The Dahua DH-IPC-HFW2441DG-4G-SP-B-MAX is a 4MP Smart Dual Light 4G solar bullet camera designed for farms, construction sites, remote properties, equipment yards and other locations without convenient fixed power or internet infrastructure. Its 1/3-inch CMOS sensor records at up to 2560 × 1440 and 15fps through a fixed 3.6mm lens, while the integrated PIR sensor and SMD help identify relevant human or vehicle activity. AOV mode provides low-frame-rate continuous recording and increases the frame rate when an event wakes the camera. The built-in 64Wh lithium iron phosphate battery is charged by an adjustable 10.5W monocrystalline solar panel, with multiple operating modes available to balance battery endurance and recording coverage. Smart Dual Light provides up to 30m infrared and 20m warm-light illumination, while the built-in microphone, speaker and sound-and-light warnings support two-way talk and active deterrence. The IP67 housing suits properly installed outdoor applications.
Key Capabilities
4MP Solar-Powered Surveillance
The camera captures 2560 × 1440 video at up to 15fps and combines a built-in 64Wh battery with an adjustable 10.5W solar panel. This supports surveillance at sites where installing mains power, PoE switches or long network cables would be difficult.
AOV Always-On Video Mode
AOV records at a low frame rate during inactive periods and changes to a higher frame rate when a person or vehicle event occurs. This provides continuous video coverage while using substantially less power than full-time performance mode.
4G and Wired Connectivity
The built-in cellular module connects through a compatible regional 4G network and active SIM, while the 10/100Mbps Ethernet port provides an alternative wired connection. Carrier bands and mobile-data coverage must be verified at the installation location.
Smart Dual Light Imaging
Infrared illumination reaches up to 30m for discreet monochrome monitoring, while the 20m warm light can activate when a target appears. This allows the camera to capture colour event footage while limiting unnecessary continuous visible lighting.
Sound and Light Active Deterrence
Supported alarm events can activate the warm light and audible warnings through the built-in speaker. The camera provides selectable warning voices and supports importing customised audio to discourage trespassing or suspicious activity.
PIR Detection and Two-Way Talk
The integrated PIR sensor detects body heat and helps wake the camera quickly, while SMD supports more precise event detection. A built-in microphone and speaker allow configured users to listen and speak through the compatible mobile application.

Why Choose the DH-IPC-HFW2441DG-4G-SP-B-MAX
The DH-IPC-HFW2441DG-4G-SP-B-MAX combines the camera, wide-temperature battery, adjustable solar panel and 4G connectivity in one integrated outdoor system. Unlike a basic battery camera that records only short motion clips, its AOV mode can maintain low-frame-rate continuous recording and increase the frame rate when relevant activity is detected. The PIR sensor, SMD, Smart Dual Light and sound-and-light warnings provide a more proactive response around remote assets, while built-in audio supports live communication through the mobile app. Available through Security Wholesalers, this model is best selected after assessing sunlight, mobile signal, daily event frequency and required recording mode. Its maximum frame rate is 15fps, and reliable solar operation cannot be guaranteed at heavily shaded locations.
Buyer Decision Tips
Solar and Battery Tip: Battery endurance figures are based on specific operating assumptions. Frequent live viewing, weak 4G signal, high event activity, deterrence playback, cold conditions and insufficient sunlight can increase consumption and reduce the available operating time.
4G Compatibility Tip: Confirm the supplied regional variant and its LTE bands against the chosen mobile provider. An active SIM and suitable data plan are required, and neither mobile coverage nor carrier compatibility should be assumed from the camera model alone.

Choose this model if: The site has suitable sunlight and 4G coverage but no convenient fixed power or internet connection.
Choose AOV mode if: Continuous low-frame-rate recording is required with higher-frame-rate event capture.
Choose performance mode if: Continuous full operating performance is more important than extended battery endurance.
Choose a wired PoE camera if: Reliable network cabling and central power are available and higher frame rates or broader integrations are required.
Reassess the location if: The solar panel will be shaded for long periods or the mobile signal is weak or unstable.
FAQs
Can the DH-IPC-HFW2441DG-4G-SP-B-MAX operate without mains power or PoE?
The camera is designed around its integrated 64Wh lithium iron phosphate battery and 10.5W monocrystalline solar panel, so normal operation does not require PoE. Solar charging performance depends on daily sunlight, panel angle, temperature, event frequency and mobile signal quality. A 12V DC input can charge the battery from an external solar source, while the USB Type-C port supports temporary charging from a suitable power source.
How does AOV mode provide 24/7 recording with low power consumption?
AOV, or Always-On Video, records continuously at a low frame rate during inactive periods and changes to a higher frame rate when a person or vehicle event wakes the camera. Dahua lists AOV consumption at 0.26W, which is higher than the two standby modes but substantially lower than performance mode. Continuous results still depend on battery charge, sunlight, event frequency, network conditions and microSD capacity.
How long can the built-in 64Wh battery operate without solar charging?
Dahua lists up to 76 days in ultra power-saving mode with no trigger recording, 56 days in power-saving mode with 30 daily alarms under 15 seconds, 10 days in AOV mode under the same event assumption and two days in performance mode with continuous recording. These are reference figures rather than guaranteed site runtimes. Temperature, 4G signal, live viewing, deterrence use and event frequency can reduce endurance.
Which 4G networks and SIM cards are supported?
The exact LTE bands depend on the regional camera variant. The official specification lists an EAU/EUR version using FDD-LTE bands 1, 3, 5, 7, 8, 20 and 28, and a Latin American version using bands 2, 3, 4, 5, 7, 8, 28 and 66. Confirm the supplied variant, local carrier bands, signal strength, active SIM and mobile-data plan before installation.
Does the camera support active deterrence and two-way audio?
Yes. The camera includes a built-in microphone and speaker for two-way talk through the compatible mobile application. Supported alarm events can also activate warm-light and audible warnings, and Dahua states that several built-in warning voices and imported custom audio are supported. Performance depends on mobile-data latency, speaker volume, mounting location and surrounding noise, and audio recording or talk functions should comply with applicable privacy requirements.
What area does the 3.6mm lens cover and how far does the illumination reach?
The fixed 3.6mm lens provides a 78.4° horizontal, 42.4° vertical and 92.4° diagonal field of view. Dahua lists DORI distances of 78m detect, 31.2m observe, 15.6m recognise and 7.8m identify. The Smart Dual Light system provides infrared illumination up to 30m and warm light up to 20m. Actual results vary with mounting height, target size, weather and available ambient light.
How should the solar camera be positioned for reliable detection and charging?
Dahua recommends mounting the camera about 2m to 3m above the ground and setting the horizontal PIR angle between 10° and 30°. The solar panel should receive strong year-round sunlight with minimal shading and suitable 4G signal. In the Southern Hemisphere, the panel should face true north, with its tilt adjusted broadly to local latitude. Trees, roof lines, dust and seasonal shade should be assessed before installation.
What should I confirm before ordering this 4G solar camera?
Confirm the regional 4G variant, local carrier bands, SIM and data plan, mobile signal, daily sunlight, mounting orientation, event frequency, required battery autonomy and microSD retention. Also check whether the 78.4° view and 15fps maximum frame rate suit the evidence area. Security Wholesalers can review the intended site conditions and operating mode to identify likely power, coverage or connectivity limitations before deployment.
