Dahua DH-SD4A425DB-HNY 4MP 25x Starlight IR WizSense Network PTZ Camera

See more. Miss less. The Dahua SD4A425DB-HNY PTZ camera delivers 4MP clarity across wide-open spaces - day or night.

Whether you're monitoring a large car park, a sprawling commercial property, or a multi-entry facility, a fixed camera often leaves blind spots. The Dahua DH-SD4A425DB-HNY solves that problem with a powerful 25× optical zoom and full pan-tilt-zoom control - so one camera can do the work of several, without compromising image quality.

Crystal-clear 4MP imaging

With 4-megapixel resolution, this PTZ camera captures sharp, detailed footage across its full zoom range. Whether you're zoomed out to survey an entire forecourt or zoomed in to read a number plate at distance, the image stays clear and usable.

25× optical zoom - cover more ground

The 25× optical zoom lets you monitor expansive areas from a single mounting point. Pan across a wide scene, then zoom in on a specific person or vehicle without losing detail - ideal for large retail sites, warehouses, transport hubs, and open outdoor areas.

100 m IR night vision for 24/7 monitoring

Security threats don't stop at sunset. The SD4A425DB-HNY features Starlight low-light technology combined with up to 100 m IR illumination, delivering clear footage in near-total darkness. Your site stays protected around the clock.

WizSense AI - smarter alerts, fewer false alarms

Powered by Dahua's WizSense deep learning engine, this camera can distinguish between humans and vehicles - filtering out irrelevant motion like animals or blowing debris. The result is more accurate alerts and less time wasted reviewing false triggers.

• Face detection - leverages facial data to enhance analytics accuracy and support identification workflows
• Auto Tracking 1.0 - automatically follows a moving person or vehicle across the scene, keeping the subject in frame without manual operator input

Discreet installation options

Need a low-profile setup? The SD4A425DB-HNY supports an optional smoked dome cover and in-ceiling mount, allowing the camera to blend into its environment - suitable for retail interiors, reception areas, and anywhere aesthetics matter alongside security.

Built for Australian conditions

With IP66 weatherproofing and TVS 6000V surge protection, this camera is rated to handle rain, dust, and the electrical transients common in Australian outdoor environments. Lightning strikes and power surges won't take your surveillance offline.

Is this camera right for your site?

The DH-SD4A425DB-HNY suits sites where:

• A single camera needs to cover a large or variable area
• You need to zoom in on detail at distance (e.g. entry points, loading docks, perimeter fences)
• 24/7 monitoring in low-light or no-light conditions is required
• AI-based classification is needed to reduce false alarm fatigue
• Discreet or flush-mount installation is preferred
