4-in-1 Power Splitter Cable

Connect a BNC-to-RCA Adapter (not included, Lorex model #
BNCB) to connect the extension cable to RCA inputs (i.e. for a TV
connection).

Before installing the camera:

• Decide whether to run the cables through the wall /
ceiling (drilling required) or along the wall / ceiling.

• 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.

To install the camera:

1. Set the camera in the desired mounting
position and mark holes for the screws.

2. Drill the holes, then feed the cable through the
mounting surface or cable notch and mount
the camera stand to the surface using the
provided screws. Make sure all three screws
are fastened tightly at the connection points.

Installing the Camera Cable Extension Options

Extend the cable run for your camera up to 300ft or more
depending on the cable type used. See table below:

Option Cable Type Max Cable

Run Distance

Max # of

Extensions

1 Regular BNC

(supplied with camera)

180ft / 55m 3

2 ‘RG59’ or ‘Coax’ or

‘Coaxial BNC’
(sold separately)

300ft / 92m 5

3 Lorex Universal Cable

(sold separately)

300ft / 92m 3

Notes:

1. For optimal performance, consider using option 2 or 3. It is best to use
the same cable type for the entire distance.

2. Cable run recommendation based on typical camera power consumption
(up to 500mA). For specialty cameras with higher current consumption,
maximum cable run may be reduced. Consider providing power to the
camera at the camera side, rather than at the end of the extension cable.

3. Indicators that your cable run may be too long:

• Video is permanently black & white (even during day time)

• Video is distorted

ATTENTION - Test all connections and ensure the camera is working

correctly prior to permanent installation by temporarily connecting the
camera(s) and cable(s) to the viewing / recording solution.

Problem Solution

No picture / signal • Ensure your TV is on the correct input channel.

Common terms of an input channel: INPUT, AV
