Product Overview
Wide-area surveillance at locations without fixed network infrastructure is the core purpose of the DH-SD49425XB-HNR-G, a 4MP outdoor speed dome PTZ camera with an integrated 4G modem supporting LTE, WCDMA and GSM connectivity. Rather than requiring a cabled data link or on-site router, it connects directly over a mobile network, making it a practical choice for remote sites, temporary deployments and locations where running Cat5e or fibre is not feasible. The 25x optical zoom covers a focal range of 4.8 mm to 120 mm, allowing operators to observe detail across large outdoor distances. Starlight low-light performance delivers colour imaging down to 0.005 Lux, backed by 4 IR illuminators with a range of 100 m. AI capabilities include Perimeter Protection with human and vehicle classification, SMD Plus, Face Detection and Smart Capture. PoE+ (802.3at) is also supported as a wired alternative. IP66 weatherproofing and a -40°C to +70°C operating range suit it to exposed outdoor environments. Note: this camera is listed as end-of-life (EOL).
Key Capabilities
Integrated 4G Connectivity
The built-in 4G modem supports LTE FDD, WCDMA and GSM bands, allowing the camera to transmit video over a mobile network. This eliminates the need for a physical data connection at the installation point, which is essential for remote paddocks, construction sites and temporary monitoring positions.
25x Optical Zoom with SmartIR
A 25x optical zoom spans 4.8 mm to 120 mm (F1.6 to F4.0), covering a horizontal field of view from 60° wide-angle down to 2.5° telephoto. SmartIR automatically adjusts IR intensity across the zoom range to prevent image washout, maintaining usable detail at both short and long distances.
Starlight Low-Light Performance
The 1/2.8″ STARVIS CMOS sensor achieves colour imaging at 0.005 Lux and monochrome at 0.0005 Lux. Combined with a maximum aperture of F1.6, the camera retains usable colour footage in very low ambient light before switching to IR-assisted black and white when light drops to zero.
Perimeter Protection with Human and Vehicle Classification
AI-driven Perimeter Protection supports tripwire and intrusion zone rules with target classification by human or vehicle. The system filters out triggers caused by animals, foliage movement and light changes, directing alerts toward events that are more likely to require a genuine response.
SMD Plus
Smart Motion Detection Plus classifies moving objects as human or vehicle before triggering a motion event. This reduces the volume of motion alerts generated by non-relevant movement, making it easier to locate meaningful footage during playback review without sifting through large amounts of irrelevant recordings.
Full PTZ Movement Range and Preset System
The camera supports 360° continuous pan and -15° to 90° tilt with auto-flip. Up to 300 presets, 8 patrol tours (each covering up to 32 presets), 5 scan patterns and idle motion configuration give operators a comprehensive framework for covering large sites with automated or manual control.
Best For
- Remote Sites Without Cabled Network: The integrated 4G modem allows deployment at locations where running a physical data cable is impractical, including rural properties, unmanned substations and temporary work sites.
- Wide-Area Outdoor Perimeter Monitoring: The 25x optical zoom combined with a DORI detection range of 2540 m makes it suited to monitoring large outdoor areas such as industrial yards, open paddocks and port access roads from a single mounting position.
- Sites Needing AI-Filtered Alerts: Perimeter Protection and SMD Plus together reduce the number of nuisance alerts caused by animals or environmental movement, making the camera useful at sites where accurate event filtering matters more than raw sensitivity.
- Exposed Outdoor Installations in Extreme Temperatures: An operating range of -40°C to +70°C with IP66 weatherproofing and TVS 6000V lightning and surge protection makes this camera suited to environments with harsh weather, temperature extremes or electrical storm risk.
Why Choose the DH-SD49425XB-HNR-G
The DH-SD49425XB-HNR-G occupies a specific position in the PTZ market: a 4MP speed dome that does not depend on a wired network connection to operate. The integrated 4G modem with LTE, WCDMA and GSM support is not a plug-in module but a built-in feature, reducing the complexity and failure points of a separate cellular router setup. The 25x optical zoom with SmartIR, Starlight sensor and 100 m IR range give it genuine long-distance capability, while AI features including Perimeter Protection, SMD Plus and Smart Capture go beyond basic motion detection. A wider IP66 dome PTZ without 4G would require running Cat5e or fibre to every location, which is not always viable. The combination of mobile network flexibility and optical zoom range in a single sealed enclosure is what separates this unit from a standard wired PTZ. It is available through Security Wholesalers. Note that this model is listed as end-of-life (EOL) and stock is limited.
Buyer Decision Tips
4G SIM and Data Plan: This camera requires a SIM card with a suitable mobile data plan to use its 4G function. Check that the supported LTE FDD bands (Band 1, 2, 3, 4, 7) align with the frequency bands your preferred Australian carrier uses at the installation site. Coverage can vary significantly in rural and remote locations, so confirming signal strength at the exact mounting point before purchase is strongly recommended.
