5.   Camera Installation

1.

Remove the dome from the 

housing base by loosening 

the captured screws on the 

dome.

2.

Connect the yellow video 

output connector to the 

video input port on your 

monitor/DVR. Connect the 

red power connector to 

your 12 V DC power 

source. Feed the cables 

into the hole in the 

mounting surface (such as 

a ceiling, see graphic).

3.

Install the housing base 

onto the mounting surface 

using the three mounting 

screws provided.

4.

Connect the local video 

output cable to the video 

output connector on the 

camera board, located 

behind the lens and gimbal. 

Connect the other end of 

the video connector to the 

monitor you will use while 

setting up the camera.

Note

The video output 

connector on the 

camera board is 

located next to the OSD 

menu controls that you 

can use to make 

configuration changes.

5.

While monitoring the 

camera picture on the monitor, adjust the camera position (orientation), zoom and 

focus settings (as described in the 

Camera Positioning, Zoom and Focus Adjustment

 

section).

6.

Using the connected monitor, make camera configuration changes through the OSD 

menus (see the 

Configuration Guide

 included with your camera for more 

information).

7.

Re-install the dome cover to the housing base by aligning the captured screws to the 

screw holes, and then tightening the screws.

6.   Camera Positioning, Zoom and Focus Adjustment

1.

With the dome removed, you can see that the lens is surrounded by a protective 

shroud (see the image below).

2.

Use two hands to draw back the shroud from the lens by placing both thumbs on the 

upper front section of the shroud with your fingers bracing the back side of the lens 

and pushing your thumbs towards your fingers (see the image below).

3.

Position the camera lens and gimbal so that the camera is viewing the required video 

scene. Use the connected monitor to check that the field of view is oriented correctly 

as you make the adjustments. You can pan the entire camera board and gimbal 

(360°, labeled 

A

 in graphic above). Tilt the camera lens up and down (90°, labeled 

B

), 

and/or rotate the lens (360°, 

C

).

4.

Use the three points of 

adjustment (

A

B

, and 

C

) to 

position the camera 

correctly.

5.

Use the two levers located 

on the lens to adjust zoom 

and focus, as needed (see 

the image for zoom and 

focus lever locations).

6.

When the camera is 

correctly positioned, 

zoomed and focused, push 

the shroud back together 

with the lens.

When you push the shroud back together with the lens, this will change the tilt angle that you 

have set for the lens (adjustment labeled 

B

). When the shroud and lens are snapped back 

together, tilt both pieces back to the desired lens position.
