The Mriya GSM Transmitter in functional 5V/2A Travel Adapter is a fully covert black-box designed GSM bug that has an unlimited power supply.
This GPS audio bug has been designed so it can not be detected even if inspected closely. The screws used to hide the panel with SIM card, LED light, and microphone have been specially made, and you need the provided screwdriver to be able to remove it.
You can set up the device to let you know if audio is detected in a room, or if someone is touching/moving it. Security is the main theme of this device, so only you will be able to call in and hear the audio in the room. This is made sure by the administrator number. Everyone else will just get a busy signal, and will not be able to reach the device. You can even pinpoint the location of the device via the LBS station.
The HQ analog microphone for GSM communication will provide clear sound on the whole surveilled parameter. You will be able to hear the conversation from the back of the room. This is important as some devices have clear sound only if the conversation takes place in close proximity.
The Mriya GSM is a low-maintenance device as it provides unlimited listening in time when connected to a power socket. In case of a power shortage, it will operate for 2 more hours autonomously, and with the Sleep mode, you can have it 24h in stand-by mode.
