Dahua SD49425GB-HNR 4MP Starlight AI PTZ with 25x Zoom

Description

Razor-Sharp Image from a Long Distance: The Dahua AI PTZ Camera

Monitor your property, parking lot, or business premises down to the smallest detail with the Dahua SD49425GB-HNR . This advanced PTZ (pan-tilt-zoom) security camera combines a powerful 25x optical zoom with razor-sharp 4MP resolution, ensuring you never miss an incident. Thanks to its smart AI capabilities and superior Starlight technology for color night vision, this camera provides reliable 24/7 security.

Key Benefits of the Dahua SD49425GB-HNR:

Powerful 25x Optical Zoom: Effortlessly bring objects, license plates, or people closer without loss of quality. Perfect for covering great distances.
Exceptional Color Night Vision (Starlight): Even in minimal lighting, you'll get bright, detailed color images where standard cameras switch to grainy black and white.
Smart AI Detection (WizSense): Prevent false alarms. The camera distinguishes people and vehicles from other motion (such as animals or branches) for highly accurate alerts and recordings.
Rugged and Weatherproof (IP66): Designed for outdoor use in all weather conditions from heavy rain to freezing cold, and protected against surges.
Flexible Installation with PoE: Power and data via a single network cable (Power over Ethernet) for a simple and tidy installation.

The Power of WizSense Artificial Intelligence

This camera is more than just a lens. Built-in WizSense AI technology makes your surveillance proactive:

Perimeter Protection (IVS): Set up virtual tripwires or zones. You'll receive an immediate alert if a person or vehicle crosses this line.
SMD 4.0 (Smart Motion Detection): The camera filters out irrelevant movements and focuses purely on people and vehicles, dramatically speeding up the search for important events.
Face Detection: The camera can detect faces in the video stream and capture snapshots for later analysis.
