Product SKU: DH-IPC-HFW2431DG-4G-SP-EAU-B
Product Overview
Built for remote and off-grid outdoor locations where running mains power or ethernet cable is not practical, the Dahua IPC-HFW2431DG-4G-SP delivers 4MP surveillance without any fixed infrastructure. This solar-powered bullet camera combines a monocrystalline solar panel with a 10,000 mAh rechargeable lithium battery and 4G LTE connectivity, making it fully self-contained from day one. Featuring a 2.8 mm fixed lens with a 114-degree viewing angle, it covers wide approaches such as site entrances, farm gates, and unmanned yards. Equipped with a built-in PIR sensor, the camera detects human body heat to trigger sound and light alarms, reducing activations caused by non-human movement. It also includes a built-in microphone and speaker supporting two-way talk, plus dual storage via an 8 GB eMMC chip and a MicroSD slot supporting cards up to 256 GB. With an IP67 rating and a sleep mode capable of sustaining operation through approximately 10 consecutive overcast days, the IPC-HFW2431DG-4G-SP is well suited to construction sites, rural properties, and any location where cabling is not an option.
Key Capabilities
Solar Power with 10,000 mAh Battery
A 5 W monocrystalline solar panel charges a 10,000 mAh lithium battery, providing completely wire-free operation. Battery reserves support around 10 days of standard use in sleep mode during consecutive overcast days, removing dependence on grid power entirely.
4G LTE Connectivity
Built-in 4G with support for FDD-LTE, TDD-LTE, WCDMA, and GSM bands configured for the EAU region allows the camera to transmit live video and alerts over a mobile network with no ethernet cabling required. P2P support simplifies remote viewing via mobile devices.
PIR Human Body Detection
The built-in passive infrared sensor detects heat signatures consistent with a human body rather than relying solely on pixel-level motion detection. This makes activations more specific to human presence, reducing unnecessary alarm events at outdoor locations exposed to moving vegetation or animals.
Dual Illumination: IR 50 m and Warm Light 30 m
Infrared illumination reaches 50 m for low-profile night monitoring, while a 30 m warm light option provides visible deterrence and colour detail at night. Alarm-linked illumination means the light activates in response to a PIR trigger rather than running continuously.
Two-Way Audio with Built-In Mic and Speaker
A built-in microphone and speaker allow real-time voice communication in both directions. Operators can listen to activity at the camera location and issue verbal responses or warnings remotely, which is particularly useful at unattended access points or temporary sites.
Dual Storage: eMMC and MicroSD
An onboard 8 GB eMMC memory chip provides a baseline storage buffer, while a MicroSD slot accepts cards up to 256 GB for extended local recording. This dual-storage approach keeps footage accessible even when 4G connectivity is interrupted.
Best For
- Remote Site Entrances Without Power: The solar panel and battery combination means the camera can be deployed at farm gates, rural property boundaries, or unmanned access points where no mains power is available.
- Construction Sites Requiring Temporary Coverage: The wire-free, self-contained design allows the IPC-HFW2431DG-4G-SP to be repositioned as a site evolves, with no permanent cabling investment.
- Locations Where Cabling is Cost-Prohibitive: Remote buildings, sheds, caravan parks, and rural outbuildings where trenching or aerial cable runs would be expensive are well suited to a camera that needs only a mounting point and cellular coverage.
- Sites Needing Active Deterrence: PIR-triggered sound and light alarms provide an immediate on-site response when human presence is detected, rather than recording only for later review.
Why Choose the IPC-HFW2431DG-4G-SP
The IPC-HFW2431DG-4G-SP addresses a specific problem that standard IP cameras cannot: how to provide 4MP video surveillance at a location with no power outlet and no network cable. Rather than treating solar and 4G as afterthoughts, Dahua has built them into the camera body itself, pairing a 5 W monocrystalline solar panel with a 10,000 mAh battery that sustains operation through roughly 10 consecutive overcast days in sleep mode. The PIR sensor adds a layer of targeted detection beyond standard motion zones, making alarm events more relevant to actual human activity at the site. Combined with two-way audio, dual local storage, and a 114-degree wide-angle view from the 2.8 mm fixed lens, this camera delivers a complete standalone monitoring solution with no installation dependencies beyond a suitable mounting surface and 4G signal. Available at Security Wholesalers, the IPC-HFW2431DG-4G-SP suits buyers who need a deployable camera that works from day one without any cabling infrastructure.
Buyer Decision Tips
Confirm 4G Coverage at the Installation Site: The IPC-HFW2431DG-4G-SP connects over the mobile network rather than Wi-Fi or ethernet. Before deploying, verify that the intended location has adequate 4G signal from a compatible carrier, as the EAU-region band configuration supports FDD-LTE B1/3/5/7/8/20/28 and TDD-LTE B38/40/41. A SIM card from a carrier with strong rural coverage in your area will directly affect live view reliability and alert delivery.
