Bug Detection & Transmitters (FM, VHF, UHF)


Long Range
Wireless Security Devices

Projects that can be used for telephone monitoring in the U.S.A. or CANADA
without caller awareness require our "BEEPER ALERT" device.

This page shows our surveillance and anti-surveillance products.

Shown are devices intended for the nonprofessional to the highly professional user working in law enforcement. As far as we know at this time there are no legal caveats with detection equipment.

The actual transmitting products, unfortunately due to US law and intended for bugging, unfortunately due to US law are not legal to sell as a finished items. However the hobbyist or builder may build up to three of these kits and take it upon himself to register them with the FCC.

Completed Units when properly assembled will tune in the upper frequencies of the standard FM broadcast band. Most high performance standard FM analog receivers work good with these kits

WARNING -  U.S. and Canadian customers must not connect any antenna to the transmitters that exceeds FCC regulations. Allowed radiated output usually equates out to a 50 to 200' range being enhanced by higher quality receiving equipment.

Pocket Sized Bug Detector and RF Sniffer
Detects and locates wireless bugging devices often used by suspicious spouses trying to get the goods for a costly divorce. Business or political rivals may resort to bugging their competition. The list goes on and on.

The following section features six of our covert spying devices.

Shown are six electronic spying kits that are offered at a special discounted price. All include instructions on how to build these effective covert miniature spying transmitters for voice and telephones. Unfortunately products of this nature may not be legal in certain situations when used to listen without one party being aware. So if you are going under cover check out public law 90-352.

The amateur builder will find these kits easy to assemble and very rewarding for the performance obtained.

Included in this section are plans kits and modules on how to make a laser window bounce listening system that is more of an advanced product but very rewarding.

Also available are video camera disguised as other devices with built in color camera with audio and recorder, a real truly powerful covert device.
