• For a full list of compatible recorders, visit lorex.com/compatibility.

• To ensure that you are viewing camera video in full 4K resolution (4K monitor required),
check the video output resolution of your recorder. For full instructions, see your recorder’s
documentation at lorex.com.

• Not intended for submersion in water. Installation in a sheltered location recommended.

• 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.

Disclaimers

ATTENTION:

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

• Review the section “STEP 1: Important Installation Guidelines” above before choosing a
permanent mounting location.

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.

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

3. Feed the cable through the mounting surface or cable notch and mount
the camera stand to the surface using the provided screws.

4. Use a Philips head screwdriver (not included) to loosen the adjustment
screws shown below. Adjust the camera position as needed:

A. Rotate the camera
base 360°.

B. Tilt the camera on
the stand up to 90°.

C. Twist the camera
around the stand 360°.

A B C

5. Tighten the adjustment screws to secure the position.

6. Remove the vinyl film from the camera lens when your installation is
complete.

Additional Installation Tips:

• Point the camera where there is the least amount of obstructions (e.g., 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.

STEP 1: Important Installation Guidelines

Optimizing Person and Vehicle Detection Accuracy:

• Angle the camera so that objects of interest appear in the bottom ⅔ of the camera
image.

• Choose a location where objects of interest will be no further than 50ft (~15m) from
the camera.

Optimal accuracy
for objects within
50ft (~15m) and in
the bottom ⅔ of the
image.

Lower accuracy for
objects further away
than 50ft (~15m) and/
or in the top ⅓ of the
image.

• Angle the camera between 30~60° down from the
level position.

• Install the camera between 8-16ft (2.5-5m) off of
the ground.

STEP 2: Installing the Camera

Level position (i.e., ceiling)

Optimal
angle
range

NOTE: Accuracy of person and vehicle detection will

be influenced by multiple factors, such as the object’s
distance from the camera, the size of the object, and
the height and angle of the camera. Night vision will
also impact the accuracy of detection.
