Product SKU: DH-SD49225XA-HNR
Product Overview
The Dahua DH-SD49225XA-HNR is a 2MP WizSense network PTZ camera designed for car parks, warehouses, farms, gates, yards and building perimeters where operators need both wide-area awareness and detailed long-range viewing. Its 4.8–120mm motorised lens provides 25x optical zoom, allowing the camera to move from a broad overview to a narrow view of a distant person, vehicle or access point. Starlight low-light technology, 120dB WDR and Smart IR illumination reaching up to 100 metres support surveillance across difficult daytime and night-time conditions. WizSense functions include perimeter protection with human and vehicle classification, SMD Plus, face detection and smart target capture. The camera also supports rapid PTZ movement, 300 presets, local microSD recording, PoE+ and external audio and alarm connections. This model is listed as discontinued, so current availability and replacement planning should be confirmed before purchase.
Key Capabilities
25x Long-Range Optical Zoom
The 4.8–120mm lens changes from a wide 62.8-degree horizontal view to a narrow 2.6-degree telephoto view. Unlike digital enlargement, optical zoom concentrates the camera’s available image detail on a smaller, more distant target before the image is recorded.
Fast and Flexible PTZ Movement
Endless 360-degree pan and a -15-degree to 90-degree tilt range allow operators to inspect different areas from one mounting position. The camera supports 300 presets, tours, patterns, scans, power-off memory and configurable idle actions for repeatable monitoring routes.
Starlight and 100m Smart IR
Starlight sensitivity assists in dim environments, while six infrared illuminators provide night vision to a stated maximum of 100 metres. Smart IR and zoom-priority control help adjust infrared output as the lens moves between wide and telephoto positions.
Human and Vehicle Event Filtering
Tripwire and intrusion rules support human and vehicle classification, helping reduce events caused by animals, leaves, changing light and other less relevant movement. SMD Plus provides additional human and vehicle filtering for motion-based alerts and footage review.
High-Frame-Rate 1080p Video
The camera records 1920 × 1080 video at up to 50 or 60 frames per second. This is useful for smoother review of moving vehicles, gates, loading areas and other scenes where motion detail is more important than ultra-high pixel resolution.
Edge Recording and System Integration
A microSD card slot supports local recording up to 256GB, while audio input, audio output, two alarm inputs and one alarm output support integration with compatible external devices. PoE+ or 12V DC power can be selected to suit the installation.
Best For
- Car Parks and Vehicle Entrances: The PTZ movement and 25x optical zoom allow an operator to inspect lanes, gates and distant vehicle activity.
- Warehouses and Loading Areas: High-frame-rate video, long-range infrared and configurable presets suit large operational spaces with regular movement.
- Farms and Rural Properties: The camera can move between gates, sheds, yards and distant approaches from one elevated position.
- Building Perimeters: Perimeter protection and human or vehicle classification support targeted monitoring of boundaries and access zones.
- Operator-Controlled Surveillance: Suitable for sites where security staff need to manually pan, tilt and zoom into developing activity.
Why Choose the DH-SD49225XA-HNR
The DH-SD49225XA-HNR is a practical choice when a fixed camera cannot provide both broad situational awareness and detailed long-range inspection. Its 25x optical zoom lets an operator examine distant gates, vehicles or activity without relying only on digital enlargement, while its fast PTZ movement and preset functions allow one camera to inspect several planned viewpoints. WizSense perimeter protection and SMD Plus provide more relevant human and vehicle events than conventional motion detection alone. The combination of Starlight sensitivity, 100-metre infrared, PoE+, edge storage and external audio or alarm interfaces also gives installers considerable system flexibility. Available through Security Wholesalers, this discontinued model is best suited to compatible replacement requirements or installations where remaining stock and future support have been confirmed.
Buyer Decision Tips
Coverage Tip: A PTZ camera only records the direction in which it is currently facing. Use fixed cameras alongside the PTZ when entrances, gates or other critical areas must remain continuously recorded while the PTZ is viewing another part of the site.
