Security Β· ARC monitoring

Your building sleeps.
We don’t.

An unmonitored alarm is a request for a neighbour to care. A monitored one is a process — signal, verification, action — that runs whether you are on site, asleep or abroad. Gemini AMPM was built around out-of-hours cover; the AM and the PM in the name are a promise about the clock.

Signal to action

Every signal answered.
Every action logged.

When a signal lands at the alarm receiving centre, a process starts. Operators filter it against your site instructions — open zones, expected keyholders, known engineering works — and verify whether it is real. Confirmed intruder events go to police under your URN. Fire signals go straight to the fire service. Detector-activated CCTV gets human eyes on live footage within seconds of the trigger.

Then someone attends. Our keyholder response service puts a professional on site to meet police, secure the building and reset the system, so your staff are never sent alone into a dark premises at three in the morning to investigate a noise. Every step — signal, decision, arrival time, outcome — is timestamped, because an unwitnessed response is just a story.

What we deliver

Scoped, delivered,
evidenced.

  • ARC monitoring — intruder, fire and detector-activated CCTV signals received, verified and acted on around the clock.
  • Keyholder response — professional attendance to activations, so staff are not sent into dark buildings alone.
  • Police escalation — confirmed alarms passed under your URN for a response with weight behind it.
  • Cloud reporting — every event, action and outcome logged under NSI NCP 104 and readable the next morning.
  • Out-of-hours cover — nights, weekends and bank holidays are the point of the service, not the exception.
  • 24-hour engineers — a named engineer on call around the clock, not a ticket queue answered in the morning.
We own the night

Out of hours is
home ground.

The name gives it away. AM:PM was built for the hours when nobody else answers — nights, weekends, bank holidays — and out-of-hours cover has been the backbone of the business since 1997. A 24-hour named engineer comes as standard on every contract: a person whose name you know, not a ticket number in a queue.

Monitoring you cannot inspect is monitoring you take on faith, so we run cloud-managed reporting under NSI NCP 104. Every activation, operator decision, keyholder attendance and engineer visit is logged and readable the next morning — evidence for your insurers, ammunition for budget conversations, and an honest record of how your sites really behave after dark. If the reports show a problem, we fix the system, not the narrative.

FAQ

Common questions on
monitoring.

What actually happens when my alarm goes off at 3am?

The signal reaches the alarm receiving centre within seconds. Operators check it against your site instructions and its confirmation status: a confirmed intruder event is passed to police under your URN, a fire signal goes to the fire service, and monitored CCTV is viewed live to verify what is happening. Keyholder response attends to secure and reset the site. You get the full timeline in your report — most clients read it over breakfast.

Can you monitor a system you did not install?

Usually, yes. We survey the existing system, confirm it can signal reliably over a monitored dual-path connection, and bring it under our maintenance so the monitoring actually means something. Takeovers of orphaned or poorly maintained systems are routine for us. If the system cannot support monitoring as it stands, you get a straight answer and a costed remedial plan — not a contract for signals nobody can act on.

Do we still need staff keyholders?

Not on the front line. Nominated contacts stay on record, but professional keyholder response means a trained responder attends activations, meets police, secures the premises and resets the system — instead of an employee driving across town at 3am, tired and alone. That removes a genuine lone-worker risk and makes response times consistent. Many clients keep one senior keyholder for escalation decisions and let us handle everything physical.
