Dahua DH-SD6AL445GB-HNV-IR - 4MP 2K 45x Zoom AI Starlight Infrared PTZ IP CCTV Camera

Dahua DH-SD6AL445GB-HNV-IR - 4MP 2K 45x Zoom Starlight IR Outdoor PTZ IP CCTV Camera

The DH-SD6AL445GB-HNV-IR is a 4MP (2560 x 1440) PTZ camera with 45x optical zoom, for watching large outdoor areas from one mounting point: perimeter fences, yards, car parks and estate roads. The 3.95-177.7 mm lens goes from a 63.2 degree wide view down to 1.8 degrees, so an operator can sweep a site and then zoom in on a vehicle or person far away.

Seven IR illuminators reach up to 300 m, and the Starlight sensor holds colour down to 0.005 lux. Auto Tracking 3.0 follows a moving target, and the built-in perimeter protection (tripwire, intrusion, crossing fence, loitering) and SMD 4.0 are aimed at people and vehicles to cut false alarms from foliage and weather.

It is built for exposed sites: IP67, TVS 6000 V lightning and surge protection, a wiper, and an operating range of -40 C to +70 C. Power is Hi-PoE or 36 VDC, with a maximum draw of 27 W with the IR and PTZ running.

Also listed as SD6AL445GB-HNV-IR.

Works with

Dahua's ordering information lists a PFA111 mount adapter, a PFB303W wall mount bracket and a DC36V/2.23A power adapter with the camera, and the PFB300C ceiling mount, PFA150 pole mount and PFA151 corner mount (used with the PFB303W) as optional accessories. Stocked by Zenith: Dahua PFA111 mount adapter, Dahua PFB303W wall mount bracket, Dahua PFB300C ceiling mount and Dahua PFA151 corner mount bracket.

Shorter-range Dahua PTZ options: DH-SD49425GB-HNR (4MP, 25x zoom, 100m IR) and DH-SD49225DB-HNY (2MP, 25x zoom, 100m IR).

• Dahua DHI-NVR5232-EI2 32 Channel NVR: 32 channels for IP cameras up to 32MP, so the 4MP stream sits well inside its limits.

These are general compatibility suggestions (same brand, ONVIF IP, matching power and channel specifications), not pairings we have tested.

Common questions

How far can the Dahua DH-SD6AL445GB-HNV-IR see at night?

Its 7 IR illuminators give an illumination distance of up to 300 m (984 ft). Minimum illumination is 0.005 lux in colour and 0.0005 lux in black and white at F1.6, and 0 lux with the IR light on. Our Dahua Starlight guide explains what Starlight low light technology means.

What resolution does it record?

The main stream is 4MP at up to 2560 x 1440, often called 2K. The main stream also offers 3M, 1080p, 1.3M and 720p at 1-25/30 fps, and the camera supports 3 streams.

How is it powered?

By Hi-PoE or 36 VDC (2.23 A, ±25%). Power consumption is 13 W basic and 27 W maximum with the illuminator and PTZ running. Dahua's ordering information lists a DC36V/2.23A power adapter as included.

Is it suitable for outdoor use?

Yes. It is rated IP67, works from -40 °C to +70 °C at up to 95% humidity, has a wiper and carries TVS 6000 V lightning, surge and voltage transient protection.

What can the built-in analytics do?

It offers auto tracking 3.0 and SMD 4.0, perimeter protection (tripwire, intrusion, crossing fence, loitering and more), face detection and video metadata that detects motor vehicles, non-motor vehicles, faces and human bodies.

Can it record to a card?

Yes. It takes a Micro SD card up to 512 GB and can also send to FTP/SFTP or NAS storage.

Does it record audio?

It has a 1-channel audio input and a 1-channel audio output on bare wires, so it needs an external microphone to record sound. Check local privacy rules before recording audio.
