Dahua DH-IPC-HFW2531TP-ZS-S2 - 5MP Lite IR Varifocal Bullet PoE IP CCTV Camera

Dahua DH-IPC-HFW2531TP-ZS-S2 — 5MP Lite IR Night Vision Varifocal Bullet PoE IP CCTV Camera

The Dahua DH-IPC-HFW2531TP-ZS-S2 is a 5MP IP CCTV camera in a bullet housing, from Dahua's Lite series, with a 2.7-13.5mm motorised varifocal lens. Dahua's datasheet lists the model as DH-IPC-HFW2531T-ZS-S2, and the P in this model number is the PAL version. It combines built-in IR night vision up to 60m, Starlight low-light imaging, 120dB WDR and PoE power in an IP67 housing. 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. As a PoE security camera it can be powered over its network cable (802.3af), and as an ONVIF camera it supports Profile S, G and T.

Also listed as IPC-HFW2531TP-ZS-S2.

Dahua's datasheet code without the DH- prefix is IPC-HFW2531T-ZS-S2.

Common questions

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 100°) and narrow (horizontal 26°) without changing the lens.

How far does the IR night vision reach?

Dahua lists an IR illumination distance of 60 m from 4 built-in IR LEDs. Dahua's DORI figures are above: 64 m (wide) to 220 m (tele) to detect a person.

Does it need a separate power supply?

No. It runs on PoE (802.3af) or 12V DC, and uses under 9.9 W.

Does it support local storage?

Yes. It takes a Micro SD card up to 256 GB, and Dahua also lists NAS, FTP and SFTP storage.

What does Starlight mean?

Dahua uses Starlight for imaging in low light. Our guide to Dahua Starlight low-light cameras explains it.

Will it work with a recorder that is not Dahua?

It supports ONVIF Profile S, G and T, so it can be added to compatible third-party recorders.

Is it suitable outdoors?

It is IP67 rated and works from -30 °C to +60 °C.
