This listening device is the smallest and lightest in our room transmitter range. It is small enough to be concealed in any pocket or bag, as well as easily hidden in any home or office. It can easily be hidden under a desk or piece of furniture using a tiny amount of Blue Tack (Or even chewing gum).
The listening device's internal microphone is super-sensitive and can pick up even the faintest sounds within a 10m radius. The device then transmits those sounds, which can be received on a compatible UHF receiver (such as our 12CHRX) within a line of sight range of up to 800 metres.
The UHF crystal controlled circuitry ensures that the frequency of the signal is ‘locked' and will not drift, giving guaranteed performance in the most demanding audio surveillance situations. The listening device is powered a single 3V lithium battery that will provide approximately 40 hours of transmission.
Please note, due to the listening device operating on UHF frequencies it is not legal for sale or use within the EU and can only be shipped to non-EU addresses.
