CVBS OUT (Optional Secondary Output)

The yellow CVBS OUT connector provides a secondary analog 

output for the camera. 

It is not compatible with HD-SDI 

DVRs.

 

It can be used to connect the camera to a secondary CCTV monitor 

or non-HD-SDI DVR via BNC or to a TV using an RCA to BNC 

adapter (Lorex model # BNCB).  Output from the CVBS connector is 

not in HD.

Example scenarios using the CVBS OUT connector:

• 

Secondary BNC monitor to test camera image during installation.

• 

Secondary TV or CCTV monitor used as a public display monitor.

• 

Secondary non-HD-SDI DVR used as a backup recorder.

Before installing the camera:

• 

Decide whether to run the 

cables through the wall / 

ceiling (drilling required) or 

along the wall / celing.

• 

If you run the cables along 

the wall / ceiling, you must 

run the cable through the 

cable notch on the base. This 

will keep the camera base 

flush to the wall / ceiling 

when mounted.

or ceiling.

2.  If you are running the cables along the wall / 

ceiling, run the cable through the cable notch 

on the base. If you are running the cables 

through the wall, connect the power and black 

HD-SDI OUT video cable according to the 

section ‘Connecting the Camera.’

3.  Mount the camera to the wall or ceiling using 

the included mounting screws.

4.  Loosen the camera stand screws using the 

included allen key. Loosen the adjustment 

ring.

5.  Move the camera to the desired position, 

and while holding it firmly in place, turn the 

adjustment ring on the camera stand clockwise 

to tighten. Tighten the screws on the camera 

stand.
