Installation of RLC-520A

Power on the Camera

You may power on Reolink PoE cameras via PoE injector/switch or PoE NVR directly, or by using the power adapter.

Method 1: Power via PoE Injector/Switch



Method 2: Power by PoE NVR
Connect your PoE camera to the PoE NVR by a single network cable, then the PoEcamera will get power via the PoE NVR.


Method 3: Power by Using the Power Adapter
Alternatively, you can power on the camera in another way – by using a power adapter.

For Reolink RLC-423/RLC-823A, the ratings of the power adapter should be DC 12V 2A.

For other Reolink PoE camera models, the ratings of the power adapter should be DC12V 2/1A.


  1. Do not purchase passive PoE injectors as they won’t work with Reolink PoE cameras.
  2. It's better to use high-quality PoE injectors/switches.
  3. We recommend that you purchase the Ethernet cable with Cat5 and above.
  4. Please install the waterproof lid at the junction of the Ethernet cable and the camera to protect the junction from water.
  5. Please note that the optimum distance between the camera and the PoE switch/Reolink NVR is 300 feet.

Mount the Camera

Please refer to the following steps to install the camera with the mount.

Step 1. Use the mounting hole template to drill mounting holes on the ceiling, and plant the rubber anchoring into the mounting holes.

Step 2. Screw the base panel to the mounting holes on the ceiling or wall.

It's suggested to install dome cameras on the ceiling usually.


Step 3. Fit the concave at the bottom of the camera (marked as 4,5,6 in the picture below) to the convex on the base panel (marked as 1,2,3 in the picture below), and then rotate the camera seating (marked as Part A) clockwise to lock the camera tightly with the base panel.

Note: To take down the camera, please rotate part A anti-clockwise.
Step 4. Once the camera is installed, you can adjust the angle up and down 70 degrees or 360 degrees horizontally.
