Dahua DH-SD4D425MB-HNR — 4MP 25x Optical Zoom PTZ Camera
The Dahua DH-SD4D425MB-HNR is a 4MP network PTZ camera with 25x optical zoom (5-125mm focal length) and a further 16x digital zoom, giving operators close-up detail across a wide area from a single mounting point. Smart Dual Light combines IR and white-light illumination for up to 100m night-time coverage, while WizTracking keeps a detected target in view and automatically returns the camera to its preset patrol route once the event ends. AcuPick uses deep-learning search to quickly locate a specific person or vehicle across live and recorded footage.
Who is it for?
PTZ cameras cover a wide area from one mounting point, giving operators (or auto-tracking) pan/tilt/zoom control to follow activity or zoom into detail — useful for open sites, car parks, perimeters and any area too large for a single fixed camera to cover in detail.
