Wireless Audio Listening Device

This is our wireless battery operated long range professional audio listening device or bug. With built in highly sensitive microphone, it can listen into areas of 5 to 50m which is dependant on volume and surrounding background noise. typically if a normal conversation was taking place say 20-30m away and a TV was playing in the back ground then it would be unlikely this listening device would function that well however, if there was no back ground noise and the conversation was indoors (not being whispered) then in all probability the conversation could be over heard. In other words there are many factors that can and will have an affect on eavesdropping as one would find in normal circumstances and this needs to be taken into consideration.
