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 mains power and network cable are simply not available at the install location, the Hikvision DS-2DE5425IWG-K/4G is the camera that removes both constraints in one unit. This is a 4G-connected, solar-powered PTZ built for remote properties, rural infrastructure, construction sites, and off-grid locations where running conduit to a camera position is either cost-prohibitive or physically impractical. The included solar panel and built-in rechargeable battery keep the camera operational without any grid connection, while the 4G radio handles video transmission and remote control. The 25x optical zoom and 120-metre IR range mean operators can remotely inspect specific areas of a large site - paddock gates, water points, machinery yards - without physically attending. If you are specifying surveillance for a location where "there is no power and no cable" has killed every other option, this unit is built specifically for that problem.

What This Camera Actually Does

Who Buys This Model

• Rural and Remote Property Owners: Farmers and station managers monitoring paddock gates, water infrastructure, or outbuildings where there is no reticulated power and cellular coverage exists.
• Construction Site Managers: Temporary installs on active sites where mains power connections are not yet established and the camera position changes as the build progresses.
• Mining and Resources Operators: Monitoring of remote equipment laydown areas, haul road entries, or site perimeters where cable infrastructure is not viable.
• Infrastructure and Utility Managers: Water authorities, councils, and utilities needing to monitor pumping stations, reservoirs, or remote road infrastructure without trenching power or fibre.
• Security Integrators Servicing Off-Grid Sites: Installers specifying a camera that combines connectivity, power, storage, and PTZ control into a single self-contained unit to reduce site complexity and ongoing maintenance.

Honest Assessment

The DS-2DE5425IWG-K/4G genuinely solves the off-grid surveillance problem. The combination of solar power, built-in battery, 4G connectivity, onboard 256GB storage, 25x optical zoom, and 120-metre IR in a single IP66-rated housing means a complete, self-contained surveillance point can be deployed at a remote location with a pole mount, a SIM card, and a few hours of installation time. The 4MP sensor and 25x optical zoom deliver the image detail needed to distinguish individuals and read vehicle registration at real-world distances. Where it has limitations: sustained cloud cover in regions with low solar irradiance can affect battery endurance, so sites in Tasmania or frequently overcast coastal areas warrant checking panel output and power consumption balance carefully. This camera is also dependent on 4G signal quality - a site with marginal or intermittent coverage will experience unreliable streaming. It is not a substitute for a wired PTZ where infrastructure exists. The DS-2DE5425IWG-K/4G is available through Security Australia.

Before You Buy

Quick Fit Check

• Good match if: Your install location has no mains power and no cable infrastructure - the solar panel, battery, and 4G radio make this a self-contained unit that requires only a mounting point and a SIM card.
• Good match if: You need to remotely inspect specific areas of a large outdoor site - the 25x optical zoom and 120-metre IR allow detailed observation at distances where fixed cameras would require multiple units.
• You may need a different model if: Your site has reliable mains power and network infrastructure - a wired PTZ camera will offer more consistent performance, higher sustained resolution streaming, and no dependency on solar charge levels or cellular signal.

Real-World Scenarios

How It Compares

• Choose this if: Your install location has no mains power and no network cable - no other PTZ type combines solar power, onboard battery, 4G connectivity, 256GB local storage, and 25x optical zoom in a single IP66 housing.
• You may need a different model if: Mains power and a wired network are available at the install point - a wired PTZ will offer more consistent high-bitrate streaming, PoE simplicity, and no dependency on solar charge cycles or cellular coverage.
• Pairs well with: A 4G-compatible VMS or cloud recording platform that accepts RTSP streams, allowing centralised monitoring of multiple self-contained solar PTZ deployments across a property or portfolio of sites.

Common Questions

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

   Yes. The DS-2DE5425IWG-K/4G is specifically designed to operate with no mains connection and no network cable. The included solar panel charges the built-in rechargeable battery during daylight, and the built-in 4G radio handles all data transmission. You need a compatible SIM card from a 4G carrier with coverage at the install location - nothing else.

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

   Footage continues to be recorded locally. The 256GB eMMC storage is built into the camera and operates independently of the 4G connection. When the 4G link is restored, remote access to footage resumes. The local storage buffer means a loss of cellular signal does not result in a loss of recording.

3. What is the pan and tilt range, and does the camera support preset positions?

   The DS-2DE5425IWG-K/4G is a full PTZ unit with 360-degree continuous pan and tilt movement, controllable remotely via the 4G connection. Preset positions are supported, allowing operators to define specific patrol points or named views that the camera can return to automatically or on command. The 25x optical zoom is also controllable remotely, enabling operators to move and zoom into specific areas of interest without attending the site.

4. Will this camera work through an Australian winter with reduced sunlight?

   It depends on your location and panel orientation. The camera drops to 0.3W in sleep mode to conserve battery charge when inactive, which extends operational time during low-solar periods. The 12V 1A reverse power supply input allows an external DC source to supplement charging if solar input is insufficient. Sites in southern Australia - particularly Tasmania or the southern highlands - should factor in winter solar irradiance levels for the specific latitude when assessing viability without backup charging.

5. Does the 25x optical zoom affect image quality at maximum zoom?

   No - optical zoom does not degrade image quality the way digital zoom does. The 25x optical zoom physically adjusts the lens, maintaining the full 4MP (2560 x 1440) sensor resolution at all zoom levels. Digital zoom, which simply crops and enlarges the sensor image, is not required to reach the 25x figure. This means detail captured at maximum optical zoom is substantially more usable than the equivalent digital zoom on a fixed-lens camera.

6. Can I use two-way audio to communicate with someone at the camera location?

   Yes. The camera has both a built-in microphone and a built-in speaker, enabling full two-way audio over the 4G connection. An operator monitoring remotely can speak through the camera to anyone within range of the speaker, and hear audio captured by the microphone. This is useful for verbal warnings, site communication, or confirming the identity of individuals at a remote access point without a separate intercom system.

7. Is the Wi-Fi AP mode useful for setup or ongoing remote monitoring?

   The Wi-Fi AP mode (Channel 11) is primarily useful during initial configuration and local setup. It allows a technician to connect directly to the camera from a laptop or tablet without needing the 4G SIM to be active, simplifying first-time configuration. For ongoing remote monitoring and PTZ control, the 4G connection is the primary data path. If you have questions about compatibility with your specific 4G carrier or VMS platform, the team at Security Australia can assist with configuration advice.
