Audio Surveillance Equipment

Our listening devices can be used for audio surveillance in a home, office or vehicle and will pick  up whispers from 30 feet. These ultra miniature transmitters are available concealed into a range of everyday items from a ballpoint pen to a pocket calculator. All products are manufactured using premium quality components for ultimate reliability and performance to give distortion free, exceptional quality audio. Our GSM devices use the mobile phone network to transmit audio and hence have no range limitations. We also manufacture a dedicated  UHF receiver for use in conjunction with our UHF audio surveillance and telephone surveillance transmitters. Contact us to find out more about any of our products.
