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.

Plans for kits are written and detailed for the beginner. The indicated operating ranges suggest the use of a properly tuned antenna and high quality communication receiver.  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.

Video Camera Detector
Feel like someone's watching you?
The Camera Detector is so small you can take it anywhere. When a wireless camera is detected, an LED light flickers and an audible alarm sounds. Advanced circuitry reduces false alarms from background interference. A sensitive tuner allows you to automatically scan variable distances and channels. The unit detects frequencies from 50MHz to 3GHz.
  • Dimensions: 3-1/4" x 1-1/4" x 3/4"
  • Weight: 1 oz
  • Batteries: 2 x CR2032 (included)
  • Coverage: 50 Mhz - 3 Ghz

Super sensitive detector "sniffs out" legal and illegal listening and surveillance devices. Alerts you to wireless video transmitters, bugs and other sources of potentially bothersome radio interference and emissions. Detects any RF source from 1 megahertz to 5 gigahertz. Unit has a built in vibrator for covert alerting in sensitive areas, sensitivity adjustment, LED indicators, speaker, and includes headsets. This detector compares with units costing several times more and will match anything currently on the market. Small 2 x 3-1/2 x 5/8" uses 2 AAA batteries (not included).

Frequency Detector with Strength Meter
Uses the latest micro-processor technology for the most accurate hand-held detection of radio frequency wireless transmissions. It must be within one foot of a wireless device for the frequency to be accurately measured. (When searching your home or office for bugs, be sure to search everywhere. Bugs come in many shapes and sizes, some being smaller than a penny.) LCD screen displays frequency being detected. Full detection range from 1 MHz to 3 GHz. This device cannot locate a bug, but the built-in signal strength meter and sensitivity control can be used to gauge how close you are to a bug.
