What are some general camera installation tips?

Test cameras before permanent installation.

Plan wiring routes away from power/telephone lines and secure cabling.

Point cameras where there are minimal obstructions (e.g., tree branches).

Mount cameras away from direct/intense sunlight.

Mount cameras in visible but out-of-reach areas.

Avoid pointing cameras through glass windows (IR LEDs may reflect).

Adjust the angle to cover high-traffic areas.

Use multiple cameras in high-risk locations for redundancy.

For outdoor-rated cameras, sheltered installation is recommended to keep the lens clear.


How can I ensure accurate Person/Vehicle detection?

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

Angle the camera so objects of interest appear in the bottom 2/3 of the camera image.

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

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

Note: Accuracy depends on distance, object size, height, and camera angle. Night vision also affects accuracy. Counter/table top mounting is not recommended for Person/Vehicle detection accuracy.


How do I install the cameras?

1. Mount the cameras to the desired surface according to the camera-specific instructions (refer to lorex.com). Choose a firm surface that can support the camera’s weight. Use included drywall anchors if mounting on drywall.

2. Adjust the camera stand for a satisfactory view. Configure the stand based on the mounting surface (e.g., Wall Mount, Ceiling Mount).


How do I connect camera extension cables?

Note: Use a single stretch of cable between recorder and camera; do not connect multiple extension cables together. Check lorex.com for cable options and maximum lengths.
