§ 01Overview

What the PFA138 is

The Dahua DH-AC-PFA138 is a large round water-proof junction box for bigger Dahua dome, turret and eyeball cameras. Its standout feature is a factory-fitted safety rope hook: you can clip the camera's safety lanyard to the box so the camera is held securely while you make the connections and bolt it down, which is a real help when fitting a heavier camera at height. As with any junction box, it also hides and seals the cable join behind the camera for a neat, protected finish.

It is made from aluminium with a white finish to match Dahua camera bodies, measures Φ161.0 mm x 37.0 mm, uses a G3/4" thread and is rated to carry up to 3.0 kg, suiting larger camera bodies. As a mounting accessory its datasheet describes it as water-proof but does not state a numeric IP code, so we describe it as weatherproof rather than quoting a specific rating. Keep the camera within the 3.0 kg load rating.

The PFA138 suits larger Dahua dome, turret and eyeball cameras where a bigger base and the safety hook are useful. Because the exact fit depends on the camera's base and screw pattern, always check your camera's compatible-mount list before ordering. The kit includes the box and mounting hardware, and it operates from -40 to +60 degrees C, covering the full range of Australian conditions.

Use the safety hook to hold the camera while making connections up a ladder or on a pole.

Tidy sealed cabling

Hide the cable join behind the camera with a sealed entry for a clean finish.

Exposed outdoor positions

Protect the connector on a wall or eave from rain and dust on a larger camera.

§ 06Setup

Installation & setup

01

Check camera fit

Confirm your dome, turret or eyeball model lists the PFA138 in its compatible-mount selection before fitting.

02

Mark and drill

Position the box where the camera will sit, mark the holes, then drill and insert suitable fixings.

03

§ 07Questions

Frequently asked about the PFA138

Q.01

What is the DH-AC-PFA138 used for?
It is a large round junction box for bigger Dahua dome, turret and eyeball cameras. It hides and seals the cable join behind the camera and adds a safety rope hook to hold the camera during install.
Q.02

What is the safety rope hook for?
It is a factory lanyard point. You clip the camera's safety rope to the hook so the camera is held securely while you make the connections and bolt it down, which is helpful when fitting a heavier camera at height.
Q.03

Which cameras does the PFA138 fit?
It suits larger Dahua dome, turret and eyeball cameras where a bigger base and the safety hook are useful. Fit depends on the camera base, so check your camera's compatible-mount list before ordering.
Q.04

How is it different from the PFA136?
The PFA138 is larger at Φ161 mm with a 3.0 kg load rating, a G3/4" thread and a safety rope hook. The PFA136 is a smaller Φ110 mm box rated to 1.0 kg for more compact dome and turret cameras.
Q.05

Is the PFA138 weatherproof?
Its datasheet describes it as water-proof but does not state a numeric IP code, so we describe it as weatherproof for typical outdoor positions.
Q.06

How much weight can it hold?
It has a load bearing rating of 3.0 kg, which suits larger camera bodies. Keep the camera's weight within that figure.
Q.07

What thread does it use?
It uses a G3/4" thread, the larger thread Dahua uses on its bigger junction boxes and brackets, rather than the M20 (G1/2") used on the small boxes.
Q.08

Do I need a junction box for my camera?
It is optional but useful for larger cameras, where it hides the cabling, gives a sealed cable entry and adds a safety lanyard point for installing at height.
