Rosel holding has developed the PRES-VM anti-UAV device that combines passive detection and electronic countermeasure systems. It is designed to protect civilian vehicles in potentially hazardous zones. A compact device is easily mounted on a car roof and operated from mobile devices. 

Passive detection determines radio signals in a wide frequency range in a radius of 360°. It also provides radar reconnaissance deception. 

A built-in video signal interception function allows the device to recognize the type of drone (FPV, DJI and Autel) and detect a hazard with high accuracy. Such verification system prevents response to decoy targets and provides equally effective operation of the PRES-VM in a town, village, field or forest. The built-in countermeasure system suppresses frequencies, which are most commonly used by drone operators, thus making UAV operation impossible. 

The product operates without failures in any weather and at temperatures from −40 °C to +40 °C. The device is quite compact, weighs only 15 kg and, therefore, can be easily secured to a car roof in a conventional rooftop cargo carrier. The device is powered by dedicated batteries as well as from a high-power automotive alternator.
