The Hikvision DS-2XS6A25G0-I/CH20S40 is a solar-powered 4G network camera kit designed for remote surveillance where traditional power and internet cables are unavailable. It captures video at a 2 MP resolution with a 1/2.8" Progressive Scan CMOS sensor, utilizing 120 dB True WDR to maintain clear images even in challenging lighting conditions. Connectivity is handled via a Micro SIM card supporting various 4G wireless transmissions, while a built-in slot allows for local storage on microSD cards up to 256 GB. Energy is provided by a 40 W photovoltaic panel and a 20 Ah rechargeable lithium battery, which can keep the system running for up to 7 days during cloudy or rainy weather. The battery system includes protections against extreme temperatures and low-battery sleep modes to ensure stability. For night vision, the camera uses IR illumination that reaches up to 30 meters, and the entire unit is housed in an IP67-rated enclosure to withstand harsh outdoor environments. Depending on your needs, the kit is available with 2.8 mm, 4 mm, or 8 mm lenses to adjust the field of view from a wide 128° angle down to a more focused 47°. Weighing approximately 10.16 kg and measuring 760 × 732.6 × 586.9 mm, this setup is well-suited for monitoring isolated sites, agricultural land, or construction zones where you need reliable, autonomous security.
