Auto Tracking Auto Track Advanced IVS PTZ tracking is an innovative feature that transforms manually controlled PTZ cameras into automated tracking systems that keep an moving object in focus and centered in the frame. It follows the object where stationary cameras would lose the object once out of the fixed cameras field of view.
Smart Tracking Smart Tracking Premium IVS Smart tracking is the linked monitoring between the PTZ camera and other devices, such as Radar and Thermal camera. When the camera detects the target, it sends signals to the PTZ camera for tracking.
Thermal Camera IVS Thermal Camera IVS Premium IVS In some special environment, the Thermal camera can realize some IVS function that the normal cameral can’t, such as the object missing/object abandoned/intrusion/tripwire

People Counting People Counting Advanced IVS Provides people counting, region people counting, linkage alarm, and statement generation functions.
Perimeter Perimeter Analytics+ Dahua Perimeter Protection technology can recognize human and vehicle accurately. In restricted area (such as pedestrian area and vehicle area), the false alarms of intelligent detection based on target type (such as tripwire, intrusion) are largely reduced.
Heat-map Heatmap Advanced IVS It is used to detect the level of motion of moving objects in a certain time. Supports the statistics of the cumulative population density within the set time range, and displays in space with different colors.
LPC & LPR Traffic Enforcement Premium IVS Analysis the traffic situation according to the traffic flow
