The warning that ends most incidents on the spot.
Through speakers installed on your property, Sentrix operators speak directly to intruders the moment they are verified, describing what they see and warning that police are being dispatched. Knowing they are being watched and named, the overwhelming majority of intruders abandon the attempt immediately.
Deterrence before dispatch
Audio intervention sits between detection and police dispatch, and often makes dispatch unnecessary. It is faster than any response unit and stops the incident at the earliest possible moment. Combined with live monitoring, it turns your cameras from silent witnesses into an active line of defence.
Verify
The operator confirms a genuine intrusion before speaking.
Challenge
A live, specific warning is delivered through on-site speakers.
Resolve
Most intruders leave immediately, and if not, we escalate at once.
What is included
Included with live monitoring and virtual guard plans: real-time two-way audio, a verified challenge-and-warn protocol, escalation if the warning is ignored, and full event logging. Requires compatible on-site audio hardware, and we will advise on setup.

How a voice-down warning plays out.
From the first sign of an intruder to the moment they leave, here is the sequence.
01
Detect
Detection flags an intruder on the live feed and alerts the operator.
02
Verify
The operator confirms it is a real person and a genuine intrusion.
03
Voice-Down Warning
A live, specific warning is spoken through on-site speakers, naming what they are doing.
04
Resolve or Escalate
Most leave at once. If not, police and your contacts are alerted immediately.
Where audio intervention works hardest
Stop them at the fence line
A voice warning the moment someone climbs a fence ends most intrusions before they reach anything of value.
- Perimeter fencing
- Loading bays
- Open storage
Warn before they get in
A live challenge at a shopfront or back door turns away most after-hours intruders without a call-out.
- Shopfront and entrances
- Back and side doors
- Stockrooms
Deter equipment theft
Open sites with valuable machinery benefit hugely from a voice that makes clear someone is watching live.
- Equipment zones
- Material storage
- Site gates

FAQs
Audio intervention, answered.
What exactly is audio intervention?
It is a live two-way audio capability. When an operator verifies an intruder, they speak directly through on-site speakers, warning the person off. Most leave immediately.
Is it a recording or a real person?
A real, live operator. The voice describes what the intruder is doing in the moment, which is far more effective than any recorded message or siren.
Do I need special speakers?
Yes, compatible on-site audio hardware is required for two-way voice. We advise on the right setup during onboarding.
Is audio intervention a separate service?
It is a capability included with live monitoring and virtual guard plans, and it can be paired with remote monitoring. It works alongside, not instead of, your monitoring service.
What happens if the warning is ignored?
The operator escalates immediately, alerting police, rescue, and your contacts with verified, live detail of what is happening.
