37.5 standby days

GLite PRO Large 3600+  is a unique GSM communicator that is equipped with variety of functions, it can serve as a protective device as well as a device for gathering information. The main benefits of this device are clear sound, long battery life and its functions. It is the biggest version of the advanced listening device series GLite, with a mounted battery on the module. The Extended Knowles microphone will help you to monitor places where you can position the microphone with appropriate direction.

We have tried to maintain small proportions but not on behalf of the quality sound, with the combination of Knowles microphones and latest chip-set we believe that this is the highest sound quality we are able to transfer via GSM network. 


  • Password control function, allows you to communicate in a secured matter between you and the unit. That means that you can set a master password for example: 111111 and each time you want to send a command to the unit, you start with that password. This function can also be turned off.
  • Filter for incoming numbers You can select up to 3 numbers to be the master numbers. That means that only 3 people will have access to the device. Anyone else will receive a busy tone.
  • Voice detection Can be also adjusted, as sometimes you might find yourself in a rather noisy environment and you want the sensitivity to be lower. On top of that, you can select "dead time" which is a period of time when the unit will not notify you. 
  • Microphone Preset sensitivity of the microphone can be adjusted to 7 different levels. You will be able to switch between these levels as well as set auto-adjustment value.
  • Light detection Can be used as an alarm if the device is placed in a dark environment, then it will send you an alarm. 
  • Installation The device is plug and play, if you do not need any special function you simply put in the simcard and wait for it to boot and call the device.

*Special note: There is a possibility of customizing GLite PRO chip-set to other batteries and functions, if you have larger order we would be happy to discuss the options.  

Sound quality:

There is a limit to the sound quality transferred over GSM, one of those limits is rooted in the dependency of the GSM networks (includes signal strength). This is a mono GSM device and so we have selected the microphone with the best SNR (signal to noise ratio) in order to maximize the quality at low consumption. We have achieved this by selecting HQ microphones from Knowles

Extended microphone:

Knowles extended microphone version of the GLite PRO + can come in useful when you have time and place to position the microphone. GLite PRO + can be also placed inside an object and you can guide the microphone to the desired location.

The GLite series uses a very simple communication command set, which is easy to master within a matter of minutes. You can also use in-call commands in order to change the settings of the microphone etc. We advise you to read the manual carefully, in order to grasp the full functionality of GLite PRO series devices. Light sensor and in-call commands can come in very handy when used properly.
