The G-2000 works on 3G technology and can handle up-to 999 users. All you need is to insert a valid SIM card and program phone numbers of all users through the PC software or through simple SMS text commands. When an authorised user makes a call to the receiver, it rejects the call and activates a relay. Since the call is rejected, the user is not charged for the call.

The G-2000 works on 3G network therefore the receiver can be activated from anywhere in the country where mobile network is available. For example you can open your gate or switch on your kitchen lights in Sydney from Melbourne by making a call from your mobile phone and without getting charged. It is portable and as simple as making a call.
