Installing the Camera

Test your camera prior to selecting a permanent mounting location by
temporarily connecting the camera and cable to your NVR.

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 surface when mounted.

To install your camera:

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

screws through the camera base.

2. Drill the holes, then feed the cable through the mounting surface or

cable notch.

NOTE: Insert the included drywall anchors if you are mounting the

camera onto drywall.

3. Connect cables as shown in the section “Connecting the Camera”.

4. Mount the camera stand to the mounting surface using the provided

screws. Make sure all screws are fastened tightly.

5. Adjust the camera as shown below:

A B C

A. ROTATING THE ARM: Use the included Allen key to loosen the

adjustment screw closest to the camera base. Rotate the arm of the
camera as needed, then tighten the screw.

B. BENDING THE ARM: Use the Allen key to loosen the middle
adjustment screw. Bend the arm of the camera up to 90°, then
tighten the screw.

C. LEVELING THE CAMERA: Use the Allen key to loosen the
adjustment screw furthest from the camera base. Rotate the camera
until it is level with the viewing area, then tighten the screw.

This camera includes an Auto Mechanical IR Cut Filter. When the camera
changes between Day/Night viewing modes, an audible clicking noise may
be heard from the camera. This clicking is normal, and indicates that the
camera filter is working.

Installation Tips

• Point the camera where there is the least amount of obstructions (i.e., tree
branches).

• Install the camera where vandals cannot easily reach.

• Secure cabling so that it is not exposed or easily cut.

• This camera is rated for outdoor use. Installation in a sheltered location is
recommended.

Connecting the Camera

Ethernet Cable

Camera

Connect the other end of the
Ethernet cable to the NVR’s PoE
ports. The camera may take a
minute to power up after
being connected.

(Optional)

12V DC Power

Connect the Ethernet cable to
the camera.

NOTES:

• For weatherproofing instructions,
see “Using the Weatherproofing
Cap (Optional)”.

• A 12V DC power adapter (model#:
CVA4902, not included) is
only required if connecting the
camera’s Ethernet cable to a
router or switch that does not
support PoE.

Connecting the Cameras

Setup Diagram

Connect the other end of the
Ethernet cable to a router or
switch on your network. See
your NVR manual for details on
connecting the camera to your
NVR using a switch or router.

Scenario 2: Connect Cameras to Local Area Network (LAN)

Router

• This camera is only compatible with select NVRs. For a list of
compatible recorders, visit lorextechnology.com/compatibility.

• For the smoothest possible 4K video streaming experience,
connect your NVR to a Gigabit router (use available 1000Mbps /
1Gbps ethernet port). If you are connecting cameras to an external
network switch, it is recommended to use a 10/100/1000Mbps port
on a Gigabit network switch.

Using the Weatherproofing Cap (Optional)

O-Ring Rubber Stopper

Camera Ethernet Connector

1. Fit the O-ring around the camera Ethernet connector.

2. Feed the Ethernet extension cable through the end cap and the barrel as
shown above. Connect the cable to the camera Ethernet connector.

3. Twist the barrel securely onto the camera Ethernet connector. The o-ring
becomes compressed when the seal is properly tight.

4. Split the rubber stopper to wrap it around the cable between the barrel
and end cap as shown above. Push the rubber stoppper toward the barrel

until it is underneath the teeth at the end of the barrel.

5. Twist the end cap securely onto the barrel. The rubber stopper becomes
compressed and will stick out of the end cap slightly when the seal is
properly tight.
