Why don't we sell online?

ControlFreq has been selling online since 2009.  We're now actively seeking reseller partners.

Over the past two years we have developed the 'Alpha Control Ecosystem' [ACE]. We have made the decision to concentrate our focus on the core technology, as a manufacturer & cloud service provider, while hardware sales are channelled through online partners.

New and existing customers can  purchase directly from us, offline, until suitable Reseller channels are in place, at which time we will direct all online sales through partners. This is a transition we have decided to make to focus on 'Made in Britain' manufacturing &  the connected services to compliment our products.

If you would like to become a reseller please connect with us to arrange an intro call and demo meeting.

All technical support and paid services like contract SIM cards, managed services & cloud management subscriptions will be provided by ControlFreq directly.

When an end purchaser activates a ControlFreq product, these services become available. 

Product Detail

SOLO4-4G | 4G GSM intercom - 4 way

Robust 4 way simple retrofit entry system for up to 4 properties...

The SOLO4-4G is a highly configurable GSM intercom, for 3 or 4 separate properties, with remote online configuration & user management.

The unit is a robust design with brushed stainless steel fascia and powdercoated stainless steel surface backbox. The IP68 antenna is pre-fitted into the top of the unit eliminating the need to install an external antenna.

The stainless steel keys on the unit are LED backlit with an IP68 silicone membrane behind for maximum protection against the ingress of water and dust.

The unit operates on 2G/3G and 4G with a 4G (vo-LTE ready) module onboard for future-proof mobile connectivity.

Door release can be activated from the user's phone keypad during a call and also at any other time by Caller-ID 'free-call', SMS, App, Web-browser or via times preset using the inbuilt 24/7/365 time-clocks (2).

The audio quality is nothing short of perfect. Configuration and user management is done via web-browser or smartphone app, primarily designed for installers.

ControlFreq apps are intended for an installer to offer a managed service to end-clients, thereby generating recurring service revenue, while providing the best possible managed service to the client – supported by ControlFreq, 7-days, by phone.
