When permanently installed in a building, sweeps can be initiated remotely from anywhere in the world using TCP/IP connectivity. The MS300 can be configured to protect premises 24 hours a day, sending e-mail reports of any new signals detected. The software can also be configured to send a spectrum analyser snapshot of new signals, to allow operators to analyse signals remotely even when they appear only briefly.
Automatically sweeping through the frequency range 10kHz to 15GHz, the MS300 has an integral Microwave Down Converter, to give the widest range available. It provides what is described as an ultra-sensitive sweep across the covered frequency band, detecting analogue listening devices operating in the LF, HF, VHF and UHF spectra. It is said to be particularly effective against frequency-hopping and spread spectrum devices, an integral video demodulator aids the detection of video transmitters, and an optional GSM mobile phone detector detects devices operating on the 800, 900, 1800 and 1900MHz European and US frequencies.
