Dahua DH-PFA135 Water proof Junction Box
- Sku: DH-PFA135
- Vendor: SecurityAustralia
When a clean, weatherproof cable entry point is the requirement, the DH-PFA135 junction box delivers a tidy solution for surface-mounting compatible Dahua dome and bullet cameras. Built from die-cast aluminium, it conceals cabling behind the camera and protects connections from moisture and dust. Rated for operating temperatures from -40°C to +60°C, it suits both indoor and demanding outdoor installs.
Why This Model
- Aluminium construction: Die-cast aluminium is significantly more rigid and weather-resistant than plastic alternatives, meaning the junction box holds up long-term in exposed outdoor locations.
- M20 (G1/2") thread inlet: The standardised conduit thread allows direct connection to rigid conduit runs, keeping cable entries sealed and eliminating the need for additional adapters on most installations.
- Compact 90 x 34mm footprint: The low-profile form sits neatly between wall and camera without creating an unsightly bulk, maintaining a professional finish on finished surfaces.

Product Overview
Model: DH-PFA135
Who This Is For
When a clean cable entry point and a weatherproof termination are priorities on an outdoor camera installation, the Dahua DH-PFA135 junction box solves a problem that installers run into constantly - exposed conduit entry points, moisture ingress at the wall, and untidy cable runs that undermine an otherwise professional finish. This compact aluminium junction box mounts between the wall surface and a compatible Dahua dome or eyeball camera, concealing the cabling and providing a weather-sealed connection point rated for outdoor use across a temperature range of -40°C to +60°C. It suits trades installing cameras on rendered brick, Colorbond cladding, or fibre cement sheeting where a surface-flush finish matters. The M20 (G1/2") thread accommodates standard conduit fittings, making it straightforward to run cable through the wall and into the camera bracket without any cabling exposed to the elements.
What This Actually Does
Weatherproof Cable Entry
The PFA135 seals the gap between the camera mount and the wall surface, preventing moisture, insects, and dust from entering through the cable penetration. Rated for operation in humidity up to 90% RH and temperatures as low as -40°C, it handles Australian coastal and alpine conditions without deteriorating.
Standard Conduit Compatibility
The M20 (G1/2") threaded entry accepts standard conduit fittings used in Australian electrical and security installations. This means the junction box integrates directly with existing conduit runs rather than requiring custom adapters or workarounds at the termination point.
Aluminium Construction
Cast aluminium construction gives the PFA135 structural durability without adding significant weight to the camera mount assembly. At 0.16 kg, the box itself adds minimal load, while the 1.0 kg load-bearing rating provides adequate support for the camera mounted above it.
Clean Installation Profile
At 90.0 mm x 34.1 mm with a white finish, the PFA135 sits flat against the wall surface and avoids the bulky appearance of exposed junction boxes or conduit elbows. On rendered or painted walls it blends into the background rather than drawing attention to the cable entry point.
Who Buys This Model
- Security installers on residential projects: Trades fitting Dahua dome or turret cameras to brick veneer, weatherboard, or rendered walls where a weather-sealed, flush cable exit is expected as standard.
- Commercial fitout installers: Electricians and security contractors running conduit to camera positions on warehouses, retail tenancies, or commercial buildings who need a code-compliant, tidy termination at the camera bracket.
- Builders and project managers: Construction teams specifying camera infrastructure during the build stage, where conduit is already roughed-in and a matching junction box needs to be specified alongside the camera.
- DIY installers with conduit runs: Property owners who have run conduit through an external wall and need a proper termination point rather than relying on foam filler or silicone alone to seal the cable penetration.
Honest Assessment
The DH-PFA135 does one job well: it provides a weatherproof, structurally sound cable termination point between an external wall and a compatible Dahua camera mount. The aluminium construction, M20 conduit thread, and -40°C to +60°C operating range mean it performs in Australian outdoor environments without warping, cracking, or allowing moisture ingress at the cable entry point. The compact 90.0 mm x 34.1 mm footprint and white finish keep the installation looking deliberate rather than improvised. What it will not do is serve as a universal bracket or fit camera models outside its compatibility range - confirming fitment with your specific camera model before ordering is essential. It is also not a replacement for proper wall penetration sealing; silicone around the mounting face is still required. The PFA135 is supplied by Security Australia as part of the Dahua accessories range, alongside mounting arms, pole mounts, and power supplies for complete installation planning.
