A mini spy bug for room monitoring NANO SIZE. Professional audio bug. It uses one battery (Alkaline, 9V). Broadcasting on the UHF band for achieving high performance and privacy. The range is approx. 200m on built area and up to 600m (line of sight). Maximal drawn current: 30mA. Maximal output 12Bm. Super sensitive external, gild, brand microphone. For privacy and distance, it requires an UHF receiver (we sell 3 UHF receivers) or an UHF scanner. It can be concealed in a hidden place inside a room, like under the bed, under a desk, inside a toy or other object, after the battery will be inserted in its place. It will capture the sounds in the room and transmit them to a UHF FM transceiver, to a distance of up to 600 meters in open space.
This transmitter is designed especially for difficult places, and can be also used as a body transmitter. The NANO broadcasts powerful, clean audio. The transmitter is designed and tested in our specialized laboratory and tested as well  by high skilled engineers for maximal distance in real conditions.