Consider Sun Exposure and Operating Temperature: Solar charging performance depends on the panel receiving adequate direct sunlight. Mount the camera where the solar panel faces toward maximum sun exposure throughout the day, avoiding shaded or north-facing positions in Australia. Also note the operating temperature range of 0 °C to +50 °C; this camera is not rated for environments that fall below freezing, so high-altitude or cold-climate sites should be assessed accordingly.

Ideal Use Cases
Farm and Rural Property Gates
Remote gate entrances on rural properties often lack power infrastructure. The solar panel and 4G connectivity allow the IPC-HFW2431DG-4G-SP to monitor vehicle and person access and deliver alerts directly over the mobile network without any cabling to the main building.
Construction Sites
Temporary surveillance on active construction sites is simplified when no fixed wiring is involved. The self-contained design means the camera can be relocated as the project progresses, and the PIR alarm with sound and light linkage provides an active on-site deterrent after hours.
Unmanned Outdoor Storage Areas
Plant hire yards, container storage, and rural machinery sheds that are not connected to building power benefit from a camera that charges itself. The 114-degree 2.8 mm lens captures a wide view of open storage areas, with dual local storage retaining footage even without connectivity.
Remote Recreational Properties
Cabins, holiday properties, and bush blocks visited intermittently are difficult to monitor with traditional cameras. The 10,000 mAh battery sustains operation during extended periods of low sunlight, and P2P connectivity allows owners to check live view remotely on a smartphone.
Temporary Event or Venue Security
Pop-up events, outdoor markets, and temporary venues can deploy this camera quickly at entry points without coordinating with electricians or network installers. Two-way audio adds communication capability at entry and exit points where staff may not always be present.
Choosing the Right Model
- Choose this model if: You need to monitor a location without access to mains power or ethernet cabling, and 4G mobile signal is available at the site. The IPC-HFW2431DG-4G-SP is purpose-built for this scenario, combining solar charging, battery backup, and cellular transmission in a single unit.
- Choose a different model if: You have reliable mains power and a wired network at the installation site. A standard PoE IP bullet camera will deliver higher sustained performance, more consistent bit rates, and broader operating temperature tolerance without the constraints of solar charging and 4G data usage costs.
- Choose a different model if: The site experiences temperatures below 0 °C, such as alpine locations or cold-climate storage. The IPC-HFW2431DG-4G-SP is rated to a minimum of 0 °C and is not suitable for sub-zero environments.
- Choose a different model if: You require optical zoom, varifocal adjustment, or a longer focal length to identify subjects at distances beyond what a 2.8 mm wide-angle lens provides. The fixed lens on this model is optimised for broad coverage rather than detail at distance.
FAQs
- How long will the battery last if the solar panel is not receiving sunlight?
In sleep mode, the 10,000 mAh battery is rated to sustain operation through approximately 10 consecutive overcast or rainy days. In general mode with 1 hour of remote live view per day, the battery cycle life is approximately 10 days. Actual duration will vary depending on how frequently alarms are triggered and how much live view is used.
- Does the IPC-HFW2431DG-4G-SP work with any SIM card?
The camera accepts a standard SIM card and supports multiple 4G frequency bands configured for the EAU region, including FDD-LTE B1/3/5/7/8/20/28 and TDD-LTE B38/40/41, as well as 3G WCDMA and 2G GSM fallback. Compatibility with your specific carrier should be verified against these band lists. A carrier with strong rural LTE coverage in your area will give the best results.
- What triggers the sound and light alarm?
The built-in PIR sensor detects human body heat and links the alarm activation to both the audible speaker and the warm light illuminator. Other alarm events that can be configured include motion detection, video tampering, audio detection, SD card errors, IP conflict, illegal access, and low battery alerts.
- What is the difference between sleep mode and general mode?
In sleep mode, the camera powers down non-essential functions between events to conserve battery, waking on PIR detection or scheduled intervals. General mode keeps the camera in a higher-readiness state suitable for more active monitoring but draws more power. Sleep mode is the recommended default for locations relying primarily on solar charging.
- How is footage stored if the 4G connection drops out?
The camera includes an onboard 8 GB eMMC memory chip that stores footage locally regardless of network status. A MicroSD card slot supports cards up to 256 GB for extended local recording. When connectivity is restored, the camera can resume normal operation and alert delivery without losing locally recorded footage.
- Can this camera be wall-mounted on an outdoor structure such as a fence post or shed wall?
Yes. The camera is rated IP67 for dust and water ingress protection, making it suitable for direct outdoor mounting. The bullet form factor includes a mounting bracket that attaches to walls, posts, or similar flat surfaces. Ensure the solar panel faces toward maximum sunlight exposure at the installation site for optimal charging.
- Is this camera compatible with Dahua NVRs or existing surveillance systems?
The IPC-HFW2431DG-4G-SP supports ONVIF Profile S and Profile G as well as CGI and P2P protocols, which means it can integrate with compatible Dahua NVRs and third-party systems supporting ONVIF. However, because it connects over 4G rather than a local network, integration with an NVR will depend on your specific network configuration and NVR’s ability to connect to cameras over a WAN. Contact Security Wholesalers if you need advice on integrating this camera into an existing recorder setup.
