Mounting junction box DAHUA PFA137 for security cameras, model PFA137-BLACK

DAHUA PFA137 junction box is designed to provide a protected and orderly mounting point for security camera cabling and connections. The PFA137-BLACK version is a compact accessory that pairs with compatible DAHUA camera housings and mounts to hide and secure power, network and signal wires. It is suitable for indoor and outdoor installations where a neat, weather-aware connection point is required, helping to reduce exposure of connectors and extend the service life of installed equipment.

Advantages

The junction box offers a stable and tamper-conscious enclosure that organizes cable routing and protects terminations from direct moisture and mechanical stress. Its standardized shape and mounting holes make installation straightforward with many DAHUA mounts and housings, and the black finish provides visual discreteness for installations where appearance matters. The internal space accommodates typical power and network connectors and allows for cable entry from multiple directions.

Suitable for

• Outdoor surveillance camera installations requiring protected cable terminations
• Indoor camera deployments where cables must be concealed and secured
• Integration with DAHUA camera housings and wall or pole mounts
• Replacement or upgrade of existing junction boxes to improve weather resistance

Key specifications

• Material: durable, weather-resistant construction suitable for exterior use
• Color: black finish for reduced visual impact
• Internal space: accommodates standard power and network connectors and cable splices
• Mounting: compatible mounting hole pattern for common camera mounts and housings
• Cable entry: provision for multiple cable entry directions to support flexible routing

How to use

Mount the junction box to a wall, ceiling or pole using the recommended screws and anchors for the mounting surface. Route camera power and network cables into the box through the appropriate entry points, secure connections or splice points inside the enclosure, and fasten the camera or housing onto the junction box according to the camera manufacturer’s mounting instructions. Ensure seals and gaskets are properly seated to maintain weather resistance and verify that cable bends meet the minimum bend radius recommended for each cable type.

Usage recommendations

Use corrosion-resistant fasteners for outdoor installations and apply appropriate sealing compound around cable entries if additional moisture protection is required. Inspect the enclosure and cable entries periodically to ensure seals remain intact and that connectors show no signs of corrosion or mechanical wear.
