Special Attention:

  • Screw Pack 1 (for base installation)

  • Screw Pack 3 (for Pattern E)

  • Screw Pack 4 (for Pattern H)

  • Screw Pack 2 (for other cameras)

Product Overview

product overview L1

Special Attention:

  • Cable Entries – Multiple entry points
    • 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, a key part of junction box wiring.
    • 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 – Connects the junction box cover (front plate) to the base, allowing it to hang during installation 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.
    • ⚠️ For heavy cameras (e.g., RLC-823 series), always support the camera by hand.

3. Installation Instructions
