Critical Infrastructure Monitoring | Duons Australia



Duons offers a range of solutions and full service support for business looking to integrate automated monitoring of their critical infrastructure into their everyday operations. As exclusive Australasian distributor of ServersCheck monitoring systems, we provide a turnkey product backed up by our in-house support and technical expertise to assist you with the customisation and adaptation of the technology where necessary. We also have access to a range of other technologies and the R&D capacity to tailor an environmental monitoring for a broad range of situations across all industries.


Modular, scalable and affordable solution for monitoring critical facilities

ServersCheck’s ‘building-block’ approach and extensive range and variety of components makes it the ideal option for customising a monitoring solution to specific requirements, whether basic temperature monitoring for a small business’s server room, right up to tracking a wide range of environmental, power and security parameters in a complex industrial setting.

A modular and scalable approach means you only pay for what you need, and can be confident that if requirements change, the system can easily be adapted and expanded to suit your evolving needs. Complimentary cloud-based monitoring software, smartphone apps and firmware upgrades add extra value for money.

The SensorGateway – the foundation of your networked monitoring solution

The base unit of the monitoring, providing a link between the physical environment to be monitored and the user’s digital monitoring and control interface. Complete with its own in-built temperature monitor, PoE and ports for 2 x additional sensors / 1 x expansion hub.

The Sensorhub – expanding monitoring and control potentials


Expansion modules like the Sensorhub open up powerful potentials for monitoring and control, offering addition ports for ServersCheck sensors, as well as dry contact inputs for legacy sensors (smoke alarms, door contact etc). Added to that, open collector switches and relay outputs mean that the ecosystem can be configured to automate intelligent responses to breaches of certain conditions, for example having a back-up air-conditioning activate if the temperature gets too high.

Alerts and controls are all able to be coordinated and monitored remotely from your workstation, or even out and about via your smartphone or tablet. The end result is improved efficiency, security and peace-of-mind for your organisation.
