§ 01Overview

What the PFA121 is

The Dahua DH-PFA121 is a water-proof junction box designed to mount a Dahua bullet camera and conceal its cabling at the same time. Rather than leaving the network lead and connector exposed at the wall, the camera sits on the box and the cable join is hidden and sealed inside, which both tidies the install and protects the weakest part of any outdoor camera run - the plug and pigtail - from weather.

It is made from aluminium with a white finish to suit Dahua's bullet camera bodies, measures 134.0 x 133.5 x 56.0 mm, uses a G3/4" pipe thread and is rated to carry up to 3.0 kg, comfortably more than a typical bullet camera. Importantly, this box carries an IP66 rating, so it is genuinely sealed against heavy dust and powerful water jets for exposed outdoor positions. Cable entry is available from both the bottom and the side, which makes it easy to route the lead neatly whether the cable comes up through the wall or along the surface.

The DH-PFA121 fits Dahua bullet models including the HFW2 and HFW4/5/8 series (for example HFW2221/2231/2401E, IPC-HFW4231/4431/4830E-S, HFW3231E-Z and IPC-HFW5231/5431/5830 families). Because the exact fit depends on the camera's base, always check your camera's compatible-mount list before ordering. The kit includes the box, mounting screws, anchors and a waterproof joint, ready to install. It operates from -40 to +60 degrees C, suiting the full range of Australian conditions.

§ 04Why choose this

Built for the way you actually use the PFA121

Genuinely IP66 sealed

Bottom and side entry hides the RJ45 join inside the box for a clean, professional finish.

Strong and matched

Aluminium build rated to 3 kg, with a white finish that suits Dahua bullet camera bodies.

Ready to fit

Supplied with screws, anchors, a waterproof joint and wrench for a standard wall or pole install.

§ 05Where it fits

Right at home in these scenarios

Exposed wall mounting

Mount a bullet camera on an outside wall with the cable join sealed against rain and dust.

Pole and eave installs

Fix a camera to a pole or under an eave with cabling routed neatly out of sight.

Protecting the connector

Shield the RJ45 plug and pigtail - the weakest point of an outdoor run - inside a sealed box.

Tidy professional finish

Give a home or business install the clean look of a hidden cable join.

§ 06Setup

Installation & setup

01

Check camera fit

Confirm your Dahua bullet model is listed for the PFA121 in its compatible-mount list before fitting.

02

Mark and drill

03

Route the cable

Bring the network lead in through the bottom or side entry and fit the waterproof joint over it.

04

Mount and seal

Fix the box, connect and tuck the cable join inside, then attach the camera and check the seal is closed.

§ 07Questions

Frequently asked about the PFA121

Q.01

What is the DH-PFA121 used for?
It is a water-proof junction box that mounts a Dahua bullet camera and hides the cabling behind it. The cable join sits sealed inside the box, which tidies the install and protects the connector from weather.
Q.02

Which cameras does the PFA121 fit?
It is designed for Dahua bullet cameras, including HFW2 and HFW4/5/8 families such as HFW2221/2231/2401E, IPC-HFW4231/4431/4830E-S and HFW3231E-Z. Fit depends on the camera base, so check your camera's compatible-mount list before ordering.
Q.03

Is the PFA121 weatherproof for outdoor use?
Yes. It is rated IP66, so it is sealed against heavy dust and strong water jets and is suitable for fully exposed outdoor mounting on a wall or pole.
Q.04

How much weight can it hold?
It has a load bearing rating of 3.0 kg, which is comfortably more than a typical bullet camera weighs, so the camera is held securely.
Q.05

Where do the cables go in?
Cable entry is available from both the bottom and the side of the box, so you can route the lead neatly whether it comes up through the wall or runs along the surface.
Q.06

What is in the box?
It comes with the junction box, mounting screws, plastic anchors, a waterproof joint and a wrench, so you have the fixings needed for a standard wall or pole install.
Q.07

Do I really need a junction box?
It is optional but recommended for outdoor bullet cameras. It protects the cable join from weather and gives a neat, secure finish instead of leaving the connector exposed at the wall.
Q.08

What is the difference between this and a wall mount bracket?
A junction box like the PFA121 mounts the camera flat to a surface and hides the cabling. A wall mount bracket such as the PFB204W arms the camera out from a wall for a different angle or to clear an eave.
