GSM Audio Listening

Audio surveillance is fast evolving.  Unlike 'off the shelf' products we pride ourselves by offering a wide range of customised audio equipment to best suit your requirements.  We offer two (2) types of audio surveillance - GSM and UHF technology.

GSM technology uses a standard network GSM SIM card (800 - 1900MHz) - simply by calling the SIM card from either your land-line or mobile phone, you will hear the surrounding audio thus allowing you to monitor and safeguard your home / office environment.

UHF Technology is more advanced and more restricted to use.  UHF (ultra high frequency) is a crystal controlled frequency so the audio quality is extremely good and is difficult to interfere by third parties.  UHF operates on a transmitting frequency between 300MHz - 3000MHz, also known as the decimetre band or decimetre wave as the wavelengths range from one to ten decimetres (10cm to 1m).

Please Note:  We will not sell UHF equipment within the EU due to strict regulations however, we may deliver UHF equipment to a country outside the EU.  Please contact us to discuss your requirements.
