GSM listening device module (EXCELLENT)

The listening device module EXCELLENT+ is the result of our long-term development and solves all the problems that GSM listening devices previously struggled with. Through a special adjustment of the microphones, we achieved an especially clear listening experience even at a distance of more than 5 meters. The GSM module is prepared for connecting various types of batteries, allowing it to operate for more than 90 days without requiring a recharge. The GSM module EXCELLENT is particularly aimed at demanding users who want to use the device for long-term monitoring of a room with the highest sound quality. You only need to insert a SIM card from any operator that has 2G/3G network coverage in your area (frequencies 850 MHz, 900 MHz, 1800 MHz, 1900 MHz) into the device, call it, and you can listen to what is happening in the area. It is very important that you have good GSM signal coverage of the 2G/3G network at the location where you want to use the device. A spare battery can also be easily connected to the module. At the moment when the listening device is discharged, recharging is not required, but it is sufficient to replace the battery in a few seconds, thus ensuring the operation of the listening device for up to another 200 days.
