Camera Layout

 

The camera can use a fixed iris, manual iris or auto iris lens. The camera is factory set for a CS-mount 
lens, but is easily adjusted for a C-mount lens. 

1.

 

 Rotate the back focus adjustment fully counterclockwise before 

installing the C-mount lens (refer to the section on 

 

).

2. Remove the cosmetic trim ring from the back of the camera (refer to Figure 1). Set the lens 

mode selector switch on the side of the camera to AIV (auto iris video drive lens) or AID (auto 
iris DC drive lens). Refer to the 

 

 section. Switch setting is determined by the 

type of lens used.

3. Screw the lens onto the lens mount. Be careful to prevent dust from entering the space 

between the lens and the CCD element. If necessary, use clean, compressed air to remove any 
foreign matter.

4. Thread the lens cable through the cosmetic trim ring.

5. Connect the auto iris lens to the four-pin connector located on the side of the camera.           

Pin connections for the iris drive connector are as follows:

NOTE:  The cosmetic 
trim ring conceals the 
LED light for more      
discreet surveillance 
operations. The trim 
ring also hides the 
power connectors and 
protects the DIP 
switches.
