Dahua DH-SDT6E425-8P-MB-A-PV1-0280 - 8MP 4K + 4MP 25x Dual Lens AI PTZ CCTV Camera

Dahua DH-SDT6E425-8P-MB-A-PV1-0280 - 8MP 4K + 4MP 25x Dual Lens AI PTZ Camera

The Dahua DH-SDT6E425-8P-MB-A-PV1-0280 is an X-Spans dual-channel PTZ camera that pairs a fixed 8MP overview channel with a 4MP 25x zoom detail channel. The overview channel uses a 1/2.7 inch CMOS and a 2.8mm lens to record 4096 x 1860 across a 180 degree horizontal view, and the detail channel uses a 1/2.8 inch CMOS behind a 5mm to 125mm lens (51.9 to 3.0 degrees).

On the detail channel, IR reaches up to 250m and warm light up to 100m, with Smart Dual Light switching to full colour when a target appears. The PTZ pans 360 degrees endlessly and tilts from -20 to +90 degrees, at preset speeds of up to 300 degrees per second pan and 200 degrees per second tilt. Smart tracking links the two channels so the detail camera follows targets the overview camera picks up, and red-blue warning lights, sound alarms and two-way talk give active deterrence.

It records to a Micro SD card of up to 512GB, to NAS, or to an NVR over ONVIF Profile S, G and T on a gigabit RJ-45 port. Power is 36V DC 2.23A or PoE++ (802.3bt), with a maximum of 40W. The housing is IP67 and IK10 rated for -40 to +70 degrees C.

Also listed as SDT6E425-8P-MB-A-PV1-0280.

Dahua's base model code is SDT6E425-8P-MB-A-PV1. A smaller X-Spans option is the DH-SDT4E425-4F-GB-A-PV1-0280-S2 (4MP+4MP, 25x zoom).

Common questions

Is it one camera or two?

It is one X-Spans unit with two channels: an 8MP overview channel and a 4MP detail channel with 25x optical zoom. Dahua says the overview camera links with the detail camera to track targets.

Can it check workers are wearing hard hats?

Dahua lists construction monitoring on the detail channel. It detects 6 helmet colours (red, orange, yellow, blue, white and black) and raises an alarm when a person is not wearing a helmet or the colour does not match. It also supports work uniform compliance detection.

What is Smart Dual Light?

The IR illuminator is usually on at night. When a target appears, the white light switches on and the camera records full-colour video of key events, then returns to IR when the target leaves. See our Smart Dual Light guide.

What active deterrence does it have?

A red and blue light warning with a flash duration of 5 s to 30 s, and a sound warning with 11 sound alarms plus up to 10 custom sounds, with built-in dual mics and a speaker for two-way talk. See our active deterrence guide.

Is it a CCTV camera?

Yes. It is a network PTZ camera for CCTV, working on an IP network with ONVIF (Profile S, G and T) and RJ-45 100/1,000 Base-T.

How is it powered?

36 VDC/2.23 A ±25% or PoE++ (802.3bt). Dahua lists a DC36V/2.23A power adapter as included. Power consumption is 19 W basic and up to 40 W maximum.

Is it weatherproof and impact rated?

Yes. It is a waterproof camera for outdoor camera use: Dahua rates it IP67 and IK10, with TVS 6000 V lightning, surge and voltage transient protection, and an operating range of -40 °C to +70 °C.

How does it compare with the 32x version?

The DH-SDT6E432-8P-MB-A-PV1-0280 has the same 8MP overview channel, with a 32x detail channel (4.8 mm to 154 mm) in place of the 25x (5 mm to 125 mm).

Where does it store recordings?

On a Micro SD card of up to 512GB in the camera, on NAS, or by FTP or SFTP. It can also be recorded by an NVR.

Will it work with a non-Dahua NVR?

Dahua lists ONVIF Profile S, G and T, so it can be added to recorders that support ONVIF.

Can I view it on a phone?

Yes. Dahua lists iOS and Android mobile clients for this camera.
