Dahua DH-PFA139 Water-proof Junction Box

SKU: PFA139
Description

The Dahua DH-PFA139 is a compact aluminium junction box that mounts behind Dahua turret and eyeball cameras. It gives a tidy, sealed cavity to coil and protect the network cable and connector where it enters the camera, instead of leaving the join exposed on the wall.

01Overview

What the PFA139 is

The Dahua DH-PFA139 is a camera junction box for Dahua's turret and eyeball range. It lifts the camera slightly off the surface and creates a protected space for the network cable, connector and any pigtail, so the join is hidden and shielded rather than exposed on the wall.

It is machined from aluminium alloy with a white finish and measures Ø108.0 mm by 28.5 mm at about 0.16 kg, making it the compact box in Dahua's line-up. It uses an M20 (G1/2 inch) gland thread for the cable entry and is rated to a 1.0 kg load, comfortably more than the lightweight turret and eyeball cameras it carries.

Dahua does not publish a formal IP rating for this box; it is a weather-resistant aluminium housing that keeps the cable join dry once you seal the entry. As compatibility is set by the camera's mounting pattern, always confirm the DH-PFA139 is listed under Accessory Selection on your specific camera's datasheet before ordering.

04Why choose this

Built for the way you actually use the PFA139

Genuine Dahua fit

This is the factory DH-PFA139, designed to seat under Dahua turret and eyeball bodies so the camera base sits flush and the screw pattern lines up the first time.

Protects the connection

The sealed aluminium cavity keeps the network cable, RJ45 and any pigtail out of the weather and out of sight, which is where most water ingress and cable faults start on outdoor cameras.

Compact and tidy

At Ø108 mm it is the smallest box in the range, so it disappears behind a turret while still giving room to coil the cable for a neat, installer-grade finish.

Built for Australian conditions

Aluminium alloy resists corrosion in coastal and exposed sites far better than plastic alternatives, and shrugs off UV and heat.

05Where it fits

Right at home in these scenarios

Outdoor turret and eyeball installs

Mount a Dahua turret or eyeball under an eave or on a wall with the cable join sealed inside the box, away from rain and UV.

Rough or uneven surfaces

On brick, render or timber the box gives a flat, solid mounting face and hides any gap between the camera base and the wall.

Tidy cable entries

Bring the cable straight up through the wall into the base of the box for a clean finish with no exposed lead.

Retrofit tidy-ups

Cover an existing oversized cable hole behind a new turret when upgrading an older camera.

06Setup

Installation & setup

  1. What's in the box

    One DH-PFA139 junction box with an M20 water joint, four M4x10 screws, three ST4x25 screws, three plastic anchors and a wrench. The camera and network cable are not included.

  2. Installation requirements

    Fix the box to a flat wall or ceiling that can support several times the combined weight of the box and camera, using the supplied anchors in masonry. Bring the network cable in through the M20 entry and seal it with the water joint for outdoor use, then mount the camera onto the box. Add a bead of outdoor silicone around the base on exposed walls.

08Questions

Frequently asked about the PFA139

Q.01

Which cameras does the DH-PFA139 fit?
It is the compact junction box for Dahua turret and eyeball cameras. Because each camera has its own mounting pattern, Dahua lists the correct box under Accessory Selection on the camera's datasheet, so check that line for your exact model before ordering. If you are unsure, send us the camera model and we can confirm.
Q.02

Do I actually need a junction box for my turret camera?
Not always, but it helps. The DH-PFA139 gives a sealed cavity to coil and protect the cable and connector behind the camera, rather than leaving the join exposed. It is most worthwhile outdoors, on uneven surfaces, and where you want a clean cable entry with no lead running across the wall.
Q.03

Is the DH-PFA139 weatherproof outdoors?
It is an aluminium-alloy housing designed for weather-resistant outdoor mounting. Dahua does not publish a formal IP rating for this box, so for outdoor installs seal the cable entry at the M20 gland and run a bead of outdoor silicone where the base meets the wall, so wind-driven rain cannot track behind it. If you want a box with a stated IP66 rating, look at the DH-PFA130-E instead.
Q.04

What are the dimensions and load rating?
It measures Ø108.0 mm by 28.5 mm, weighs about 0.16 kg, and is rated to a 1.0 kg load. That is well above the weight of the lightweight turret and eyeball cameras it suits, so the wall fixings are the practical limit.
Q.05

What thread does the cable entry use?
The cable gland uses an M20 (G1/2 inch) thread, which is the common size across Dahua's smaller junction boxes. The box ships with the screws, anchors and a water joint needed to mount it and seal the entry.
Q.06

Is the camera included with the junction box?
No. This listing is for the junction box only. It is a mounting accessory you buy alongside the camera it suits.
Q.07

How is the DH-PFA139 different from the DH-PFA137?
They are the same style of turret and eyeball junction box in different sizes. The DH-PFA139 is the compact Ø108 mm box, while the DH-PFA137 is the larger Ø122 mm box with a bit more internal room. Match the box your camera's datasheet lists under Accessory Selection.
