A complete stand-alone remote monitoring system.

Keeping a constant eye on remotely located assets requires more than an SMS, email or phone call. It requires a customisable blend of communication methods to a range of users to ensure mission-critical information is delivered and handled efficiently. Reliable remote monitoring from ControlFreq is tailored to suit your application.  

Customisable remote monitoring with a web-browser UI.

ControlFreq customisable web-based software is what separates our remote monitoring from the competition. Our WebAlarm onboarding team work with you to deliver the data you need to see, where you need it and all in real time.

Alarm & fault events delivered over modern communication paths!

Not all remote monitoring applications are the same. Some require just a simple SMS or phone call notification while others command more sophisticated, rule-based & event logged reporting systems delivered over multiple communication paths for mission-critical notifications in realtime.

Smart remote management for people with no time to waste.

ControlFreq apps are designed for system adminstrators to take full control of system and user management in-house for more efficient operations while offering 'self-manage' installers the ability to generate ongoing service income.

Self-contained 'stand alone' electronics for easy integration.

ControlFreq hardware can be easily integrated into 3rd party systems using industry-standard mounting systems such as DIN rail. If your application requires a bit of customisable flexibility, that's where ControlFreq outshines the competition. It's what we do best.

Product Information

Advanced Remote Monitoring for any Application

Highly configurable & universally adaptable remote monitoring for virtually any application...

The PRO+4G is a highly configurable, advanced professional 4G GSM auto-dialler designed to remotely monitor virtually any remote fault or alarm condition.

The alarm trigger can be an alarm panel of any kind, a volt-free relay contact N/O or N/C, positive or negative voltage or directly from any type of sensor. The PRO+4G is truly universal for any application.

With the optional battery back-up fitted the PRO+4G offers instant remote mains-fail monitoring. It's a valuable solution if used for that purpose alone. See the mains fail version here.

The PRO+4G sends custom SMS and/or voice calls up to 10 user phones with customisable SMS and voice message.

Optional services allow for customised alarm delivery including email and WebAlarm® web-based ARC monitoring alternative.

WebAlarm® is a new way to remotely monitor an unlimited amount of locations with web interface, email, SMS & phone call notifications to dedicated receipients per location.

Very powerful yet simple remote monitoring.
