Reliable Security Systems / Remarkable Surveillance Systems :: CCTV / Security / Video and Audio Surviellance Equipment :: Audio Surveillance and Microphones
Before there was 'camera' and 'visual' CCTV security surveillance, there
was 'Audio Surveillance' also known as 'Sound Surveillance' and when it comes to
'electronic audio surveillance' or 'electronic sound surveillance'
this is primarily done by way of well placed and well designed 'audio
surveillance microphones' or 'sound surveillance microphones' and their related
'audio surveillance recorders' or 'sound surveillance recorders'. In this
section we have not as yet 'exhaustively' listed all the products availaable on
the market, but we are working on it.
