The Hikvision DS-2DE5425IWG-4G is a professional PTZ security camera designed for remote surveillance where traditional power and network infrastructure are unavailable. It operates via a solar power system and maintains connectivity through a 4G network, making it a reliable choice for monitoring isolated perimeters or large outdoor areas. The camera captures detailed images with a 4-megapixel resolution and utilizes a 4.8-120mm varifocal lens that provides a 25x optical zoom, allowing you to see distant objects clearly without losing image quality. To manage energy efficiently, the device features a performance mode and a low power mode, which reduces consumption to 3 W, while sleep mode drops it further to 0.3 W. For storage, it includes built-in eMMC memory of up to 256 GB, ensuring footage is saved locally. The hardware is built to withstand harsh environments with an IP66 weather-resistant rating and integrated heating glass that prevents fogging on the lens, ensuring a clear view even in humid or cold conditions. Nighttime monitoring is handled by an infrared system with a range of up to 150 m, while the sensor maintains color images down to 0.05 Lux. For easier setup, the camera supports a Wi-Fi hotspot on Channel 11 for short-distance debugging. It also allows for 12 V 1 A reverse power input, providing flexibility in how the system is maintained in the field.
