Dahua DH-IPC-HFW7442HP-Z-2712F-DC12AC24V-S2 - 4MP AI Motorised Varifocal Bullet Network Camera

Dahua DH-IPC-HFW7442HP-Z-2712F-DC12AC24V-S2 — 4MP Bullet IP Camera

The Dahua DH-IPC-HFW7442HP-Z-2712F-DC12AC24V-S2 is a 4MP bullet-style IP camera fitted with a motorised 2.7mm-12mm varifocal lens, giving you an adjustable field of view without swapping the lens on site. Onboard AI analytics cover face and body detection (with PPE detection), face recognition, video metadata, people counting and perimeter protection, plus automatic privacy masking that blurs faces and bodies in the live and recorded image.

Who is it for?

IP cameras carry video and PoE power over one Cat5e/Cat6 cable to a PoE NVR — ideal when cabling from scratch or wanting resolutions/analytics beyond coax. At 4MP, this bullet camera suits entrances, yards, loading bays and perimeter lines where you need a clear, directional view along with people counting or perimeter alerts built straight into the camera. The bullet housing suits sites where a visible, weather-resistant camera is preferred over a discreet dome, and the motorised varifocal lens lets an installer fine-tune the angle of view remotely rather than climbing back up a ladder.

Key specification

What you will need

• A PoE NVR that supports at least 4MP recording — see our NVRs
• Cat5e or Cat6 cabling run from the camera to the NVR or switch location
• For long runs or where you're branching out to several cameras, a PoE switch between the camera and the NVR
• Clear GDPR signage where the camera covers a public or shared area, even with privacy masking enabled

Frequently asked questions

Will this camera work with a non-Dahua NVR?

Yes. It supports ONVIF, so it will connect to most third-party NVRs, though some Dahua-specific AI features are only fully exposed when paired with a Dahua NVR.

Does it need a separate power supply?

No, if you're powering it from a PoE NVR or PoE switch. It also accepts DC12V or AC24V power directly if you're not using PoE.

How much storage will I need?

At 4MP, storage depends on frame rate and camera count; continuous 4MP recording typically needs several hundred GB per camera per week, so size your NVR's hard drive accordingly — get in touch and we can help.

Can I adjust the field of view after installation?

Yes, the 2.7mm-12mm lens is motorised, so zoom and focus can be adjusted remotely from the NVR or Dahua software without physically refocusing the lens.
