Installation

The Observer 4120 is shipped with a base containing an

integrated cooling fan. Ensure the cooling fan power

cable is connected to the cooling fan power port.

Remove the Security Cover and open the faceplate as

described on the following page. Secure the 4120 to a

flat surface using appropriate fasteners.

NOTE: Ensure that the front panel of the HVR remains

accessible, there is a minimum 2.5 inches of clearance for

cables, and there is adequate space to provide air for the

cooling fan. Do not install the HVR in an area of the vehicle

cabin that could interfere with the safe operation of the

vehicle.

Security Cover

After connecting all needed cables to the rear of the DVR

as shown in the Main Wiring Diagram, secure the Security

Cover with the included screws as shown in the diagram.
