Based on deep-learning algorithm, VS351-A4 series HD IR IP integrated camera is endowed with vivid smart functions. It’s able to detect 60 faces at the same time, and the detection rate of blurred face, large Angle face, small size face has been greatly improved. It’s able to output images to the backend platform for big data analysis, which effectively reduces loads and costs of smart analysis and handling that the control platform bears. Standard http protocol and SDK are provided to connect to the third-party platform.

The camera has a built-in HD integrated camera module, utilizes large size progressive scanning CMOS sensor and motorized zoom lens. It provides high quality video with the resolution up to 2560x1440@30fps, adopts H.265/H.264/M-JPEG compression formats, outputs six video streams and boasts of excellent resolution and color reproduction ability to ensure richer and more accurate details to be acquired and also guarantee the accuracy of intelligent analysis in a more effective way. The camera adopts large power LED infrared lamps, with infrared wave length of 850nm, covering up to 100m for night view. The IR lamps can turn on or off automatically based on environmental lighting conditions or can be adjusted manually.

VS351-A4 can be widely used in city surveillance, road monitoring, entrance surveillance for subways, shopping mall, supermarket and large venues, crowded places like train stations, airports and other demanding applications.
