What the DH-SD4A425DB-HNY features actually look like
Representative illustrations of how each key feature performs in a real scene.
4MP Ultra HD
4MP captures roughly twice the detail of standard 1080p.
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.

04Why choose this
Built for the way you actually use the DH-SD4A425DB-HNY
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.

08Questions
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.
Buying from Smarket
Is your Hikvision, Dahua, HiLook and TP-Link VIGI stock genuine Australian stock?
Yes, 100%. Every Hikvision, Dahua, HiLook and TP-Link VIGI product we sell is a genuine Australian-market model sourced through Australian supply chains — never grey imports. That means factory-sealed units, Australian-region firmware that works with the official apps out of the box, and a full 3-year local warranty.
How long does delivery take?
