Dahua DH-SD4A425DB-HNY — 4 MP 25× Optical Zoom Compact Pro AI Network PTZ Camera WizSense (4-Series Starlight)

The Dahua DH-SD4A425DB-HNY is the 4-Series compact WizSense PTZ — a project-grade 4 MP Starlight PTZ in a smaller, lighter form factor than the 5-Series flagship. Built around a 1/2.8" CMOS Starlight sensor capturing 2688 × 1520 at 25/30 fps. The 25× optical zoom lens with auto-focus delivers a wide 59° field down to a tight 3° pull at full zoom — identification-grade reach at 80–100 m. Built-in IR reaches up to 100 m; WDR is 120 dB; the metal housing is IP66 sealed. WizSense deep-learning Pro AI runs perimeter protection, Auto Tracking 3.0 and SMD 4.0. The smaller chassis suits installs where the flagship 5-Series is too heavy or where mounting clearance is limited — awnings, smaller poles, mid-rise commercial corners and project carparks. Backed by a 3-year Australian warranty through CCTV Guru. SKU SD4A425 series.

Why Choose the Dahua SD4A425DB-HNY Compact Pro AI PTZ

25× Optical Zoom in a Compact Body

True 25× optical zoom in a chassis that's smaller, lighter and cheaper than the 5-Series flagship. Ideal where the larger SD5A won't physically fit or the bracket budget is tight.

100 m Long-Range IR

Built-in IR array reaches up to 100 m at full zoom.

Auto Tracking 3.0

WizSense automatic person and vehicle tracking with pan/tilt/zoom follow.

Perimeter Protection (IVS)

Tripwire, intrusion, fast-moving, loitering, parking and people gathering with human/vehicle classification.

1/2.8" Starlight Sensor

Starlight sensor maintains usable colour at low ambient before IR engages.

Built-in Mic + Audio I/O

Built-in microphone, 1/1 audio I/O for two-way talk integration.

Important Install Note

Compact PTZs trade pure reach for mounting flexibility. For maximum 32× zoom and 150 m IR, use the 5-Series SD5A432GB-HNR. This 4-Series compact is the right choice for sites where the 5-Series is too big or budget too tight. Powered by High-PoE (802.3bt) or 24 VAC.

      Amazing zoom and clarity

      Camera is great.

      Zoom and focus is amazing

      When installed with a ceiling flush mount it is neat and not overly noticeable.
