Dahua SD6E445MB-HNR-A-PV1 4MP 45x Smart Dual Illumination Active Deterrence Network PTZ Camera

Dahua 4MP 45x Smart Dual Illumination Active Deterrence Network PTZ Camera

The Dahua SD6E445MB-HNR-A-PV1 is a professional-grade PTZ security camera built for wide-area surveillance where a standard fixed camera is not enough. It combines 4MP video resolution, 45x optical zoom, long-range infrared, warm light illumination, active deterrence and intelligent target detection in one robust outdoor camera.

This model is designed for sites that need both broad coverage and the ability to zoom in on distant activity. The 45x optical zoom allows operators to view large areas and then focus on gates, driveways, loading docks, fence lines, car parks or distant movement without losing the flexibility of PTZ control. Dahua lists the camera with 4MP resolution, a 1/2.8″ CMOS sensor and a maximum image size of 2560 × 1440. :contentReference[oaicite:0]{index=0}

Smart Dual Illumination for Night Surveillance

The SD6E445MB-HNR-A-PV1 features Dahua Smart Dual Light technology, giving the camera both infrared and warm light capability. Dahua specifies up to 250m IR distance and up to 100m warm light distance, making it suitable for large outdoor areas where nighttime visibility is critical. :contentReference[oaicite:1]{index=1}

Infrared can be used for discreet black-and-white night monitoring, while warm light can assist with colour detail and visual deterrence when required. This makes the camera useful in locations where evidence quality and deterrent effect are both important.

Active Deterrence with Red/Blue Warning Lights and Audio

This PTZ includes red and blue warning lights and sound warning features for active deterrence. When configured with suitable rules and alarms, the camera can help warn intruders before an incident escalates. Dahua lists adjustable flashing duration, flashing frequency and built-in voice alarm options, with support for custom imported voice content. :contentReference[oaicite:2]{index=2}

For commercial and industrial sites, this can be useful for deterring after-hours trespassing, loitering, fence-line activity and unauthorised vehicle access.

AI Detection, AcuPick and Smart Tracking

The SD6E445MB-HNR-A-PV1 supports a range of intelligent detection features including IVS perimeter protection, SMD 4.0, WizTracking, AcuPick and video metadata. Dahua lists support for detecting motor vehicles, non-motor vehicles, faces and human bodies, as well as tripwire, intrusion, loitering, people gathering and parking detection functions. :contentReference[oaicite:3]{index=3}

AcuPick is designed to help quickly search for human and vehicle targets when used with compatible Dahua backend devices. This is especially helpful where operators need to locate a person or vehicle across recorded footage without manually reviewing long periods of video.

Built for Harsh Outdoor Environments

The camera is rated IP67 for weather protection and IK10 for vandal resistance, making it suitable for demanding outdoor installations. Dahua also lists TVS 6000V lightning protection, surge protection and voltage transient protection, along with an operating temperature range of -40°C to +70°C. :contentReference[oaicite:4]{index=4}

This makes the camera a strong option for outdoor commercial sites, exposed industrial locations, farms, yards, compounds and perimeter security applications.
