Quick Overview

In terms of shop and office covert of hidden listening devices, it really doesn't get much better than this.  Built into this fully functional calculator is a battery operated UHF Transmitter.  UHF is clean and crisp with no distortion or interference from other wireless devices such as WiFi, mobile phones, 2.4Ghz transmitters, microwaves ovens and so on.  Many other listening devices are poor quality both in audio receiving area and quality but many other devices (not UHF) are subject to interference  from virtually anywhereand the more obstacles between the transmitter and reciever, the worse it becomes.

This UHF Calculator is compatible with the receivers listed in the table above. The UZ-10 is the most popular as a recorder can be connected to the receiver output however, if you do not have a suitable recorder, Hidden Camera is able to supply a UHF receiver with recorder already built in.  It's important when ordering the UHF calculator that you nominate your preferred transmitting Channel wich could be A. B or C. 

The receiver has 3 channels also A.B and C and for good reason.  It maybe that you have more than 1 transmitter. You could for arguments sake have 2 or 3 calculators, and each in a different room.  Provided each calculator UHF device  has a different channel setting, the receiver can therefore SELECT which is the 3 devices to listen in live and/or record.  If the 3 devices all shared the same channel the receiver could not function.
