The Dahua IPC-HFW2441DG-4G-SP-B-MAX is a versatile 4 MP security camera designed for remote locations where traditional wiring is unavailable. It captures video at a resolution of 2560 × 1440 and uses H.265 compression to keep file sizes manageable. Connectivity is handled by an integrated 4G module, while the system is powered by a 64Wh lithium iron phosphate battery, specifically a wide-temperature variant that ensures reliability in challenging climates. To maintain a constant charge, the camera features a solar panel with adjustable angles, though you can also use a Type-C port for temporary power or a 12 VDC input for an external panel. Security is enhanced by a built-in PIR sensor and Smart Motion Detection, which trigger a combined sound and light alarm to deter intruders. For nighttime visibility, the device employs dual lighting, switching between infrared LEDs that reach 30 meters and warm lights that cover up to 20 meters. You can communicate with people on-site using the integrated microphone and speaker for two-way talk, and store footage locally on a Micro SD card with capacities up to 512 GB. Built to withstand the elements, the housing is IP67 rated for dust and water resistance. The AOV (Always On Video) mode allows for continuous 24/7 surveillance while optimizing power consumption, making it a practical choice for monitoring remote perimeters, construction sites, or rural properties where you need a dependable, standalone security solution.
