Listening surveillance devices - Parabolic Sound Collecting Dish
As an example of a sound collecting dish, the unit features an 8X optical
viewer with coated optics and fold down rubber eyecup. A sensitive sound detection system that is capable of
detecting a human conversations over 300 feet away. Sounds from listening surveillance can also be recorded up to 12 seconds on the digital chip
for playback or transfer to tape. For optimum sound quality, unwanted background noise can be tuned out with the built
in frequency reducer. Included with this listening surveillance device should be a pair of comfortable, padded full size headphones.

Electronic background noise filter.
May requires a 9 Volt Battery (not normally included).
Indicative price $69.00
Listening surveillance devices - sound microphone
Developed for picking up sounds from a distance of up to 50 yards. Super directive use. Can pick up objective sound
clearly, even in noisy environments. A 3.5 mm plug output jack can be connected to most tape recorders. Can be
handheld, stand mounted, or mounted on camcorder, video, or movie equipment. Just aim at target and listen, very simple
and effective. Approximately 16 inches long and 7-1/2 inches high when mounted on tri-pod.
Electret condenser microphone for listening surveillance.
Sensitivity -60dB (1kHz0dB=1V/ubar).
Output impedance 600ohm(1kHz).
Frequency range 50Hz-10kHz.
Includes amplifier and head set.

VHF - High performance Xmitter and receiver VHF
This high performance listening surveillance wireless microphone is approximately the size of a pager. It will transmit sounds for a distance of up
to 500 feet and can be received with the included receiver or a scanner. It normally includes a high quality
omni-directional
electret condenser microphone for the greatest sensitivity. Housed in a durable plastic case with snap-on belt clip
and a 3 position power switch with standby for muting the audio. Powered by a 9 volt battery (not normally included). FCC
Approved.
Switch selectable frequency (2 available).
Includes everything shown in picture.
Dimensions: 2.5 " W x 4" H x .75 D
Includes belt clips.
Requires 2 - 9 volt batteries (not included).
Indicative price $189.00
Listening surveillance devices - FM Transmitters
This type of FM Transmitter can transmit over 900 feet in the open depending on aerial used. The tank oscillator coil
is built into the circuit board, and has been tinkered with to give the best distance and stability for it's size.
The battery supply rails have been well tied together with respect to radio frequencies. The tracks are also thicker
making the fm listening surveillance transmitter circuit a single solid block eliminating RF currents in different parts of the circuit.
This also means the battery no longer has RF on it which makes the whole unit a lot more frequency stable. Can be
tuned anywhere in FM band.
Specifications:
L: 1-3/4" W: 7/8" H: 1/2"
Requires 9 Volt Battery
Transmission frequency is user selectable.
Transmitter can be listened to on any FM radio.
Indicative price $49.00
