Dahua DH-PTZ1A225-HNR-GB — 2MP 25x Starlight IR Positioning System PTZ Camera
The DH-PTZ1A225-HNR-GB is part of Dahua's Positioning System range — a 2MP Starlight PTZ camera with 25x optical zoom built to work with deep-learning back-end analytics (Acupick, Auto Patrol) to automatically locate and zoom in on people and vehicles flagged by other cameras or an AI NVR, rather than relying on an operator driving the PTZ manually.
Who is it for?
Sites running an AI-enabled NVR or VMS where a fixed camera or panoramic view flags an event and this PTZ needs to automatically slew to and zoom in on the target — car parks, perimeters, retail floors — reducing the need for a human operator watching a joystick.

Frequently asked questions
What does 'Positioning System' mean?
It refers to Dahua's design for this PTZ to work alongside AI-enabled recorders or other cameras — automatically locating and zooming in on a flagged target rather than needing manual joystick control.
Does it need special software to auto-track?
The Acupick and Auto Patrol features work with compatible Dahua NVRs/VMS — the camera itself still works as a standard 25x PTZ on any ONVIF-compatible recorder.
Is it suitable for outdoor use?
Yes — IP67 rated with TVS 6000V protection against lightning, surge and voltage transients.
