This is the method implemented in the Protect 1207i which has 6 channels for different frequency ranges and can simultaneously detect 6 different kinds of transmissions at a distance much greater than any common RF detectors. The only way to reliably detect wireless protocols is to use pre-selector chips (saw filters) which attenuate all other signals except the desired ones. Even more powerful signals like GSM 1800 are also hard to detect because of their low sensitivity at higher frequency ranges. This means the common detector cannot detect such weak and non-continuous signals as Bluetooth, Wi-Fi or Wi-Max. The sensitivity of a common RF detector (bug detector) is spread along a wide frequency range, usually 3, or even 6-7 GHz.

A lot of tiny hidden cameras use Wi-Fi for sending the video.And perhaps more importantly the Bluetooth protocol has been specially designed to transmit voices or conversations with high quality at a distance of up to 100 m it can easily be used for bugging. Modern GPS Trackers use the GSM and 3G cellular networks for transmitting the GPS coordinates of a car. For example, a tiny GSM transmitter is accessible at practically any internet spy-shop for only 100-200 USD and can listen to all your conversations in the office or at home. New methods of 'listening and watching' with the help of modern technologies has become widely spread in our times. The Protect 1207i is a new measuring device which can be successfully used by engineers or counter surveillance specialists as a reliable tool for tracing different digital transmissions such as GSM, Wi-Fi, Bluetooth, etc. * Detecting the illegal/prohibited use of mobile phones during negotiations, examinations, in prisons, hospitals, etc Protect 1207i GPS Tracker detector and Wi-Fi/GSM/3G/Bluetooth finder
