Is the Dahua DH-SD49825GB-HNR still a current model?

No. Dahua’s official product page marks the DH-SD49825GB-HNR as EOL and places it in the discontinued PTZ camera category. Remaining stock, warranty handling, firmware availability and replacement options should be confirmed before purchase. Security Wholesalers can assist with checking availability and identifying a suitable current Dahua PTZ when long-term platform support or future expansion is important.

How much detail does the 25× optical zoom provide?

The 5–125mm motorised lens provides 25× optical zoom, changing the horizontal field of view from approximately 53.1° to 3.4°. Optical zoom places more image detail on distant subjects than digital enlargement, but identification performance still depends on distance, atmospheric conditions, lighting, camera stability, scene angle, target movement and the recorder or viewing platform.

How far does the infrared night vision reach?

Dahua specifies infrared illumination up to 100 metres using four IR illuminators. The camera can produce an image at 0 lux when IR is active. Actual usable distance varies with zoom position, target reflectivity, rain, fog, dust, mounting height and nearby surfaces. Highly reflective objects close to the camera can also cause overexposure and reduce distant night detail.

What intelligent analytics does the camera support?

The camera supports SMD 4.0, perimeter protection and human or vehicle alarm classification for supported rules. Listed IVS functions include tripwire, intrusion, fence crossing, loitering, abandoned or missing object, fast movement, parking, people gathering and other events. Analytics performance depends on mounting, calibration, scene complexity, firmware and compatible recorder or management-platform configuration.

Does the SD49825GB-HNR support face recognition?

Dahua lists face detection, tracking, snapshot optimisation, face-attribute extraction and comparison against up to five face databases containing a combined 10,000 faces. This is more capable than simple face detection, but it does not guarantee identity accuracy in every scene. Camera angle, face size, lighting, occlusion, database quality, privacy obligations and system configuration all affect results.

Does this PTZ provide automatic target tracking?

The official specification lists Auto Patrol rather than conventional continuous auto tracking. Auto Patrol can trigger an IVS rule, rotate the PTZ to the target position and patrol according to configured presets. It should not be described as unrestricted autonomous target following. Confirm the required behaviour in the current firmware and management platform before relying on it for incident response.

Can the camera use PoE and local storage?

Yes. The DH-SD49825GB-HNR supports IEEE 802.3at PoE or 12V DC at 3A, with maximum consumption of 20W under the listed full operating condition. It also supports a microSD card up to 512GB, FTP or SFTP and NAS storage. PoE switch capacity, cable distance, surge protection and storage-card endurance should be planned for the complete installation.

What should I check before installing this discontinued PTZ?

Confirm current stock and support status, NVR or VMS compatibility, required AI functions, network bandwidth, storage, PoE+ capacity and mounting hardware. The included PFB305W wall bracket must be fixed to a structure capable of supporting the camera and accessories. Also plan earthing, surge protection, cable sealing, privacy masking and safe elevated access before installation or maintenance.

Description

Product SKU: DH-SD49825GB-HNR

Product Overview

The Dahua DH-SD49825GB-HNR is an EOL 8MP Starlight WizSense network PTZ camera designed for long-range operator-controlled surveillance across large outdoor areas. Its 5–125mm motorised lens provides 25× optical zoom, moving from a 53.1° horizontal overview to a narrow 3.4° view for closer inspection of distant activity. Four infrared illuminators provide a specified night range of up to 100 metres, while the 1/2.8-inch sensor records up to 3840 × 2160 at 25/30fps. SMD 4.0, human and vehicle perimeter classification, face detection and database comparison add intelligent event handling. Continuous 360° pan, 300 presets, tours, patterns and scans support repeatable patrol coverage, with IP66 protection and IEEE 802.3at PoE for professional installations.

Key Capabilities

8MP 4K PTZ Imaging

The 1/2.8-inch 8MP CMOS sensor produces up to 3840 × 2160 video at 25/30fps for detailed overview and zoomed surveillance.

