GSM intercoms with integrated QR-reader for advanced access user management via booking app. 

QR-codes are one of the most adaptable, flexible, affordable & integrat-able form of access control 'ID token' available. The QR-code can be saved on a user's phone via email confirmation of a booked service ie: parking, event or rental service. The QR code can also be printed on paper and shown to the QR reader for access. QR-codes are dynamically generated during a booking process and sent to the user in a confirmation email or message. QR-codes are ideal for 3rd party on-demand booking services such as pre-book parking. There are many benefits to QR-codes to promote brands while allowing access without a physical access device or PIN code.


GSM intercoms including time/day/date restricted PIN code access – managed online.

ControlFreq apps are designed for system administrators to take full control of user management in-house for more efficient operations while offering the benefit of generating recurring service income.


Handsfree vehicle access control with long-range RFID for GSM intercoms.

All ControlFreq GSM intercoms support long-range RFID for vehicles. This is a very low-tech approach to managing vehicle access for permanent users of a car park. It links the access rights to a particular vehicle allowing permanent tenants to avoid PCN's as in ANPR car parks. Compared to ANPR, where users are required to have their vehicle on a whitelist to avoid parking charge notices (PCN), an adhesive ID token is mounted to authorised vehicle windscreens. The token has a unique ID which is managed using our web-based management platform. Vehicles can still be restricted by time/day/date restriction. All users entry events are logged online for admin use.


Secure-ID remote controls with online management & timezone user access restrictions.

Remote controls you can add, delete, time-day-date restrict, get SMS alertS when they're used, multi-buttons for multi-entry/exits. The ideal add-on for the traditionalists that still want keyfobs but appreciate the security and convenience that comes with web & app-based real time user management..


GSM intercoms with professional branding & custom-design to suit virtually any application.

ControlFreq offer professional branding for GSM intercoms. Suitable for harsh outdoor environments & heavy commercial use, deliver a professional 'on brand' experience from the first customer touch-point in any use case. What the customer will see first is your brand, not ours.
