ZK-Teco ES-854N21C-S5-MI Dome 2MP 30M 3.6 MM PoE IP Camera has the features: Lite Series is a super cost-efficient solution that is powered by cutting-edge technology for crystal clear video monitoring with an embedded face detection algorithm. The P2P cloud function is built-in for every device, allowing more convenient and flexible remote real-time viewing and monitoring. Functions H.265 H.265 technology is an evolutionary optimization of traditional H.264; it includes a series of encoding strategies such as dynamic ROI, smart 2D&3D noise reduction, and so on, for delivering high-quality videos, and significantly saving up to 70% bandwidth and storage. Protection With the precise mechanical and rugged metal casing design, IP cameras of the Lite series rated IP67 could stand against water and dust for a long time. With 10% of input voltage tolerance, the cameras could work safely under extreme or unstable power conditions. With a working temperature range from -20°C to 55°C, the cameras could adapt to a variety of harsh outdoor environments