25× Optical Zoom

The 5–125mm motorised lens moves from a 53.1° horizontal overview to a narrow 3.4° view for closer examination of distant activity.

100m Smart IR

Four infrared illuminators provide a specified night range of up to 100 metres with zoom-priority, manual and Smart IR control.

WizSense Human and Vehicle Analytics

SMD 4.0 and perimeter-protection rules can classify supported human and vehicle targets to reduce alarms caused by irrelevant movement.

Face Detection and Comparison

Face capture, attribute extraction and database comparison are supported with up to five databases and a combined 10,000 enrolled faces.

Fast Programmable PTZ Control

Continuous 360° pan, 300 presets, eight tours, five patterns, five scans and preset speeds up to 240° per second support responsive coverage.

Best For

Large Outdoor Areas: Covers car parks, logistics yards, campuses and industrial compounds from an elevated PTZ position.
Long-Range Detail: The 25× optical zoom supports closer inspection of distant people, vehicles and incidents.
Night Surveillance: Starlight sensitivity and a specified 100m IR range support monitoring after dark.
Human and Vehicle Events: SMD 4.0 and perimeter classification help reduce alarms from irrelevant movement.
Compatible Legacy Systems: May suit existing Dahua deployments that already support this discontinued model and its analytics.

Why Choose the DH-SD49825GB-HNR

The DH-SD49825GB-HNR combines 4K imaging, substantial optical zoom and responsive PTZ control in a compact 160mm body. Its 25× lens and 100m IR provide useful reach across large sites, while SMD 4.0, perimeter protection and face analytics offer more targeted event handling than a conventional PTZ. Local microSD storage, PoE+, audio and alarm interfaces, ONVIF support and a supplied PFB305W wall bracket add installation flexibility. Supplied by Security Wholesalers, this EOL camera is most appropriate where compatibility with an existing system is already established and current stock, firmware support and replacement planning have been confirmed.

Buyer Decision Tips

Lifecycle Tip: This model is officially discontinued. Confirm stock, warranty handling, firmware availability, cybersecurity requirements and a supported replacement path before specifying it for a new long-term project.

Coverage Tip: A PTZ records only the direction it is viewing. Use fixed cameras for continuous evidence at critical entrances, gates or boundaries while the PTZ moves elsewhere.

Installation Tip: Verify PoE+ capacity, bandwidth, mounting strength, earthing, surge protection and cable sealing. Elevated PTZ installation and servicing should be completed by appropriately equipped personnel.

Warehouses and Logistics Yards

Presets, tours, perimeter analytics and 100m IR support coverage of loading areas, vehicle approaches and external boundaries.

Industrial Compounds

IP66 protection, surge resistance and a wide operating-temperature range suit demanding sites when mounting, earthing and corrosion exposure are addressed.

Campus and Precinct Monitoring

High-resolution overview, long-range zoom and human or vehicle classification support active monitoring of gates, paths and open spaces.

Face-Capture Checkpoints

Face detection and comparison can support controlled approaches where subject position, lighting and privacy requirements are carefully managed.

Existing Dahua WizSense Systems

May suit compatible legacy NVR or VMS environments that already support the model’s streams, analytics and PTZ controls, subject to EOL considerations.

Choosing the Right Model

Choose the DH-SD49825GB-HNR if: An existing compatible Dahua system specifically requires this EOL 8MP PTZ and support expectations are understood.
Choose a current-generation PTZ if: The project requires an active product lifecycle, newer firmware platform, current analytics or long-term expansion.
Choose a fixed camera if: Continuous recording of one critical view is more important than operator-controlled pan, tilt and zoom.
Choose a larger-zoom model if: The required subject distance and pixel density exceed what the 5–125mm lens can deliver.
Confirm analytics behaviour: Auto Patrol is an IVS and preset-based function and should not be assumed to provide unrestricted continuous target tracking.
