Using the latest GSM intercom and mobile technology, Control Freq offers reliable 4G wireless intercoms that allow residents or visitors easy access to a domestic home or commercial building safely and securely.
A GSM intercom is a worthy addition to the perimeter security of a residential or commercial building. It communicates with visitors via a landline or mobile phone utilising a SIM card, which once programmed can call one or several chosen numbers in order to grant immediate access for your visitors.
The key benefits of a GSM intercom system include ease of operation, quick, wireless connection and installation, improved security and the ability to operate and manage a property entry from a distance.
Our GSM intercoms come with a 3-year replacement warranty, 7-day phone support and remote online management, plus options include intercoms with or without a PIN code keypad.
If you're done with unreliable hardware, poor technical support, annoying paid services to manage your users or simply 'stuck in the past' technology, it's time to try ControlFreq GSM intercoms.