Before You Buy
Installer Note: The PFA135 has a load-bearing rating of 1.0 kg - confirm the total weight of your camera and any additional bracket before specifying this box on heavier PTZ or multi-sensor camera installations, as those typically require a dedicated wall mount rated for higher loads. For standard Dahua dome and turret cameras, the 1.0 kg rating is generally sufficient.
Conduit Sizing: The single M20 (G1/2") threaded entry is sized for standard M20 conduit fittings. If your cable run uses a different conduit size, check that an appropriate adapter is available before installation. Running oversized cable through M20 without a proper gland fitting will compromise the weatherproof performance of the assembly.
Quick Fit Check
- Good match if: You are mounting a compatible Dahua dome or turret camera on an external wall with a conduit cable run and need a weather-sealed, flush-fitting termination point at the camera position.
- Good match if: Your installation requires a tidy, professional finish on rendered, painted, or clad surfaces where an exposed cable entry would be visually unacceptable to the client.
- You may need a different model if: You are mounting a heavier PTZ or multi-sensor camera that exceeds the 1.0 kg load-bearing rating - a dedicated heavy-duty wall bracket or pole mount from the Dahua accessories range would be more appropriate for those applications.
Key Features & Technical Specifications
Real-World Scenarios
How It Compares
- Choose this if: You need a Dahua-matched, aluminium junction box for outdoor camera positions where a conduit cable run terminates at the wall and a weather-sealed, flush finish is required.
- You may need a different model if: Your camera requires a mount with a higher load-bearing capacity - Dahua's range includes heavy-duty wall brackets and pole mount adapters designed for larger PTZ and multi-sensor camera installations where 1.0 kg is insufficient.
- Pairs well with: Dahua dome, turret, or eyeball cameras that share the same mounting footprint, used alongside a compatible PoE switch and Cat6 cabling for a complete conduit-run installation.
Common Questions
-
Will this junction box work with any Dahua camera, or only specific models?
Compatibility is model-specific. The PFA135 is designed as a Dahua accessory with a defined mounting footprint - it is intended for compatible Dahua dome and turret camera models that share the same base diameter and screw pattern. Checking the accessory compatibility list for your specific camera model before ordering will confirm fitment and avoid a return trip to site. -
Does the PFA135 provide weatherproofing on its own, or does it still need sealing?
The junction box provides a structured, weather-resistant cable entry point, but silicone sealing around the mounting face where it meets the wall surface is still recommended. The M20 threaded conduit entry accommodates a cable gland or fitting, but the junction box itself should be treated as one component of a properly sealed outdoor installation rather than a standalone weatherproofing solution. -
What conduit size does the M20 thread accept?
The PFA135 uses an M20 (G1/2") threaded entry. This is compatible with standard M20 metric conduit fittings and G1/2" conduit adapters commonly used in Australian electrical and security installations. If your conduit run uses a different diameter, a conduit reducer or adapter fitting will be required to maintain a weatherproof seal at the entry point. -
Is the 1.0 kg load-bearing rating sufficient for a typical outdoor camera?
Yes, for most standard Dahua dome and turret cameras. The majority of Dahua outdoor dome and turret models weigh well under 1.0 kg, so the PFA135 load-bearing rating covers typical installations comfortably. For larger cameras such as multi-sensor units or motorised zoom models, checking the camera's weight specification against the 1.0 kg rating is advisable before specifying this junction box. -
Does this junction box suit Australian temperature conditions, including alpine and far-north Queensland climates?
Yes. The confirmed operating temperature range of -40°C to +60°C covers both alpine winter conditions in Victoria and Tasmania and the high ambient temperatures experienced in northern Queensland and outback areas. The aluminium construction also performs better than plastic in sustained high-heat environments where some plastic housings can distort over time. Security Australia stocks this accessory as part of the broader Dahua mounting hardware range for exactly these kinds of varied Australian installation environments. -
Can this junction box be used with non-Dahua cameras from other brands?
Not reliably. The PFA135 is engineered to the mounting dimensions of compatible Dahua cameras. While the conduit entry thread is a standard M20 size, the camera mounting interface - screw pattern and base footprint - is specific to Dahua models. Using it with a different brand's camera would require the camera's base to physically match the Dahua mounting pattern, which is unlikely without modification.
