Dahua DH-PFA136 Water-Proof Junction Box

Model: DH-PFA136

Who This Is For

When a clean, weatherproof cable termination point is the priority, the Dahua PFA136 junction box is the installer's go-to finishing piece. Designed for outdoor camera installations where exposed cable entries would otherwise be vulnerable to moisture ingress, wind-driven rain, and temperature extremes, this aluminium junction box provides a tidy and durable housing for the cable connection behind compatible Dahua cameras. It suits residential eave mounts, commercial fascia runs, and any outdoor installation where protecting the cable entry from a -40 degrees C to +60 degrees C operating range is a genuine requirement. Electricians and CCTV installers who take a professional approach to conduit termination and cable management will find this a straightforward addition to their camera install kit. Its compact 110 x 34 mm footprint keeps the profile low against the mounting surface, and the white aluminium finish blends with standard fascia colours.

What This Actually Does

Who Buys This Model

• CCTV Installers: Specifying a proper conduit termination behind outdoor bullet or turret cameras where the cable exit point needs to be enclosed and protected before the camera mounts over it.
• Electricians Managing Cable Runs: Bringing conduit runs to a termination point on eaves or rendered walls where a gland-to-box connection keeps the install compliant and weather-sealed.
• DIY Installers Finishing a Dahua System: Adding junction boxes to existing outdoor camera installations where the cable entry was previously exposed or taped, to improve long-term weatherproofing.
• Commercial Project Specifiers: Including junction boxes in camera BOMs as a standard line item to ensure a consistent, professional finish across multi-camera outdoor deployments.

Honest Assessment

The PFA136 does one job and does it correctly: it gives the cable connection point behind an outdoor camera a sealed, durable housing that stands up to the weather without adding bulk. The aluminium build and wide temperature rating make it more durable than generic plastic junction boxes sold at hardware stores, and the M20 thread is a practical compatibility point for standard conduit accessories. At 190 grams and a 1 kg load-bearing rating, this is a light-duty mounting accessory, not a structural bracket - the camera's wall or ceiling mount still carries the camera weight. It will not add an IP rating to a camera that does not already have one, and it is not a universal fit for every Dahua model - check mount compatibility before ordering. Available through Security Australia as part of a full Dahua accessory range for pairing with compatible outdoor cameras.

Before You Buy

Quick Fit Check

• Good match if: You are running conduit to an outdoor camera mount point and need a weatherproof, aluminium-bodied termination box that accepts a standard M20 cable gland or conduit fitting.
• Good match if: Your installation is exposed to extreme temperatures - the -40 degrees C to +60 degrees C rating covers alpine, coastal, and rooftop environments where plastic accessories fail over time.
• You may need a different model if: Your camera requires a larger junction box with more internal volume for connector splicing - look at Dahua's larger PFA-series enclosures for installations with multiple cable terminations or larger connector assemblies.

Real-World Scenarios

How It Compares

• Choose this if: You need a compact, aluminium weatherproof junction box for a conduit-terminated outdoor camera install with a standard M20 cable gland connection.
• You may need a different model if: Your installation requires a larger internal volume for multiple cable splices or connector assemblies - look at larger Dahua PFA-series enclosures better suited to higher cable density terminations.
• Pairs well with: Compatible Dahua outdoor bullet or turret cameras, standard M20 cable glands, and 20 mm rigid or flexible conduit systems for a complete conduit-terminated install.

Common Questions

1. Will the PFA136 fit all Dahua outdoor cameras?

   No. The PFA136 is designed for compatible Dahua camera models - not every Dahua outdoor camera uses this junction box. Check the accessory compatibility list for your specific camera model before ordering, as some models use different mount adapters or have integrated cable management that does not require a separate junction box.

2. Does this junction box include a cable gland?

   No. The PFA136 provides the M20 (G1/2") threaded entry point but does not include a cable gland in the package. You will need to source a compatible M20 cable gland separately to complete the weatherproof seal at the conduit or cable entry point.

3. Is this suitable for outdoor installation in Australian conditions?

   Yes. The confirmed operating temperature range of -40 degrees C to +60 degrees C and 0-90% RH humidity rating cover the full range of Australian outdoor conditions, from cold alpine environments to humid tropical climates and hot, dry inland regions. The aluminium construction does not degrade under UV exposure the way plastic housings can over time.

4. What conduit size does the M20 thread accept?

   The M20 thread corresponds to a G1/2" (half-inch) pipe thread, which is the standard size for 20 mm conduit fittings and cable glands widely used in Australian electrical and low-voltage installations. Standard M20 cable glands are available from electrical wholesalers and are compatible with this thread.

5. What is the maximum load this junction box can support?

   The confirmed load bearing rating is 1.0 kg. This means the PFA136 is a cable management and weather sealing accessory - it is not rated to carry the weight of the camera. The camera itself must be supported by its own wall or ceiling mounting bracket, independent of the junction box.

6. Does this junction box come in colours other than white?

   No. The confirmed colour for the DH-PFA136 is white. If your installation requires a different finish, check with Security Australia for alternative Dahua junction box or mounting accessory options that may suit your surface colour requirements.
