The MTX range of transmitters are powered by the mains supply to which they are connected. As long as there is a power supply the transmitters will operate indefinitely, without the need to change batteries. This makes them ideal for long term monitoring. All the products contain a hidden microphone and transmitter circuit for crystal clear audio monitoring. The devices are concealed in every day electrical adaptors and sockets so, even on close inspection, there is nothing to give away their hidden circuitry. These products can be used as direct replacements for existing adaptors or sockets and are available with UK, European and US plug types. Other versions can also be supplied on request.
