Key Design Features

  • Cable Entries – Multiple entry points to simplify junction box wiring
    • Front Plate Entry: Equipped with a waterproof rubber grommet for the camera’s tail cable; the grommet can be temporarily removed to make cable threading easier during installation.
    • Side Entries: Two side entries on the base; one includes a removable cover that can be swapped with the cable gland (Comes with a waterproof rubber ring, removable for easier cable insertion.
      ) for waterproof protection.
    • Back Entry: An additional entry at the bottom of the base for more flexible cable routing.
  • Snap Hook Chain – for convenience and safety
    • Metal chain connecting the front plate to the base via a D-ring.
    • Allows you to hang the front plate (and attached camera) from the base during installation, freeing your hands for tools or ladder use.
    • Can be temporarily unhooked for greater adjustment flexibility.
    • Serves as a safety feature to prevent the cover and camera from falling when screws are loosened.

    Step 3: Mount the Junction Box Base

    1. Drill holes using the mounting template. Ensure the junction box is aligned with the camera angle.

    Important: Do not install the junction box base at the wrong angle.
    Since the camera bracket is fixed on the front plate, align the mounting template with your desired camera angle before drilling.

    Done! Now you can adjust the camera angle to achieve the best field of view. You may refer to How to Install Reolink Duo Series Camera

  • Pattern D: Install Reolink RLC-81PA Camera with Junction Box RLA-JBS1

    Step 1. Secure the camera to the front plate

    1. Prepare the junction box: Remove the screws on the front plate to separate the front plate from the base. Then, unscrew the cover of the cable gland.

    2. Feed the cable(s): Feed the network/power cable through the cable gland of the junction box. You can temporarily take the waterproof rubber grommet out of the cable gland to make it easier to thread the cable through. The rubber grommet of the cable gland can be opened along the slit to fit around the cable(s).

    3. Thread the tail cables: Take out the rubber grommet on the front plate. It has a slit that allows it to be opened to put the cables in. Then thread the cables of the camera through the cable entry on the front plate of the junction box.

    Then plug the rubber grommet back into the cable entry.

    4. Secure the camera: Secure the camera to the corresponding mounting Pattern-D on the junction box with the screws.

    Note:

    The base of the camera is approximately an isosceles trapezoid (not square), so each hole on the camera bracket corresponds to one specific hole on the front plate. 

    To help you quickly identify the correct orientation and hole, you can make the camera's adjustment knob positioned on the left side. Then, refer to the image below for a clear visual guide to match the corresponding holes.

    Step 2. Set up and mount the base of the junction box

    1. Drill holes: Attach the mounting template to an appropriate location on the wall/ceiling. Then drill holes according to the hole position on the sticker using a drill bit (not included).

    Important Note: The direction of the junction box base installation should not be decided arbitrarily.

    The camera is fixed at a specific angle on the front plate of the junction box, so the junction box must be installed at the corresponding angle to ensure proper alignment. If this is not taken into account, it may result in the camera being installed at an angle that is not what you intended.

    Therefore, before drilling the holes for the base of the junction box, check the camera angle you need, then attach the mounting template accordingly.

    Drill holes

    2. Mount the base: Mount the junction box to the wall/ceiling with the screws in the pack of screws of the junction box. If necessary, you can use the provided drywall anchors for additional support.

    Step 3. Secure the front plate

    1. Connect and organize the cables: Connect the power supply and the network cable according to your needs. Then tidy the cables and place them in the junction box.
