§ 04Why choose this

Built for the way you actually use the DH-SD4A425DB-HNY

25× Zoom in a Mini PTZ Body

5–125 mm motorised lens in a compact dome. Full PTZ power without the bulk of a speed dome.

Starlight Sensor

1/2.8" CMOS with good low-light colour performance. Clear footage in dim conditions before IR activates.

100 m IR Range

Covers large areas in complete darkness. Smart IR adjusts intensity.

SMD 4.0 and Face Detection

Deep learning AI for accurate human and vehicle classification. Face detection for access-focused applications.

IP66 Weatherproof

Sealed against dust and rain. Operates from -40°C to 70°C.

§ 05Where it fits

Right at home in these scenarios

Car Park or Compound

25× zoom reads plates at distance. 100 m IR covers the lot. Compact dome is less obtrusive than full-size PTZ.

Warehouse or Logistics Yard

Pan and tilt to follow trucks and workers. SMD 4.0 reduces false alarms.

Residential Estate or Strata

Compact design suits residential environments. Patrol presets cover entry gates and common areas.

Retail or Office Perimeter

Face detection logs visitors. Zoom in to check specific areas remotely.

§ 07Questions

Frequently asked about the DH-SD4A425DB-HNY

Q.01

How is this different from the SD49425GB-HNR?
Same core specs (4 MP, 25× zoom, 100 m IR). The SD4A425DB is the newer DB-series housing with updated firmware. Check availability for your region.
Q.02

Does it have active deterrence?
No siren or strobe. For TiOC deterrence, look at the SD3E405DB or SD6C3425 models.
Q.03

Does it need PoE+?
Yes. Standard PoE is not enough for the PTZ motor.
Q.04

Does it have a microphone?
Audio input and output ports, but no built-in mic. Connect an external microphone if needed.
Q.05

What SD card does it support?
Up to 256 GB microSD.
