Installing the Camera

ATTENTION:

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

.

Cable Notch

To install your camera:

1. Use the included mounting template to mark holes for the screws.

Drill holes for the mounting screws.

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

camera in drywall.

4. Use a Philips screwdriver
(not included) to loosen the
adjustment screw.

5. Adjust the camera
position as needed:

6. Tighten the adjustment screw
to secure the position.

• You can use a RJ45 coupler or switch (not included) to connect male
ends of Ethernet cable together.

• To extend the cable run beyond 300ft (92m), a switch will be required
(sold separately).

Extend the Ethernet cable run for your camera up to 300ft (92m).
See table below. It is recommended to use UL CMR approved cables
available at lorex.com.

Problem Solution

No picture / signal • Ensure the camera is connected to a compatible

NVR supporting 4K camera input. For full camera
compatibility, visit

lorex.com/compatibility.

• The camera may take up to 1 minute to power up
after being connected to the NVR. Wait two minutes
before following the steps below.

• Ensure the camera is connected to your NVR or to
your local network.

• If you are not using PoE, you must connect the
camera to a 12V DC power adapter (not included).

• If the camera is connected to the LAN, you must
search your network for cameras using the NVR. See
the NVR’s instruction manual.

• Ensure your NVR is properly connected to a TV/
monitor.

• There may be an issue with your extension cable run.
Connect the camera to the NVR using a different
Ethernet cable.

Picture is too
bright

• Ensure your camera isn’t pointed directly at a
source of light (e.g., sun or spot light).

• Slide the sunshade forward to block excess light.

• Move your camera to a different location.

• Check the brightness and contrast settings on the
NVR.

Picture is too dark • If using during the day, the camera may not be

getting enough light. Slide the sunshade backwards
to let in more light.

• Check the brightness and contrast settings on the
NVR.

viewing camera at
night

• Night vision reflects when pointing a camera through
a window. Move the camera to a different location.

extra sensitive to light, meaning that the camera
stays in color mode at low-light conditions. For
instructions on how to make your camera switch to
night mode, visit lorex.com, and search for “How do I
make my camera switch to night mode?”.

RJ45 Cable Gland

Using the RJ45 Cable Gland (Optional)

The RJ45 cable gland is pre-attached to the

provide weather-resistance and protection from dust, dirt and other environmental
contaminants.

To use the RJ45 cable gland:

RJ45 Cable
Gland Barrel
