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 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:

Lens Setup and Focus Procedures

Video Drive Auto Iris Lens

When a video drive auto iris lens is used, the lens mode selector switch must be set to AIV. Switch the ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video output level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) ﬁlter. Set the lens focus to inﬁnity (far). Select the scene to be viewed. Use the back focus adjustment ring (refer to the the selected scene. Remove the ND ﬁlter and set the lens focus as required.

Direct Drive (DC) Auto Iris Lens

Set the lens mode selector switch to AID. Switch the ESC ON. Use an appropriate screwdriver to turn the lens level potentiometer (refer to Figure 1) fully clockwise. Next, slowly adjust the potentiometer counterclockwise until the optimum picture is obtained (video output level of 1V peak-to-peak). To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) ﬁlter. Select the scene to be viewed. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens focus to inﬁnity (far). Use the back focus adjustment ring (refer to the the selected scene. Remove the ND ﬁlter and set the lens focus as required.

Fixed Lens

To focus, set the lens focus to inﬁnity and view an image greater than 6.5 feet (2 m) away. Focus the image with the back focus adjustment ring (refer to the focus as required.

Manual Iris Lens

To focus, open the iris fully and set the lens focus to inﬁnity. View an image greater than 6.5 feet (2 m) away. Focus the image with the back focus adjustment ring (refer to the section). Adjust the lens focus, set the iris for the best picture quality. The largest aperture gives the best light sensitivity, the smallest aperture the greatest depth of ﬁeld.

Zoom Lens

Set the lens focus to inﬁnity (far) and fully open the iris by covering the lens with a suitable neutral density (ND*) ﬁlter. Zoom out to the widest ﬁeld of vision and view a distant object. Adjust the back focus adjustment ring until the object is in focus (refer to the Next, zoom fully in and adjust the lens focus until the object is again focused. Repeat these steps until the full zoom range may be viewed with the minimum loss of focus.

* NOTE:

For best results in outdoor lighting situations use an ND3 ﬁlter to focus the camera.
