See it in action

What the DH-SDT4E425-8P-GB-APV1 features actually look like

Representative illustrations of how each key feature performs in a real scene.

8MP Ultra HD

8MP (4K) resolution captures four times the detail of 1080p.
Even when a person or car is far down the driveway, you can zoom in and still recognise a face or read a number plate — detail that lower-resolution cameras lose.

30m IR Night Vision

Built-in infrared lets the camera see in complete darkness up to around 30m — enough for a typical driveway, front yard or entrance. People and vehicles stay clear in black-and-white, brighter the closer they are.

Dual-Light Night Vision

Combines infrared with a warm spotlight so it can light a scene in colour at night rather than relying on black-and-white alone — clearer, more useful footage when there's something to see.

Full Color Night Vision

Unlike plain black-and-white night vision, this camera can capture colour after dark — so you can pick out the actual colour of a car, a jacket or a bag, detail that grey infrared footage loses.

False Alarm Reduction

Filtering helps separate real activity from harmless movement like rain, leaves or pets, so you get fewer pointless notifications and the alerts that matter stand out.

Human/Vehicle Detection

Smart detection focuses on people and vehicles and can ignore things like swaying branches, rain or small animals — helping cut down false alerts and making the right moments easier to find.

Two-Way Audio

Talk and listen in real time through the app — tell a courier where to leave a parcel, or speak to someone at the gate, whether you're home or away.

Blue/Red Strobe

When activity is detected after dark, the camera can flash a bright red-and-blue strobe to warn intruders they've been seen — active deterrence, not just a recording for later.

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.

08Questions

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.
