Dahua DH-IPC-HFW3541TP-ZAS-27135-S2 - 5MP 3K WizSense AI IR Varifocal Bullet PoE IP CCTV Camera

Dahua DH-IPC-HFW3541TP-ZAS-27135-S2 — 5MP 3K WizSense AI IR Night Vision Varifocal Bullet PoE IP CCTV Camera

The Dahua DH-IPC-HFW3541TP-ZAS-27135-S2 is a 5MP 3K WizSense AI IP CCTV camera in a bullet housing with a 2.7-13.5mm motorised varifocal lens (the 27135 in the model number). Dahua lists the model as DH-IPC-HFW3541T-ZAS-S2, and the P in this model number is the PAL version. It is part of Dahua's WizSense 3 Series, with AI Coding to save bandwidth and storage, 60m IR night vision, a built-in microphone and PoE power. The camera listed as DH-IPC-HFW3541TP-ZAS-27135 is a different, Lite AI version. The IP67 housing is rated for outdoor use from -30 °C to +60 °C, and the 4 built-in IR LEDs reach up to 60 m for night vision. WizSense AI also makes it a smart camera that classifies humans and vehicles, and as a PoE security camera it can be powered over its network cable (802.3af).

Also listed as IPC-HFW3541TP-ZAS-27135-S2 (Dahua listing name: IPC-HFW3541T-ZAS-S2).

Common questions

Is it a 3K camera?

The sensor outputs up to 2960 × 1668 at 20 fps (5MP), and also 2880 × 1620 at 20 fps, which is the 3K class. It streams 2688 × 1520 at 25/30 fps.

What does WizSense mean?

WizSense is Dahua's AI range, using deep learning to focus on humans and vehicles. See our guide to Dahua WizSense cameras.

Can the view be adjusted after installation?

Dahua lists a motorized vari-focal lens from 2.7 mm to 13.5 mm, so the view can be set between wide (horizontal 99°) and narrow (horizontal 28°) without changing the lens.

Does it have a built-in microphone?

Yes. Dahua lists a built-in microphone for the -ZAS version, plus one RCA audio input and one RCA audio output, and one alarm input and one alarm output.

How far can it see?

Dahua's DORI figures are above: from 64.0 m (wide) to 210.0 m (tele) to detect a person, and 6.4 m to 21.0 m to identify one. The IR reaches up to 60 m.

Does it need a separate power supply?

No. It runs on PoE (802.3af) or 12 VDC. Dahua gives 3.4 W basic and 8.5 W maximum on PoE.
