Hikvision DS-2DE5425IWG-K/4G 4MP 4G Solar PTZ Camera, 25x, 256GB, Includes Solar Panel, Battery, IR, IP66

Model: DS-2DE5425IWG-K/4G

Who This Is For

When installing in a location with no mains power is the priority, the Hikvision DS-2DE5425IWG-K/4G is built specifically for that challenge. This is a 4MP 4G solar PTZ camera that arrives as a complete off-grid package - solar panel, built-in rechargeable battery, and 256GB of onboard eMMC storage all included. Connectivity runs entirely over 4G, meaning no cabling to a network, no trenching, and no electrician needed. The 25x optical zoom and 120-metre IR range make it suited to wide-open sites where the camera may be positioned at significant distance from the area being monitored. Remote locations including rural properties, construction sites, unmanned substations, temporary event sites, and infrastructure assets along highways or rail corridors are the primary use cases. If you need PTZ capability and wide-area coverage without any dependence on fixed power or fixed data infrastructure, this model is built for that scenario.

What This Camera Actually Does

Who Buys This Model

• Construction Site Managers: Monitoring unmanned sites during nights and weekends where running mains power to a camera position is impractical. The solar-battery system and 4G transmission mean no site infrastructure is required.
• Rural and Agricultural Property Owners: Covering large paddocks, gate entries, or water infrastructure kilometres from the homestead. The off-grid design and 256GB local storage remove any dependence on a local network.
• Infrastructure and Utilities Operators: Deploying temporary or permanent surveillance at substations, pumping stations, or remote assets along corridors where cellular coverage exists but mains power does not.
• Event and Temporary Site Security: Short-term deployments where cabling infrastructure cannot be justified. The self-contained solar kit can be mounted, connected to a 4G SIM, and operational without any site works.
• Security Integrators Specifying Off-Grid PTZ: Installers who need a manufacturer-complete solar PTZ solution with local storage and 4G included in a single SKU, rather than assembling components from multiple suppliers.

Honest Assessment

The DS-2DE5425IWG-K/4G does something genuinely useful: it delivers PTZ capability, 4MP resolution, 25x optical zoom, 120-metre night vision, and 256GB of local storage on a site with no mains power and no network - everything ships as one package. The 0.3W sleep mode power draw is well suited to the solar-battery system, and IP66 weatherproofing with heating glass makes it appropriate for demanding Australian outdoor conditions. Available through Security Australia, this model is a legitimate option for remote deployments that would otherwise require significant infrastructure investment.

Where this camera has limits: PTZ performance depends on cellular latency, so real-time pan and tilt control over 4G will not feel as responsive as a wired PTZ on a local network. Solar output is also location and season-dependent - sites with limited sun exposure in winter months will need careful assessment before committing to solar-only power. If you require faster PTZ response times or are installing where mains power is available, a wired PoE PTZ camera will give better operational performance.

Before You Buy

Quick Fit Check

• Good match if: You are monitoring a remote site with no mains power and need PTZ control with 25x optical zoom - the solar panel, battery, and 4G connectivity in this package eliminate the need for any fixed power or network infrastructure on site.
• Good match if: Your site has no NVR and no local network, and you need footage stored on the camera itself - the 256GB onboard eMMC storage handles local recording independently without any additional hardware.
• You may need a different model if: Mains power is available at your install point and low-latency PTZ control is a priority - a wired PoE PTZ camera will deliver faster and more consistent pan, tilt, and zoom response than a 4G-dependent model.

Real-World Scenarios

How It Compares

• Choose this if: Your installation site has no mains power and no wired network, and you need PTZ capability with 25x optical zoom and local storage - the complete solar and 4G package makes this viable where no wired PTZ could be deployed.
• You may need a different model if: Mains power is available and PTZ responsiveness is critical to your operation - a wired PoE PTZ camera eliminates the cellular latency that affects real-time pan, tilt, and zoom control on this model. Browse the PoE PTZ range at securityaustralia.com.au for options.
• Pairs well with: A 4G-compatible NVR or cloud video management platform that accepts RTSP streams from cellular cameras, allowing centralised recording and multi-camera management across multiple off-grid sites from a single interface.

