STEP 1: Important Installation Guidelines

Optimizing Person and Vehicle Detection Accuracy:
- Angle the camera so that objects of interest appear in the bottom 13 of the camera image.
- Choose a location where objects of interest will be no further than 50ft (\~15m) from the camera.

Thermal image showing a person walking on a rooftop with a car, surrounded by trees and buildings (no text or symbols visible)Lower accuracy for objects further away than 50ft (\~15m) and/or in the top 13 of the image.
Optimal accuracy for objects within 50ft (\~15m) and in the bottom 34 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.
Level position (i.e., ceiling)

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 2: Installing the Camera
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.

To install your camera:
- 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. - Connect cables as shown in the section "Connecting the Camera".
- Feed the cable through the mounting surface or cable notch and mount the camera stand to the surface using the provided screws.
- 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°.

- Tighten the adjustment screws to secure the position.
- Remove the vinyl film from the camera lens when your installation is complete.

Connect the Ethernet cable to the camera.
NOTE: A 12V DC power adapter (model#: ACCPWR12V1, not included) is only required if connecting the camera's Ethernet cable to a router or switch that does not support PoE.
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.

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.

Using the RJ45 Cable Gland [Optional]
The pre-attached RJ45 cable gland covers the camera's Ethernet connector and the RJ45 plug to provide weather-resistance and protection from dust, dirt and other environmental contaminants.
To use the RJ45 cable gland:
Twist the RJ45 cable gland barrel securely onto the camera Ethernet connector.
