Questions to ask every provider
- Who operates the monitoring centre, and is it independently certified?
- How are alarms verified before escalation?
- Who is contacted first: you, a keyholder, police, fire service or a private responder?
- Which response services cost extra or depend on location?
- What happens during internet, mobile-network or power failure?
- What is the minimum contract, cancellation process and equipment ownership position?
Security licensing, patrol availability and police alarm procedures vary by state or territory. Ask who physically responds in your postcode and whether that service has an additional charge.

Alarm verification before escalation
Ask the provider exactly how an alarm is verified before contacts, guards or emergency services are called. Confirm whether it uses multiple sensor signals, audio/video verification, callback procedures or another approved process; what happens when nobody answers; and how false activations affect the account. Monitoring does not guarantee dispatch, police attendance or a particular response time.
