDC or 24VAC.
Operation of the camera will be confirmed by
the power LED at the rear side of the camera.
NTSC/PAL SELECT
NTSC/PAL should be set by the factory before it
is shipped to the customer.
On some models, NTSC or PAL can be selected
manually by moving the switch on the back of
the camera up or down (shown above).
NTSC - switch position is up
PAL - switch position is down
