ControlFreq made it's first GSM intercom in 2010. We made a PCB to fit inside a Videx 4000 series 1-4 button module. The 4000 series enclosures looked nice and, because they're half plastic, they were cheap.  It served it's purpose at the time as we ventured toward producing our own enclosures. ALPHA-4G is what we created. 

ControlFreq went on to become the go-to access control provider to the on-demand parking industry, creating OEM branded GSM intercom systems, for service-related 'access control management solutions'. ControlFreq GSM intercoms with inbuilt 'API-managed' access control are employed by parking operators to enable (and remotely manage) seamless, secure user access to gated parking, ala 'Airbnb of Parking' – using  ControlFreq 100% mobile technology!

While the competitors' GSM intercoms drift backwards into the shadows, the ALPHA-4G GSM intercom range  demostrates superior technological progress, and outstanding British design & engineering, with a fine attention to detail.

ALPHA-4G GSM intercoms come with a 5-year replacement warranty – standard. Backed by reliable 7-day phone support & powerful online management by app, web or API – We provide and support online tools to simplify access control user management of unlimited number of client locations.

ALPHA-4G has industry-standard access control inbuilt supporting a range of access methods to suit most vehicle access to secure parking facilities. Choose from ANPR, long-range RFID, QR-code reader, PIN keypad, proximity and secure-ID remote keyfobs.
