Shown are six electronic bugging kits that are offered with instructions on how to build these effective covert miniature spying transmitters for voice and telephones. Unfortunately products of this nature are not legal when used to listen without one party being aware. So if you are going under cover check all applicable state and federal surveillance laws to ensure compliance. 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 is a video camera disguised as a working wristwatch with built in color camera with audio and recorder, a real truly powerful covert device.

Laser window bounce listening systems are available complete and ready to use with the latest technology cost upwards of $30,000 and are not available to the average person but only to law enforcement. These systems shown here will not offer the same performance obviously as a $30-$40,000 system however properly assembled they can be a very useful tool for many applications. Not only are they useful for covertly detecting voice communications behind a closed window but they can also be used for listening to high-voltage insulators on transmission lines, cooling pipes used in nuclear reactors, and many other mechanical things that are difficult and dangerous to get to.

One of the approaches offered here is a simplified low cost system. It can be used to demonstrate the concept and is suitable for an advanced science project. It can also be used as a long range optical voice communication link

Remarkable concept where you listen to sounds picked up from a reflecting surface illuminated by a laser. These light reflections, or scatter, are reproduced back to the original sound by our special optical receiver.

Assembled laser and receiver modules may be placed on video tripods and temporarily aligned for limited performance demonstration systems. They may also be enclosed as shown in the instructions for use as a field worthy device with a potential range of up to 500 feet. May also be used as a long range laser voice communicator with a range usable to 10 miles line of sight with the proper optics. Low cost audio surveillance science project or useful device for listening to power line faults, over pressured pipes, etc.

The plans for this device show 3 systems ranging from a low cost science project to a long range infra red surveillance system, and also include the LVC1 long range optical voice communication system.

Further LWB9 Operational Information

A more basic, but fully functional, system for proof of concept, science fairs, and use over shorter ranges. Options for upgrading the optics to focus the outgoing beam, and gather and refocus the incoming signal, would allow this system to be used over longer ranges. Includes laser diode module, LLR30 optical receiver, and full instructions. You supply the individual video tripods or other mounting platform. Ready for set up and use!

Detects ultra low level voice modulated light waves. Use for laser window bounce with our invisible IR laser #CWL series or for long range optical communication. Built in voice filter with many amenities. 9 volt battery operation with cushioned headsets easily mounts to video tripod. Features low noise G_aA_sFET preamplifier. Includes external light bias control, EXT10 extender and condensing lens, HS20 cushioned headsets with individual volume controls and LWB9 plans showing how to make 3 laser window bounce systems.

Cylindrical Enclosure Easily Retrofits To Tripod Includes Headsets 9 Volt Battery Operation Adjustable Gain Control Sensitivity Adjustment

Similar in operation to our more expensive LLR40 series but without optics, headsets and low noise front end.
