Ensuring Accurate Person and Vehicle Detection
The following are important camera installation notes to ensure accurate person and vehicle detection. For full camera mounting instructions, see your camera’s documentation at lorex.com.
- 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.

Lower accuracy for objects further away than 50ft (~15m) and/or in the top ⅓ of the image.
Optimal accuracy for objects within 50ft (~15m) and in the bottom ⅔ 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.
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.
Additional Installation Tips
- Point the camera where there is the least amount of obstructions (e.g., tree branches).
- Install the camera that 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.

Installing the Cameras
ATTENTION – Test each camera prior to selecting a permanent mounting location by temporarily connecting the camera(s) and cables to the DVR.
Before installing the cameras:
- 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 the cameras:
- Set the camera in the desired mounting position and mark holes for screws through the camera base.
- Drill the holes, then feed the cable through the mounting surface or cable notch.
NOTE: Insert the included drywall anchors if installing the camera in drywall. - Mount the camera stand to the surface using the provided screws. Make sure all screws are fastened tightly.

Adjusting the Camera 
- Rotating the arm:
Loosen the adjustment ring between the camera arm and base by turning the ring counter-clockwise. Rotate the arm of the camera (up to 360°). When the arm is in the position you want, tighten the adjustment ring against the base by turning the ring clockwise. - Bending the arm:
Use a Phillips head screwdriver (not included) to loosen the adjustment screw. Bend the arm of the camera to the position you want (up to 90°). Tighten the screw.
- Rotating the camera:
Use the screwdriver to loosen the adjustment screw. Rotate the camera to the position you want (up to 360°). Tighten the screw.
Connecting the Cameras
- Connect the BNC and power connectors to the camera.
- Connect the BNC connector to the video input of your DVR.
- Connect the power connectors to the power adapter.
Power Adapter Types
A multi-camera power adapter that provides power to multiple cameras or individual power adapters may be provided, depending on product configuration.
Setup Diagram
ATTENTION
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.
