SAFEGUARDS & WARNINGS
1. Read instructions before
operating camera.
2. Avoid mounting in direct sunlight.
3. Installation and repair should be
undertaken by authorized personnel
only.
INSTALLATION TIPS
If the camera is to be mounted
outdoors, or in hot, humid, or otherwise harsh
environments, a secondary enclosure should be
used.
BACKFOCUS ADJUSTMENT
Manual Lens
1. If your camera has a lens on it already
chances are that is was pre-backfocused from
the factory. If not, screw the lens into the ring
on the front of the camera until it is fairly snug.
If the lens is varifocal bring it to the point
where it has the widest field of view (far). If
you are looking at objects close up adjust the
lens in the (near) distance not (far).
2. Loosen the two allen screws behind the CS
ring.
3. Backfocus the lens from the CCD until the
picture appears to be in focus.
4. If the lens has a focus ring, adjust that ring
to get your image in clear focus. Now tighten
the two allen screws so the lens does not come
loose.
DC Iris Lens
1. Perform the same functions as above Manual
Lens.
2. Make sure you plug in the DC Iris connector.
3. It is a good idea the check the lens perform-
ance under different lighting conditions.
CONTROLS / CONNECTORS
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
