Product SKU: DH-SD5A425GB-HNR
Product Overview
The Dahua DH-SD5A425GB-HNR is a 4MP WizSense network PTZ camera designed for long-range surveillance across car parks, warehouses, industrial facilities, campuses, gates and property perimeters. Its motorised 5–125mm lens provides 25× optical zoom, allowing operators to move from a broad site overview to close inspection of distant people or vehicles. Four infrared illuminators provide a listed night range of up to 150 metres, supported by Starlight low-light imaging, 120dB WDR, electronic image stabilisation and electronic defog. Auto Tracking 3.0, human and vehicle perimeter classification, SMD 4.0, face detection, video metadata, people counting, Auto Patrol and AcuPick support intelligent monitoring and investigation. The IP67 and IK10 housing accepts PoE+ or 24V DC power and includes a wall bracket and power adapter. Fixed overview cameras may still be required while the PTZ follows another target.
Key Capabilities
4MP Starlight Imaging
The 1/2.8-inch CMOS sensor records at up to 2560 × 1440 and 25/30fps. Starlight sensitivity, 120dB WDR and noise reduction help retain usable detail across dim, backlit and rapidly changing outdoor scenes.
25× Long-Range Optical Zoom
The 5–125mm motorised lens changes the horizontal field of view from 51.9° to 3.0°. This allows operators to inspect distant activity without relying only on digital enlargement, while PFA technology helps maintain focus as the lens zooms.
150m Infrared Illumination
Four infrared illuminators provide a listed night range of up to 150 metres. Zoom-priority, automatic and manual controls adjust illumination behaviour as the camera moves between wide and telephoto views.
Auto Tracking 3.0
Automatic tracking controls the pan, tilt and zoom movements to follow a configured target. Supported IVS rules can trigger tracking, helping operators retain visual coverage of people or vehicles moving through large outdoor areas.
WizSense Target Classification
Perimeter analytics classify human and vehicle targets, while SMD 4.0 helps filter common non-target movement. Auto Patrol, face detection, video metadata, people counting and AcuPick add useful tools for monitoring and post-event investigation.
Professional Outdoor Integration
The camera combines IP67 and IK10 protection with alarm inputs, an alarm output, external audio connections and microSD storage. PoE+ or 24V DC power and several mounting options support professional site integration.
Best For
- Industrial Facilities: Monitors equipment yards, restricted zones, production areas and long building perimeters.
- Car Parks and Transport Sites: Provides long-range zoom and automatic tracking across vehicle routes and open areas.
- Commercial Campuses: Supports central monitoring of entrances, buildings, pathways and shared outdoor spaces.
- Warehouses and Logistics Sites: Tracks people and vehicles around loading docks, yards and access roads.
- Large Rural Properties: Inspects distant gates, sheds, roads, equipment areas and property boundaries.
Why Choose the DH-SD5A425GB-HNR
The DH-SD5A425GB-HNR is better suited to large sites than a basic fixed camera or short-range PTZ. Its 25× optical zoom allows operators to inspect distant activity while retaining a broader overview when required, and the 150-metre infrared system supports extensive night coverage. Auto Tracking 3.0, human and vehicle classification, SMD 4.0 and Auto Patrol provide more targeted monitoring than conventional motion detection alone. Available through Security Wholesalers, this model should be specified from a complete site plan covering mounting height, tracking paths, zoomed evidence areas, bandwidth, storage, alarms, external audio and power. It is a substantial 4.7kg PTZ, and fixed cameras may still be needed to maintain continuous views of critical areas while it tracks another subject.
Buyer Decision Tips
Distance and Tracking Tip: DORI figures describe theoretical viewing detail and do not represent guaranteed analytics or identification performance. Weather, haze, vibration, mounting height, target movement and scene contrast can reduce practical results.
Audio, Power and Mounting Tip: The camera provides line-level audio input and output but no confirmed built-in microphone or speaker. Confirm PoE+ or 24V DC power and use suitable structural support for the 4.7kg camera.

Choosing the Right Model
- Choose this model if: The site requires 4MP resolution, 25× optical zoom, Auto Tracking 3.0 and 150m infrared.
- Choose a higher-zoom PTZ if: The critical evidence area is beyond the practical reach of the 125mm telephoto position.
- Add fixed cameras if: Important 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 mounting and power if: The structure, bracket, PoE+ source or 24V DC supply has not been checked for this 4.7kg PTZ.
FAQs
- What is the DH-SD5A425GB-HNR designed for?
The DH-SD5A425GB-HNR is a 4MP outdoor network PTZ camera for long-range surveillance across car parks, warehouses, industrial sites, campuses, gates and property perimeters. Its 25× optical zoom, 150m infrared illumination and automatic tracking help operators follow and inspect distant activity. It should be used with a compatible recorder or management platform and a mounting structure suitable for its 4.7kg weight.
- How useful is the 25× optical zoom?
The 5–125mm motorised lens provides 25× optical zoom, changing the horizontal field of view from 51.9° to 3.0°. This allows an operator to move from a broad overview to close inspection of a distant person or vehicle without relying only on digital enlargement. Practical detail still depends on lighting, atmosphere, vibration, mounting height, target movement and correct focus.
- Can the DH-SD5A425GB-HNR automatically track people and vehicles?
Yes. The camera supports Auto Tracking 3.0 and can link supported IVS rules to PTZ movement so a detected target is followed automatically. Its perimeter functions classify human and vehicle targets, while Auto Patrol can move the camera to a target position and patrol through presets. Tracking performance depends on target size, contrast, speed, obstructions and commissioning.
- How far does the infrared illumination reach?
The DH-SD5A425GB-HNR uses four infrared illuminators with a listed maximum distance of 150 metres. Zoom-priority, automatic, manual and off controls adjust how the infrared system behaves. Actual usable range varies with target reflectivity, weather, haze, nearby surfaces, mounting height and ambient light, so the maximum figure should be treated as a planning reference rather than a guaranteed identification distance.
- Which intelligent analytics are supported?
The camera supports tripwire, intrusion, fence crossing, loitering, abandoned or missing objects, fast movement, parking, people gathering and human or vehicle alarm classification. It also provides face detection, video metadata, people counting, SMD 4.0, AcuPick and Auto Patrol. Some functions may compete for processing resources or require compatible back-end equipment, so the intended analytics should be selected during system design.
- Does the camera have built-in audio?
No built-in microphone or speaker is confirmed. The DH-SD5A425GB-HNR provides one line-level audio input and one line-level audio output through bare-wire connections, allowing compatible external audio equipment to be integrated. It supports several audio compression formats, but external microphones, speakers, amplifiers and installation cabling are not stated as included.
- What power, storage and alarm connections are available?
The camera supports 24V DC at 2.5A or PoE+ and consumes up to 21W with the illuminator, PTZ, heater and fan active. It accepts a microSD card up to 512GB and also supports FTP, SFTP and NAS storage. Connections include two alarm inputs, one alarm output, one audio input and one audio output. The PFB305W wall bracket and 24V DC power adapter are listed as included.
- What should I confirm before ordering the DH-SD5A425GB-HNR?
Confirm the required overview and identification distances, mounting height, tracking rules, night coverage, recorder compatibility, bandwidth, storage retention, alarm wiring, external audio equipment and PoE+ or 24V DC power design. The camera weighs 4.7kg and requires suitable structural support. Security Wholesalers can review the proposed position and system layout to identify likely zoom, power, mounting or analytics limitations before installation.
