The Handheld transmits electromagnetic energy of a certain frequency, which is reflected in all surfaces it hits.
The energy also penetrates all kind of materials except a homogenous (continuous) metal plate. In turn the energy
returns back to the radar. The returned frequency is the same as the transmitted for static objects and for moving
objects the returned frequency is different, higher or lower, this is the Doppler Effect. The detection of the difference
gives the alarm. The alarm may be audible and/or visible.

• Up to 4 x Handheld can be simultaneously monitored and controlled by one Android Smartphone
• In turn up to four Android Smart-phones can upload all information in real time to windows based Command
