Junction box Dahua Technology PFA137

The Dahua Technology PFA137 Junction Box is a compact mounting accessory designed for CCTV camera installations. It provides a neat enclosure for cable connections and a stable mounting interface for compatible security cameras. The junction box supports cameras up to 1 kg, uses a 1/2" connecting thread and is finished in white to integrate with common indoor and outdoor installations. Its diameter is 12.2 cm and its height is 34.2 mm, while the unit weight is approximately 240 g.

Advantages

The junction box offers a compact, low-profile solution that organizes cable terminations and secures camera mounts without adding significant bulk. Its metal/plastic construction provides sufficient rigidity for light cameras up to 1 kg, and the standardized 1/2" connecting thread ensures compatibility with a wide range of Dahua and industry-standard mounts. The white finish helps the unit blend with façades and ceilings, while the moderate diameter and shallow height reduce visual impact.

How to use

Mount the junction box to a suitable flat surface using appropriate fasteners for the substrate (anchors or screws not included). Route camera power and data cables into the junction box through the entry points or knockouts, secure cable connections inside the enclosure, and attach the camera to the junction box using the 1/2" thread. Ensure the combined weight of the camera and any accessories does not exceed 1 kg. Tighten the camera mounting securely and verify the camera alignment before finalizing the installation.

Usage recommendations

Use corrosion-resistant fasteners for outdoor or high-humidity installations and seal any exposed cable entry points with appropriate weatherproofing to maintain enclosure protection. Confirm compatibility of camera base and mounting thread before installation and avoid exceeding the specified 1 kg weight limit to ensure stable, long-term attachment.
