What does Grade A1 Monitoring Centre mean?

A Grade A1 Monitoring Centre is the highest classification for a Monitoring Centre according to the Australian/New Zealand Standard.

The standard sets out the requirements for grading the construction of monitoring centres and the equipment and staff used to monitor security systems. The grading is determined based on two separate parameters: building services and construction, which are graded on a scale from A to C, with A being the most resistant to attack, and operation, equipment, and staff, which are graded on a scale from 1 to 3, with 1 having the highest performance.
