4-MP 1/2.9" CMOS image sensor with high definition and low luminance. supports (2560 × 1440)@25/30 fps and has a maximum output of 4 MP (2688 × 1520)@20 times. Ultra-low bit rate, high compression rate, H.265 codec. The maximum illumination distance is 50 meters, and there is built-in warm light. ROI, SMART H.264+/H.265+, adaptable coding, suitable for a range of storage and bandwidth conditions. Digital watermarking, rotation mode, WDR, 3D NR, HLC, and BLC are all useful for different monitoring scenarios. Intrusion and tripwire are two examples of intelligent monitoring that help with accurate vehicle and human detection and classification. Motion detection, video tampering, audio detection, no SD card, full SD card, SD card error, network disconnect, IP conflict, unauthorized access, and voltage detection are examples of abnormality detection. Audio: 1 in, 1 out; alarm: 2 in, 2 out; maximum support of 256 G
