A MICRO spy bug transmitter for room monitoring for long distance jobs. It uses 2 cell batteries (CR2430 ). Broadcasting on the UHF band for achieving high performance and privacy. These audio spy bugging devices are for the serious customer who needs the best in audio surveillance. All of these bugs can be supplied in 433 or 418 MHz frequencies. Each bug has a specific frequency or channel number, so using one of our multi channel receivers you could monitor audio transmitted from multiple listening devices from a remote location. The transmitters are very easy to use, simply insert the batteries and the unit is working, transmitting all audio information within the room to the remote receiver.
The audio clarity is crystal clear and you do not need to worry about drifting signal as with low cost equipment. Once the receiver locks onto the transmitted audio signal it will stay permanently.
The range is approx. 300m on crowded urban areas and up to 800m (line of sight). Maximal output 14Bm. Super sensitive microphone. Requires an UHF receiver (we sell 2 UHF receivers) or an UHF scanner. One of the best spying and bugging on the market!
This transmitter is designed especially for difficult places, crowded or located on lower floors. The HP36 transmits powerful, clear sound. The transmitter is designed and tested in our specialized laboratory and tested as well "on field" by high skilled engineers for maximal distance.
