GSMB2G - GSM receiver

GSMB2G is a GSM receiver capable of operating a relay. It is a very simple appliance and can be used to control access to doors, gates, as well as remote electrical or electronic devices. The device can be used in any circumstance where you need to turn on or off any equipment, by a free (phone call) or by SMS from a mobile phone.
Just dial from a phone number previously authorized by the administrator the phone number of the SIM card inside the GSM device and the barrier, gate, garage or any connected port will open, or the electrical equipment to which the GSM receiver is connected will be switched on or off. There are no call costs, as the GSMB2G receiver rejects any call from authorized phone numbers and then it will switch the relay.
In addition, a specific user can be authorized only for a limited time, and once the time has expired, it will be impossible to carry out operations on GSMB2G receiver.