Tracking Tip: Automatic target tracking is not confirmed for this model. It supports manual movement, presets, tours, patterns and scans, but buyers requiring automatic person or vehicle tracking should select a model where smart tracking is explicitly specified.

Choosing the Right Model
- Choose this model if: You need 25x optical zoom, fast PTZ control, 100-metre infrared and human or vehicle event filtering at 1080p.
- Choose a higher-resolution PTZ if: Greater pixel detail is more important than this model’s 50/60fps 1080p performance.
- Choose a smart-tracking PTZ if: The camera must automatically follow a detected person or vehicle without continuous operator control.
- Add fixed cameras if: Critical entrances or boundaries must remain continuously recorded while the PTZ is viewing another direction.
- Choose a current-generation model if: Long-term product availability, current firmware support or future system standardisation is a priority.
FAQs
- Is the Dahua SD49225XA-HNR suitable for car parks and large outdoor areas?
The SD49225XA-HNR is well suited to car parks, yards, warehouses, farms, gates and building perimeters where operators need to move between a broad overview and a tightly zoomed target. Its endless pan, -15° to 90° tilt range, 25x optical zoom and 100-metre infrared illumination provide flexible coverage. A PTZ does not continuously view every direction at once, so fixed cameras may still be required for uninterrupted coverage of critical areas.
- How far can the 25x optical zoom see?
The 4.8–120mm lens provides 25x optical zoom, changing the horizontal field of view from approximately 62.8° to 2.6°. Dahua lists DORI planning distances at the telephoto end of 1,613 metres for detection, 646 metres for observation, 323 metres for recognition and 161 metres for identification. These are planning references rather than guaranteed forensic results, as actual performance depends on lighting, weather, movement, mounting stability and scene contrast.
- Does the SD49225XA-HNR support automatic tracking?
Automatic tracking is not confirmed in the supplied specification for the SD49225XA-HNR, so it should not be purchased on the assumption that it will automatically follow a detected person or vehicle. The camera supports manual PTZ control, 300 presets, tours, patterns, scans and idle-motion actions. Choose a model with explicitly confirmed smart tracking when automatic target following is a required part of the installation.
- What WizSense analytics are available on this PTZ camera?
The SD49225XA-HNR supports tripwire and intrusion rules with human and vehicle classification, SMD Plus, face detection and smart capture of people, motor vehicles and non-motor vehicles. It also supports abandoned-object and missing-object detection. These functions can reduce irrelevant event review, but their effectiveness depends on camera position, zoom level, target size, lighting and correctly configured detection rules.
- How does the SD49225XA-HNR perform at night?
The camera uses Starlight imaging with a stated minimum illumination of 0.005 lux in colour and 0.0005 lux in black and white under the specified conditions. Six infrared illuminators provide Smart IR coverage up to 100 metres, and the camera can prioritise illumination according to zoom position. It is an infrared PTZ rather than a white-light full-colour night camera, so very dark scenes normally switch to monochrome IR imaging.
- Can the camera record audio or provide two-way talk?
The SD49225XA-HNR provides one audio input and one audio output, but a built-in microphone and built-in speaker are not confirmed. Audio recording or two-way communication therefore requires compatible external audio equipment and correct system configuration. The camera should not be described as having standalone two-way audio. Local laws, workplace policies and privacy requirements should also be considered before enabling audio capture.
- Can the SD49225XA-HNR be powered using PoE?
Yes. The camera supports IEEE 802.3at PoE+, allowing power and network data to share one Ethernet cable from compatible PoE+ equipment. It can alternatively use a 12V DC, 3A supply. Maximum stated power consumption is 22W with infrared operating, so the PoE switch, injector, cabling and total power budget must support the required load rather than being sized only for standard low-power PoE cameras.
- Is the Dahua SD49225XA-HNR discontinued?
Yes. Dahua lists the SD49225XA-HNR as an end-of-life product. Buyers sourcing remaining stock through Security Wholesalers should confirm current availability, firmware requirements, mounting accessories and whether a current-generation replacement is more appropriate for a new installation. The discontinued model can still suit a compatible existing system or a specific replacement requirement, but long-term standardisation should account for future stock and support availability.
