Key Capabilities
4MP Starlight Imaging
The 1/2.8-inch CMOS sensor captures 2560 × 1440 video at up to 25/30fps. Starlight sensitivity, 120dB WDR and advanced noise reduction help retain useful detail across dim, backlit and rapidly changing outdoor scenes.
45× Long-Range Optical Zoom
The motorised 3.95–177.7mm lens changes the horizontal field of view from approximately 70.3° to 1.8°. Operators can move from a broad site overview to close inspection of a distant subject without relying on digital enlargement alone.
300m Infrared Illumination
Seven infrared illuminators provide a listed night range of up to 300 metres. Zoom-priority, manual and Smart IR controls adjust illumination behaviour as the camera moves between wide and telephoto views.
Deep-Learning Automatic Tracking
Automatic tracking controls the camera’s pan, tilt and zoom movements to follow a configured target. Tracking can be linked to supported intelligent events, helping operators maintain visual coverage of people or vehicles moving across large sites.
WizMind Target Classification
Tripwire and intrusion rules classify human and vehicle targets, while SMD Plus filters common non-target movement. Smart Capture and face detection add useful snapshots for monitoring and post-event investigation.
Professional Outdoor Integration
The camera combines an IP67 metal housing, integrated wiper, seven alarm inputs, two alarm outputs, RS-485 and external audio connections. This supports demanding projects requiring environmental protection and integration with other site systems.

Why Choose the DH-SD6AL445XA-HNR-IR
The DH-SD6AL445XA-HNR-IR is designed for sites where a fixed camera or basic PTZ cannot provide enough reach. Its 45× optical zoom allows operators to inspect distant activity while retaining a broad overview when required, and the 300-metre infrared system supports extensive night coverage. Automatic tracking, perimeter classification, Smart Capture, face detection and SMD Plus add more targeted monitoring than conventional motion detection. The integrated wiper, IP67 housing and wide operating-temperature range also suit exposed installations. Available through Security Wholesalers, this model should be specified from a complete site plan covering mounting height, zoomed evidence areas, tracking paths, bandwidth, storage, alarms, external audio and power. Fixed overview cameras may still be required while the PTZ follows another target.
Buyer Decision Tips

- Add fixed cameras if: Critical entrances or evidence zones must remain continuously recorded while the PTZ moves elsewhere.
- Choose another audio model if: A built-in microphone and speaker are required without external audio equipment.
- Confirm the mounting and power design if: The structure, bracket, Hi-PoE source or 36V DC supply has not been checked for this 6.5kg PTZ.
FAQs
- Does the DH-SD6AL445XA-HNR-IR record 4MP video at full frame rate?
The DH-SD6AL445XA-HNR-IR records up to 2560 × 1440 at 25fps in 50Hz systems or 30fps in 60Hz systems. It also provides two sub streams for lower-bandwidth viewing and recording. Actual performance depends on the selected bitrate, compression settings, network capacity, storage plan and the connected recorder’s decoding limits, particularly when several high-resolution streams are displayed at the same time.
- How useful is the 45× optical zoom for long-range surveillance?
The motorised 3.95–177.7mm lens changes the horizontal field of view from approximately 70.3° to 1.8°, allowing operators to move from a broad overview to close inspection of a distant target. The listed DORI identification distance is 355.4 metres, but this is a viewing-detail reference rather than an analytics guarantee. Lighting, atmosphere, vibration, mounting height and target movement can reduce practical results.
- Can this PTZ automatically track people or vehicles?
Yes. The camera supports deep-learning-based automatic tracking and can link tracking to supported intelligent events. Perimeter protection classifies human and vehicle targets, while Smart Capture can capture human, motor vehicle and non-motor vehicle images. Tracking performance depends on target size, contrast, speed, obstructions and commissioning. Fixed overview cameras may still be required where important areas must remain continuously recorded while the PTZ follows another target.
- How far does the infrared illumination reach?
The camera uses seven infrared illuminators with a listed maximum range of 300 metres. Zoom-priority, manual and Smart IR controls adjust the illumination behaviour as the lens moves between wide and telephoto positions. Actual usable distance varies with target reflectivity, weather, haze, nearby surfaces, mounting height and ambient light. The Starlight sensor also helps capture useful detail before maximum infrared output is required.
- Which intelligent analytics are built into the camera?
The DH-SD6AL445XA-HNR-IR supports tripwire and intrusion rules with human and vehicle classification, Smart Capture for human and vehicle images, face detection, SMD Plus and abandoned or missing object detection. Perimeter filtering helps reduce alarms caused by animals, moving leaves and bright lights. The camera also supports automatic tracking. Required analytics should be mapped before commissioning because not every function is intended for simultaneous use.
- Does the DH-SD6AL445XA-HNR-IR have built-in audio?
The supplied specification confirms one audio input and one audio output, but it does not confirm a built-in microphone or speaker. Compatible external audio equipment is therefore required when audio capture or playback is needed. The camera supports several audio codecs and can transmit audio through a compatible recorder or management platform. Audio use should comply with applicable privacy, workplace-surveillance and local recording requirements.
- What power, storage and alarm connections are available?
The camera supports 36V DC at 2.23A or Hi-PoE. Basic consumption is 20W and maximum consumption is 36W with infrared and PTZ movement active. It accepts a microSD card up to 256GB and supports FTP storage. Connections include seven alarm inputs, two alarm outputs, one audio input, one audio output and one RS-485 interface. The wall bracket, mount adapter and 36V power adapter are listed as included.
- What should I confirm before ordering this 4MP long-range PTZ camera?
Confirm the required overview and identification distances, mounting height, automatic-tracking rules, night coverage, NVR compatibility, bandwidth, storage retention, alarm wiring, external audio equipment and Hi-PoE or 36V DC power design. The camera weighs 6.5kg and requires suitable mounting hardware and structural support. Security Wholesalers can review the planned position and recorder to identify likely zoom, power, mounting or analytics limitations before installation.
