Smart spies can build their own bugs; ones which average TSCM detection equipment can't see. One example of this are bugs which use off-the-shelf Bluetooth technology, like Bluegiga. Short range, but very effective.
Another example is second generation Zigbee which can transmit audio a much greater distance.
Both signals are digital. Both blend their transmissions into the sea of legitimate WiFi signals which surround us.
The cost for building these advanced bugging devices is less than $100. per bug.
Discovery requires the most advanced TSCM instrumentation... like what you will find only here.
