DC520 Bi-directional

 People Counter 

DC520 is a people counter which is designed for managing crowd control in places like conference rooms, hotels, parks, factories, etc.

With millimeter wave radar technology, it can accurately detect and count the number of people entering and exiting. 

When people number exceeds preset threshold, DC520 automatically uploads alarm information to specified cloud server through the built-in wireless module. Users can view and analyze data remotely.
