Housing and Mounting
All camera models feature a durable aluminum housing that minimizes fire hazards. The housing is not hermetically
sealed. The camera is not to be used outdoors without appropriate protective enclosures.
Cameras are mounted using a ¼” x 20 threaded hole at the bottom of the housing. When mounting the camera make
sure the screw that goes into the hole is short, ¼” or less, and does not touch the camera board.
The camera is to be installed according to the applicable code. The mounting means should be adequate for mounting
a 1 lb camera.
Network Cabling
Category 5 cabling or better is recommended. All network cabling must be installed according to applicable codes and
regulations by a licensed network cabling professional.
Optics
AV2100 and AV3100 can be used with a manual or DC ½” auto-iris lens. AV3130 requires two manual iris lenses and
has a limitation on lenses size. The lens mount can be C or CS with an appropriate adapter.
Using a Manual Iris Lens
Using a lens correctly is very important for mega-pixel cameras. The image may look blurry when the lens iris is fully
open or closed too much. To deliver sharp mega-pixel resolution images you should
a) use a mega-pixel-resolution lens
b) obtain best resolution and depth of focus by having the iris slightly closed
You should use a manual iris lens whenever possible. When setting up the camera, direct the camera at the scene and
try closing the iris in the manual lens by several F-stops. At some point you will see that the image looks sharpest.
Leave the iris closed at this value.
Using an Auto-Iris Lens
AV2100 and AV3100 are available with DC auto-iris option. To use a DC auto-iris lens:
1. Attach it to the camera
2. Plug in the lens cable into the connector on the back of the camera. Make sure the lens cable is long enough.
Many DC lenses are available with a short and long cable options.
The camera will automatically detect the presence of an auto-iris DC lens and start using it. Auto-iris lens operation
typically proceeds as follows:
1. If illumination is sufficient, the camera will typically close the iris within half-a-minute
2. When the iris is closed, the image should become visibly sharper. As the iris is gradually closed the image
may fluctuate slightly
3. The camera will use iris to control exposure
