Model: AES GSM-4AB
These AES GSM intercom systems are a great solution for home & business communication, compatible with all types of automated gates, garage and automated doors. When a visitor presses the call button the call comes straight to the phones of your choice using the GSM network (sim not provided), once you have spoken to the caller you can operate your gates or door with the touch of a button. The caller doesn't know if you are home or not. Another handy feature is the built in Caller ID switching which allows authorised numbers (authorised by you) to call the system and open the gates or door.
