Dahua DH-AC-PFA134 Water proof Junction Box
Model: DH-AC-PFA134
Who This Is For
For installers who need a tidy, weatherproof solution for managing cable entries on outdoor Dahua camera installations, the PFA134 Waterproof Junction Box is a purpose-built mounting accessory designed to protect connections at the wall or ceiling surface. Constructed from aluminium and SECC steel, it provides a rigid, corrosion-resistant housing for cable terminations behind compatible Dahua cameras. The M20 (G1/2") thread entry accommodates standard conduit fittings, keeping the cable path sealed against moisture ingress. It suits wall and soffit-mounted installations where exposed cable tails or bare surface entries would be vulnerable to weather. At 90mm x 35mm, the PFA134 sits flush and low-profile behind the camera, maintaining a clean finish. It is rated across an operating temperature range of -40°C to +60°C, making it suitable for Australian outdoor conditions from alpine environments to exposed northern Queensland installations.
What This Junction Box Actually Does
Sealed Cable Entry
The M20 (G1/2") threaded port accepts standard conduit fittings, creating a sealed entry point for the camera cable. This eliminates the exposed cable tail at the mount surface that would otherwise be vulnerable to moisture, insects, and UV degradation over time.
Aluminium and SECC Construction
The combination of aluminium and SECC (Steel Electrolytic Cold Rolled Coil) gives the PFA134 structural rigidity without excessive weight. At 0.26kg, it adds minimal load to the mounting surface while supporting up to 1.0kg, covering the weight of most compatible Dahua camera heads.
Wide Temperature Range
Rated from -40°C to +60°C, the PFA134 handles extreme outdoor conditions. This range covers exposed rooftop installs in summer heat as well as cold-climate sites, without the housing warping, cracking, or losing its seal under thermal expansion and contraction.
Clean Finished Appearance
The white finish and compact 90mm x 35mm profile keep the install looking intentional rather than improvised. On rendered walls or painted soffits, the PFA134 sits behind the camera base with minimal visual intrusion, which matters on residential and commercial facades alike.
Who Buys This Model
- Security Installers: Professionals completing outdoor Dahua camera installations who need a compliant, weatherproof cable entry point rather than leaving a bare cable tail exposed at the mount.
- Electricians Working on CCTV Projects: Tradies running conduit to camera positions who require an M20 (G1/2") threaded interface to terminate the conduit run neatly at the camera base.
- Commercial Property Managers: Those coordinating camera upgrades or replacements on existing Dahua systems where replacing the junction box alongside the camera ensures a weatherproof, tidy result on the finished installation.
- DIY Installers on Outdoor Projects: Home or small business owners who have selected a compatible Dahua outdoor camera and want a proper cable management solution rather than exposed cabling at the wall surface.
Honest Assessment
The PFA134 does one specific job well: it provides a clean, weatherproof interface between the wall surface and the camera base, protecting the cable entry from moisture, insects, and UV exposure across a wide operating temperature range. The aluminium and SECC construction gives it enough durability for long-term outdoor use without adding meaningful weight to the installation. The M20 threaded port accommodates standard conduit fittings, which is a practical advantage on commercial sites where conduit runs are required. What it will not do is serve as a universal junction box for all cable types or sizes - you need to confirm your conduit fitting matches the M20 (G1/2") thread before ordering. It is also not an enclosure for splicing or terminating multiple cables; it functions as a surface adapter and cable entry seal, not an electrical junction box in the traditional sense. If your installation requires a larger cable management housing or a multi-port entry, a different accessory type would be more appropriate. The PFA134 is available through Security Australia as part of the Dahua accessories range.
Before You Buy
Installer Note: Confirm your conduit or cable gland uses an M20 (G1/2") thread before ordering. The PFA134 has a single threaded entry port at this size - if your cable run uses a different conduit diameter or a proprietary gland fitting, check compatibility before specifying this box. Also verify the camera model you are mounting is rated to 1.0kg or under, as that is the load bearing limit of the PFA134.
Colour Note: The PFA134 is available in white only. If the installation surface is a dark colour (charcoal render, dark brick, or black fascia), consider whether the white housing will be visually acceptable before ordering, as the box is visible behind the camera base.
Quick Fit Check
- Good match if: You are running conduit to an outdoor Dahua camera position and need an M20 (G1/2") threaded entry point at the mount surface to complete a weatherproof installation.
- Good match if: The installation is in an environment with significant temperature variation - the -40°C to +60°C operating range means this box holds up in harsh outdoor conditions without degrading the cable seal.
- You may need a different model if: Your installation requires a larger cable entry, multiple conduit ports, or a full weatherproof enclosure for cable splicing - in those cases, a dedicated outdoor cable enclosure or larger junction box type would be more suitable.
Key Features & Technical Specifications
Real-World Scenarios
How It Compares
- Choose this if: Your conduit or cable gland uses an M20 (G1/2") thread and you need a compact, low-profile weatherproof entry point behind a compatible Dahua camera on a wall or soffit surface.
- You may need a different model if: Your installation requires a larger cable management enclosure, multiple cable entries, or a full IP-rated outdoor enclosure for cable splicing - a dedicated weatherproof outdoor enclosure type would better suit those requirements.
- Pairs well with: Compatible Dahua outdoor turret, bullet, or dome cameras, along with M20 cable glands or conduit fittings to complete a fully sealed outdoor cable run.
Common Questions
-
Will the PFA134 fit any Dahua outdoor camera?
Not universally - compatibility depends on the camera's base footprint and mounting pattern. The PFA134 is designed for compatible Dahua camera models, so confirm your specific camera model is listed as compatible before ordering. The load bearing limit of 1.0kg also means it suits standard-weight outdoor cameras rather than heavy multi-sensor or large PTZ heads. -
What conduit size fits the PFA134 entry port?
The PFA134 uses an M20 (G1/2") threaded port. This is a standard conduit thread size that accepts M20 cable glands and compatible conduit fittings widely available from electrical suppliers in Australia. If your conduit run uses a different thread size, this junction box will not be compatible without an adapter fitting. -
Is the PFA134 suitable for outdoor use in Queensland or Northern Australia?
Yes. The operating temperature range of -40°C to +60°C covers the high ambient temperatures experienced in exposed outdoor installations in northern Australia. The aluminium and SECC construction also resists the UV degradation that affects plastic housings in high-UV environments over time. -
Does the PFA134 have an IP weatherproof rating?
An IP rating is not listed in the confirmed specification data for the PFA134. The product is described as waterproof and is designed for outdoor cable entry protection, but if a specific IP ingress protection rating is a compliance requirement for your project, contact Security Australia to confirm before specifying this product. -
Can I use the PFA134 as a cable splice point or termination enclosure?
No. The PFA134 is a surface-mount junction box designed as a cable entry adapter at the camera base, not as an enclosure for splicing or terminating cables. It provides a single M20 threaded port to seal the cable entry behind the camera. For cable splicing or multi-cable termination outdoors, a separate weatherproof electrical enclosure is required. -
How much weight can the PFA134 support?
The PFA134 has a confirmed load bearing rating of 1.0kg (2.2lb). This covers most standard Dahua outdoor camera heads. If the camera you are mounting exceeds 1.0kg, the camera should be independently supported by its own wall bracket or mounting hardware rather than relying on the junction box to carry the load.
