Dahua DH-SD4A425DB-HNY - 4MP 2K Starlight Infrared WizSense AI PTZ IP CCTV Camera

Dahua DH-SD4A425DB-HNY - 4MP 2K Starlight IR WizSense AI PTZ IP CCTV Camera

The Dahua DH-SD4A425DB-HNY is a 4MP IP PTZ camera from Dahua's WizSense SD4 range. A 1/2.8 inch STARVIS CMOS records 2560 x 1440 at up to 25/30fps through a 5mm to 125mm lens with 25x optical zoom, and the horizontal field of view runs from 51.9 degrees down to 3.0 degrees.

Six IR illuminators reach up to 100m, and Starlight imaging gives colour down to 0.005 lux. The camera pans 360 degrees endlessly at up to 240 degrees per second and tilts from -5 to +90 degrees, with 300 presets, 8 tours, 5 patterns and 5 scans. Auto Tracking 1.0 follows a moving target, while perimeter protection, SMD 3.0 and face detection classify humans and vehicles.

It records to a Micro SD card of up to 512GB, or to an NVR over ONVIF Profile S, G, T and M. Power is 12V DC 2A from the included adapter or PoE+ (802.3at), with a maximum of 21.5W. The housing is IP66 rated with TVS 6000V protection for -40 to +65 degrees C.

Also listed as SD4A425DB-HNY.

Common questions

What does WizSense mean on the SD4A425DB-HNY?

Dahua lists this camera in its WizSense series, a range of AI products that use an independent AI chip and deep-learning algorithms and focus on humans and vehicles. Our WizSense guide explains the range.

Does it have Starlight low light imaging?

Yes. Dahua lists Starlight technology, with 0.005 lux minimum illumination in colour and 0.0005 lux in black and white, plus IR illumination up to 100 m. Our Starlight guide explains what Starlight means.

How does the auto tracking work?

Auto-tracking 1.0 controls the pan, tilt and zoom actions of the camera to follow an object in motion and keep it in the scene. It can be triggered manually or by defined rules, after which the camera can zoom in and track the target automatically.

Does it come with a power supply?

Dahua lists a DC 12 V/2 A power adapter as an included accessory. The camera also runs from PoE+ (802.3at).

Is it suitable for outdoor use?

Yes. It has an IP66 rating with TVS 6000 V lightning, surge and voltage transient protection, and Dahua lists an operating range of -40°C to +65°C.

Which mounts does Dahua list for it?

Dahua lists a mount adapter (PFA101) and wall, ceiling, corner, parapet and pole mount brackets as accessories. The ones we supply are under Works with above.

Does the DH-SD4A425DB-HNY have a memory card slot?

Yes. It takes a Micro SD card of up to 512GB, and it can also store footage to NAS or send it by FTP or SFTP.

How much optical zoom does it have?

25x optical zoom from a 5mm to 125mm lens (F1.6 to F3.6), plus 16x digital zoom. The horizontal field of view narrows from 51.9 degrees to 3.0 degrees.

Will it work with a non-Dahua NVR?

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