This Special Vehicle Microphone mounted on top of a vehicle is e.g. used on police cars. Its flat design uses the reflections from the underground like a sound pick-up, on request reduces street/traffic noise and offers clear recording within a circumference of 15m. Watertight thanks to a special technology, however, the PKI 2520 Special Vehicle Microphone is very sensitive.
