Infinova VT311-A2 series HD 2MP Intelligent Star Light WDR IR IP camera applies 1/2.8 CMOS sensor with built-in 2.8~12mm or 7~22mm motorized vari-focal lens. With built-in IR lights, the IR illumination distance covers up to 50m and the power can be auto-adjusted according to ambient lighting conditions, which can vastly reduce power consumption and extend its service life.

WithH.265/H.264/M-JPEG video compression formats, the camera outputs high-definition images with resolution up to 1080P@30fps, which can provide marvelous definition, color restoration and accurate details.

With self-developed deep learning algorithms, the camera is endowed with vivid smart functions such as video anomaly detection, face detection, face tracking and face capture, counting, density detection, and behavior analysis, catering for various high-end requests. The camera is widely used in communication, governments, schools, factories, garages, warehouses and other occasions with low light condition but requesting high-resolution image quality.
