How it works

One engine.Every service.

Whether it's a verified alarm, a live watch, a covert stock-room deployment or a control-room failover — the machinery underneath is the same: you set the rules, SARA enforces them, you get the call and the evidence.

You set the rules

Before go-live we build your site's standing orders with you: who may be on site and when, which zones matter, what counts as a violation, who gets called and in what order. Judgement happens here — deliberately, in advance, by people who know the site.

Connect

Your cameras stream securely to the Kevlar platform — your existing CCTV for Lite and Alive, Kevlar-supplied covert systems for Covert. Sites need stable internet and backup power; for Covert, Kevlar can supply the connection with data billed in advance for the term.

SARA verifies and acts

SARA — Speaking Autonomous Responsive Agent — runs trained behavioural inference on every feed: intrusions, concealment gestures, zone breaches, after-hours movement, camera tampering. She authenticates each detection against your standing orders and, where it is a clear violation, acts on it herself — in seconds, not minutes. No queue, no hesitation, no waiting for someone to look up.

Governed and reported

Every action is logged against the rule that triggered it. An incident report is generated within five minutes and checked by a person before it reaches you — inside a ten-minute window. Humans govern the system and assure the record; they don't sit in the middle of every alarm.

The model, working

Ten seconds, start to finish.

An abstract process is easy to claim. Here is one that actually ran, at a retail mall in the North West, at 05:22 in the morning.

What happened

A white bakkie with no number plates cut the bolt on the gate and drove onto the property — inside the locked overnight window, when the standing order says nobody is on site.

SARA did not need to interpret that. It was not a judgement call; it was a rule being broken, and the rule had been written months earlier with the client.

What ran, in ten seconds

Detection — the vehicle breached the gate and was matched against the site's standing orders.

Action — on-site sirens triggered, an audio talk-down opened, and three separate armed response companies were called in the same instant.

Record — the incident report was generated within five minutes, checked by a person, and issued inside ten.

Why three calls at once, not a list: a sequential call list waits for the first company to answer before trying the second. Calling three simultaneously means the fastest available unit responds — whoever that happens to be that night — and nobody is stuck on a busy line while a crime is in progress.

Standing orders

Up to 25 rules on a single camera.

"The AI decides" means nothing unless you know what it is deciding against. SARA is not guessing at what looks suspicious — she is measuring against rules your site defined, and she delivers on that framework completely. The objectivity comes from the framework: she cannot apply it selectively, because she has no view of her own to apply.

Written per camera

Each camera can carry up to 25 standing orders of its own. The rules for a loading bay are not the rules for a customer entrance, and neither are the rules for the ATM line. One site can carry hundreds of rules in total.

Written with you

Built before go-live, in daylight, by people who know the site: who may be present and when, which zones are restricted, what counts as a violation, who is called and in what order.

Changed when you change

New shift pattern, new contractor, a zone repurposed — the standing orders are updated to match. The rules are yours; SARA's job is to enforce exactly what is written, every time, without drift.

Against a manned control room

The rule applied the same way. Every time.

Fatigue is the obvious argument, and it is real. But the bigger problem with human monitoring is subjectivity. Two operators watching the same footage reach different conclusions. The same operator reaches different conclusions on a Monday morning and at the end of a Friday night shift. SARA has no opinion to have.

A human operator

  • Judges subjectively. What counts as suspicious shifts with the person, the mood and the hour
  • Applies the same rule differently to different people — often without meaning to
  • Watches a handful of feeds properly; attention degrades sharply beyond that
  • Tires, blinks, takes breaks, changes shift, has bad nights
  • Takes minutes to verify, decide and place calls in sequence
  • Can be bribed, pressured, or simply be on the far side of the building

SARA

  • Entirely objective. She measures against your written framework, not against an impression
  • Applies the identical rule to everyone, on every shift, without exception or favour
  • Watches every camera at once, continuously, with no drop-off
  • No fatigue, no shift change, no bad nights, no salary to bribe
  • Ten seconds from detection to sirens, audio and three responders
  • Delivers on the SOP framework you built — completely, every time, without drift
Why objectivity matters beyond fairness: when an incident ends up in a disciplinary hearing, an insurance claim or a court, "the operator thought it looked suspicious" is a weak position. "The site's written standing order was breached, and here is the rule, the timestamp and the footage" is a strong one. Objective enforcement is not just fairer — it produces better evidence.
The hard rules

Built lawful by design

  • Never listening. No Kevlar camera records ambient sound. Covert deployments carry no audio at all. Where two-way audio is enabled on an overt site, SARA speaks first and audio exists only if the person chooses to answer her.
  • Behaviours, not intent. SARA acts on what people do measured against your rules — she never claims to know what they think — and uses no facial recognition or biometrics.
  • Humans govern, not operate. People write the standing orders SARA enforces, and every incident report is checked by a person before it is issued. Nothing reaches you, or anyone else, as an unreviewed machine output.
  • No armed response. Kevlar detects, verifies, routes and calls your nominated responders. We are the eyes and the evidence — your responders are the hands.
  • Operational areas only for covert work. Never bathrooms, change rooms or private spaces — and the fact of monitoring is always disclosed in the client's staff policy.
Questions people actually ask

The model, answered straight.

Does a human watch my cameras?

No — and that is the point. No person sits watching your feeds. SARA watches every camera continuously and acts on the standing orders written for your site. Humans handle governance: they write the rules SARA enforces, and after she has processed an incident they check that her processes and workflows were delivered correctly before the report is issued.

So nobody checks SARA's work?

They do, but after the event rather than in the middle of it. Every action SARA takes is logged against the rule that triggered it. An incident report is generated within five minutes, reviewed by a person to confirm the workflow ran correctly and the record is sound, and issued inside a ten-minute window.

What is SARA actually deciding against?

Your standing orders. Each camera can carry up to 25 rules of its own — who may be present and when, which zones are restricted, what counts as a violation, and who gets called in what order. They are built with you before go-live and updated whenever your operation changes.

What happens between detection and my phone ringing?

Seconds. SARA matches the detection against the standing orders, and where it is a clear violation she acts immediately: on-site alarms, audio where fitted, and simultaneous calls to your nominated responders. In a recent live incident the whole sequence ran in ten seconds.

Why call three responders at once instead of working down a list?

A sequential list waits for the first company to answer before trying the second. Calling three at the same instant means the fastest available unit responds, whoever that is on the night, and nobody waits on a busy line while a crime is in progress.

What if SARA gets it wrong?

She measures against a written rule and applies it objectively, so a wrong call almost always means the rule needs refining rather than the machine misbehaving — which is exactly what the governance review catches. She cannot be inconsistent about it; she will make the same call in the same circumstances every time, which makes a bad rule easy to spot and fix. Our liability on any monitoring claim is capped at a maximum of three months' subscription fees for the affected service, set out in your agreement.

Do your cameras record audio?

No camera records ambient sound. Covert deployments carry no audio at all. On overt sites where two-way audio is fitted and switched on, SARA speaks first and audio exists only if the person chooses to answer her — say nothing and nothing is recorded.
