This is a micro-spy bug listening device for room surveillance, covert bugging, and spying purposes over a longer distance. It operates in the UHF band for maximum performance and privacy.
This gadget is available in 433 or 418 MHz frequencies.

The transmitters are really simple to operate! Simply attach the batteries, and the spying bug activates, sending all audio information and conversation in the room to a matching UHF receiver (not included).
The audio is very clear and consistent. When the receiver is set to the same frequency as the transmitter, the transmitted audio signal remains constant.
In densely populated regions, the range is around 150m and can extend up to 600m (line of sight).
The audio bug employs a highly sensitive microphone.
This gadget was created and tested in our sophisticated laboratory for maximum distance, as well as in real-world circumstances by our highly trained team.

Compatible receivers:

or any receiver within 400-450 MHz band and 2.5 kHz steps.