EOL Status and Long-Term Support: This model is confirmed as end-of-life (EOL). If you are specifying this camera for a long-term installation or a project requiring ongoing product availability, consider whether the listed replacement model better suits your requirements before committing to this unit. For short-term or temporary deployment where stock is on hand, the confirmed specifications remain fully applicable.

Ideal Use Cases
Remote Rural and Agricultural Sites
The 4G modem with LTE/WCDMA/GSM support allows deployment at properties without fixed broadband infrastructure. Combined with Micro SD card storage up to 256 GB, the camera can record locally even if the mobile connection drops temporarily.
Construction Sites and Temporary Monitoring
A relocatable 4G PTZ avoids the cost and disruption of cabling a temporary site. The IP66 rating, -40°C to +70°C operating range and TVS 6000V surge protection suit open-air construction environments where conditions can vary significantly.
Industrial Yards and Large Perimeters
The 25x optical zoom with a DORI detection distance of 2540 m and observation range of 1016 m means a single camera position can cover a large industrial yard perimeter. Perimeter Protection with human and vehicle classification helps filter alerts to relevant intrusion events.
Unmanned Critical Infrastructure
Power substations, water treatment sites and communications towers that are unmanned and remote benefit from the combination of 4G connectivity, alarm I/O (2 inputs / 1 output), and AI event triggers such as intrusion detection and object abandoned/missing analytics.
Car Parks and Open Outdoor Areas
Smart Capture automatically snapshots humans, motor vehicles and non-motor vehicles for event review. Combined with 300 preset positions and 8 automated patrol tours, the camera can cycle through defined viewing angles to maintain coverage across a large open car park or access road network.
Choosing the Right Model
- Choose this model if: You need a 4G-enabled PTZ speed dome with 25x optical zoom and AI perimeter analytics for a remote or temporary site, and have access to existing stock of this unit at an acceptable price given the EOL status.
- Choose a different model if: You are specifying for a new long-term installation. This model is confirmed EOL, and the listed replacement includes the same 4G connectivity with the addition of an active deterrence siren and speaker. For projects requiring ongoing parts availability or extended support, the replacement model is the more forward-viable option.
- Choose a wired PTZ instead if: The installation site has reliable Cat5e or fibre infrastructure available, as a wired PTZ avoids dependence on mobile carrier coverage and data costs, and typically provides more stable network performance for high-bitrate 4MP streaming.
FAQs
- Does the DH-SD49425XB-HNR-G require a SIM card to use the 4G function?
Yes. The 4G connectivity requires a SIM card with an active mobile data plan. The camera supports LTE FDD bands 1, 2, 3, 4 and 7, WCDMA bands 1 and 2, and GSM at 1800 MHz and 1900 MHz. You should confirm that your preferred carrier operates on the supported LTE bands at the intended installation site before deploying the camera.
- Can the camera still operate if the 4G connection drops out?
Yes. The camera supports local Micro SD card storage of up to 256 GB. If the mobile connection is interrupted, it can continue recording to the SD card. It also supports NAS storage if a local wired network is available. PoE+ (802.3at) can be used as the primary network and power connection if 4G is not needed at a particular site.
- What does Perimeter Protection actually do on this camera?
Perimeter Protection uses AI to monitor defined zones for tripwire crossings and intrusion events. It classifies detected objects as human or vehicle before triggering an alarm, and suppresses triggers caused by animals, blowing leaves and changing light conditions. This reduces the volume of nuisance alerts compared to standard motion detection at the same sensitivity level.
- What is the effective IR range and does it adjust with zoom?
The camera has 4 IR illuminators with a rated range of 100 m. SmartIR automatically adjusts the IR output intensity as the zoom level changes, which prevents overexposure of nearby subjects when zoomed in and maintains adequate illumination at longer distances when zoomed out.
- Is this camera suitable for use in extreme outdoor temperatures?
Yes. The operating temperature range is confirmed as -40°C to +70°C, which covers most Australian outdoor environments including cold alpine areas and hot inland sites. The IP66 rating protects against dust ingress and water jets, and TVS 6000V lightning and surge protection is built in.
- Does this camera support two-way audio?
The camera has 1 audio input port and 1 audio output port. However, a built-in microphone and built-in speaker are not confirmed in the product specifications. The audio ports allow connection of external audio devices, but this does not constitute built-in two-way audio capability out of the box.
- This model is listed as EOL. Should I still buy it?
The DH-SD49425XB-HNR-G is confirmed as end-of-life. If you have an immediate requirement and stock is available at a suitable price, the confirmed specifications remain fully valid for deployment. For new long-term projects or multi-camera installations requiring ongoing product availability, speaking with the team at Security Wholesalers about the listed replacement model would be the more practical approach before committing to this unit.
