§ 04Why choose this

Built for the way you actually use the DH-SDT4E425-8P-GB-APV1

8MP Panoramic + 4MP 25× PTZ

Fixed 8 MP sensor provides a wide overview while a 4 MP PTZ with 25× zoom tracks and zooms into targets. Two cameras in one unit.

TiOC Active Deterrence

Red and blue strobe plus siren on both panoramic and PTZ channels. Triggers on human or vehicle detection.

Auto-Linking Panoramic to PTZ

When the panoramic sensor detects a target, the PTZ automatically pans and zooms to follow it.

25× Zoom with 150 m IR

Much longer zoom and IR range than the 10× SDT3E410 model. Covers large car parks and compounds.

IP66 Weatherproof

Sealed dome handles rain, dust, and heat.

§ 05Where it fits

Right at home in these scenarios

Large Car Park or Depot

Panoramic view monitors the entire area. PTZ auto-zooms to track suspicious movement. 150 m IR covers the full lot at night.

Commercial Perimeter or Industrial Site

25× zoom reads plates at the gate. Siren and strobe deter trespassers. One unit replaces multiple cameras.

Sports Ground or Campus

Panoramic overview of the full grounds. PTZ zooms into specific incidents in real time.

Retail Centre or Mall Entrance

Wide view captures all foot traffic. PTZ zoom provides facial detail when needed.

§ 07Questions

Frequently asked about the DH-SDT4E425-8P-GB-APV1

Q.01

Does this take up two NVR channels?

Yes. The panoramic and PTZ streams are separate. Budget two channels on your NVR.

Q.02

How does the 25× model compare to the 10× SDT3E410?

The 25× version has much longer zoom and 150 m IR vs the 10×'s shorter range. Better for large open areas. The 10× is more compact and cheaper.

Q.03

Can I use just the panoramic without the PTZ?

Yes. Each sensor operates independently. You can disable auto-linking if preferred.

Q.04

Does it have a microphone and speaker?

Yes. Built-in mic and speaker for two-way talk and voice warnings.

Q.05

What NVR is recommended?

A Dahua NVR with at least 2 spare 8 MP channels and enough bandwidth. NVR5216-AI-ANZ or higher.
