Dahua DH-SD5A445GB-HNR — 4MP 45x Optical Zoom PTZ Camera
The Dahua DH-SD5A445GB-HNR is a 4MP PTZ (pan-tilt-zoom) IP camera with 45x optical zoom, giving clear detail over long distances from a single mounting point. It combines AcuPick human and vehicle search with Auto Tracking 3.0 to follow activity automatically, and carries IP67 and IK10 ratings for outdoor, vandal-resistant installation.
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.

What you will need
- A PoE+ switch or injector, or a PoE NVR with a free PoE+ port, since this PTZ camera's motorised pan/tilt/zoom draws more power than standard PoE
- A wall or pole mounting bracket rated for PTZ housings, plus a stable structural fixing point given the camera's moving parts
- Network video management software or an NVR with ONVIF/Dahua PTZ control to drive pan, tilt, zoom and auto-tracking
Frequently asked questions
What does 45x optical zoom mean in practice?
The lens can magnify a scene up to 45 times without losing image quality, letting operators go from a wide overview to identifying a face, vehicle or object at distance — unlike digital zoom, which loses detail as it enlarges the image.
Does it need a PoE+ switch or NVR?
Yes. The motorised pan/tilt/zoom mechanism on the DH-SD5A445GB-HNR draws more power than a fixed camera, so it needs a PoE+ (802.3at) port on your switch, injector or NVR rather than standard PoE.
What is Auto Tracking 3.0?
It is Dahua's automatic tracking feature: once a moving person or vehicle is detected, the camera follows its trajectory across the field of view, reducing the need for an operator to manually drive the pan/tilt/zoom.
Is the DH-SD5A445GB-HNR suitable for outdoor use?
Yes. It is rated IP67 against dust and water ingress and IK10 against impact, making it suitable for exposed outdoor mounting positions.
