Dahua DH-SD8A840-HNF-PA 8MP 40x Starlight AI Active-Deterrence PTZ Camera

The Dahua DH-SD8A840-HNF-PA is an 8MP (4K) AI PTZ camera with a 40x optical zoom lens, 360° endless pan and 90° tilt. Starlight low-light imaging and IR illumination up to 500m keep targets clear at night, while the PA active-deterrence warm white light and built-in two-way audio let operators warn off intruders in real time. AI auto-tracking, perimeter protection and PoE+ with ONVIF make it a powerful single-camera solution that pairs with a Dahua NVR.

40x Zoom in 4K

A long-range 40x optical zoom combined with 8MP 4K resolution reads faces and number plates at distance, while 360° endless pan and 90° tilt cover wide perimeters from a single mount.

Active Deterrence (PA)

The PA model adds a warm white deterrence light and two-way audio, so operators or automated rules can illuminate and verbally warn intruders the moment AI detects them.

Starlight & 500m IR

Starlight low-light technology captures detail in near-darkness, and IR illumination reaches up to 500m for clear night surveillance across large open sites.

AI Auto-Tracking

The camera automatically detects, locks on and follows people or vehicles with perimeter protection, cutting nuisance alarms and keeping targets centred without operator input.

What does the “PA” mean?
PA denotes the active-deterrence model: it adds a warm white light and two-way audio so operators can illuminate and verbally warn intruders, on top of the AI PTZ surveillance features.
How far can the 40x zoom see?
The 40x optical zoom with 4K resolution reads faces and plates at long range, and IR reaches up to 500m — ideal for large open sites, yards and perimeters.
What is auto-tracking?
The AI automatically detects a person or vehicle, then pans, tilts and zooms to keep the target centred and in focus without operator input.
What power does it need?
It runs on Hi-PoE/PoE+ (802.3at) or 24V AC. Use a PoE+ switch or injector rated for long-range PTZ cameras with IR and deterrence lighting.