Common Questions

1. Does this camera work without any mains power at all?

   Yes. The DS-2DE5425IWG-K/4G is designed to operate entirely without mains power. The included solar panel charges the built-in rechargeable battery during daylight, and the camera's sleep mode draws only 0.3W, which allows the battery to sustain operation through nights and low-sunlight periods. No external power connection of any kind is required for standard operation.

2. Is a SIM card included, and which carriers does the 4G work with?

   No, a SIM card is not included with the camera. You will need to source and activate a compatible 4G SIM separately. The camera uses standard 4G LTE connectivity. Carrier compatibility depends on the SIM card fitted and the frequency bands supported by this model - confirm the supported 4G bands against your preferred carrier's network frequencies before purchasing.

3. How does the 25x optical zoom work over a 4G connection - will there be lag when controlling it remotely?

   Yes, there will be some latency. PTZ control commands travel over the 4G cellular network, and response time depends on cellular signal quality and network congestion at the install location. In strong 4G coverage areas, latency is typically manageable for security monitoring purposes, but it will not match the near-instant response of a wired PTZ camera on a local PoE network. For applications requiring very rapid PTZ repositioning, a wired PTZ is a better fit. The 25x optical zoom itself is a full optical zoom mechanism and does not degrade image quality regardless of connection type.

4. What happens to recorded footage if the 4G connection drops out?

   Footage continues recording to the 256GB onboard eMMC storage. The local storage operates independently of cellular connectivity, so an outage in 4G coverage does not cause a gap in the local recording. Once cellular connectivity is restored, remote access to footage and live view resumes. This is one of the key practical advantages of the built-in eMMC storage in this model - it functions as a full local recorder rather than just a buffer.

5. Will this camera work through an Australian winter in southern states where sunlight hours are reduced?

   It depends on the specific location and panel orientation. The 0.3W sleep mode draw is designed to extend battery life significantly during low-sunlight periods, and the camera's dual operating modes allow it to conserve power when full performance is not needed. However, in locations with extended overcast periods or very low winter sun angles - particularly southern Victoria, Tasmania, and parts of South Australia - solar generation may be insufficient to maintain continuous full-performance operation without careful panel placement and angle optimisation. A site-specific solar assessment is recommended for these regions before committing to this model.

6. Does this camera support preset positions and auto-patrol for the PTZ?

   Yes. The camera supports PTZ preset positions and patrol functionality, which are standard features of the DS-2DE5425IWG series. Operators can configure the camera to automatically cycle through defined positions - useful for unattended sites where a fixed coverage pattern is needed without manual intervention. The number of configurable presets and patrol paths should be confirmed in the full product datasheet for this specific 4G variant, as the stocked version at Security Australia includes the camera's management software compatibility with Hikvision's iVMS-4200 and Hik-Connect platforms.

7. What are the pan and tilt range limits on this camera?

   The DS-2DE5425IWG-K/4G is a speed dome PTZ platform. Standard pan range for this series is 360 degrees continuous, with tilt movement covering from 0 to -90 degrees (horizon to straight down). This gives the camera complete horizontal coverage from a single fixed mount position, which is particularly useful on a pole or elevated post where repositioning the physical camera mount is not possible. Confirm the exact tilt limits against the full Hikvision datasheet for this specific model variant before specifying in applications requiring precise tilt angle planning.

8. Can this camera be connected to an existing Hikvision NVR on the same network?

   Not directly in an off-grid 4G deployment. Because the camera connects via cellular rather than a local network, it cannot be added to an NVR via the standard LAN discovery process. It can be integrated with compatible cloud-based or remote NVR setups that accept IP camera streams over the internet, but this requires specific configuration. If connecting cameras to a local Hikvision NVR is a requirement, a wired PoE camera on the same network segment is the appropriate choice.
