Alarm Monitoring: Self-Monitoring, ARC and the EN 50131 Grade Concept
Two monitoring paths -- a self-monitoring app or a professionally staffed Alarm Receiving Centre (ARC) -- and the EN 50131 security-grade concept, explained the way a certified installer would: as tradeoffs, not a single right answer.
How monitoring and grade decisions get made
Map the monitoring path to the risk
Self-monitoring via app keeps cost and complexity low but depends on someone seeing and acting on the notification; an ARC connection adds a professionally staffed response procedure at an ongoing cost. Many projects run both.
Understand what an ARC actually does
A central monitoring station verifies the alarm, contacts keyholders, and escalates to the police or a keyholding/response service according to an agreed protocol -- a defined procedure, not a promised response time.
Treat EN 50131 grade as a risk-and-insurer question
The grade reflects the level of risk a system is designed to resist. We won't tell you which grade fits your project here -- that's a risk assessment your certified installer runs, often against a minimum your insurer requires.
Plan CCTV and smart-home integration without weakening the core
CCTV adds visual verification of an alarm event; smart-home layers can extend what happens on arming or a triggered zone. Neither should replace the alarm's own detection and monitoring reliability.
Monitoring architecture and the grade concept
EN 50131 defines four risk-based grades
From lower-risk residential scenarios up to higher-risk commercial or high-value sites. Which one fits your project is a risk-assessment and insurer question for your certified installer -- not something this page prescribes.
Self-monitoring via app
Sends the alarm straight to the owner and anyone else configured. Low cost and complexity, but there's no guaranteed response if a phone is off, asleep, or out of signal.
ARC / central monitoring station
A professionally staffed Alarm Receiving Centre verifies the alarm, contacts keyholders, and escalates according to an agreed protocol -- typically at an ongoing subscription cost, arranged directly with the monitoring provider.
Running both together
App notifications give the owner immediate personal awareness; the ARC connection adds a guaranteed response path. Neither path is universally 'better' -- it's a deliberate cost-versus-response tradeoff.
EN 50131 grade, as a concept
Grades broadly reflect the risk level a system is designed to resist, and insurers may require a minimum grade for certain risk categories. We deliberately don't state which grade fits your building -- confirm that with your installer and insurer.
CCTV and smart-home integration
CCTV gives visual verification of an alarm event -- live look-in or a saved clip -- useful for the owner and, on monitored systems, for the ARC assessing a genuine alarm versus a false one. Smart-home automations can extend the system, but core detection and monitoring should stay reliable independent of that layer.
What we plan with you
Monitoring architecture and grade orientation are project decisions we work through with your team before any equipment gets specified.

- {'t': 'CCTV and smart-home integration mapping', 'd': "Where visual verification and automation add value, without weakening the alarm's own detection and monitoring reliability."}
Frequently asked questions
What's the real difference between self-monitoring and an ARC connection?
Self-monitoring sends alerts straight to your phone -- fast and low-cost, but only as reliable as someone seeing and acting on the notification. An ARC connection routes the alarm to a professionally staffed centre that follows a defined verification and escalation procedure, usually for an ongoing subscription.
Can I combine app notifications with an ARC connection?
Yes -- many installations run both, so the owner gets immediate personal awareness through the app while the ARC connection provides a guaranteed, professionally managed response path.
Which EN 50131 grade do I need?
We won't tell you on this page, and be wary of anyone who does without seeing your project. Grade selection depends on a proper risk assessment and, very often, your insurer's requirements -- get both from a certified installer before designing to a grade.
Does adding CCTV remove the need for alarm monitoring?
No. CCTV adds visual verification of what triggered a zone -- useful for the owner and, on monitored systems, for the ARC judging a genuine alarm from a false one -- but it doesn't replace the alarm's own detection and monitoring path.
How long should the backup battery last during a power cut?
That's scope-dependent and gets calculated per project, based on your risk assessment and how quickly a fault would be noticed and fixed -- not a figure we'd quote as a universal default.
Planning a monitoring architecture or grade orientation?
Our engineers can walk through self-monitoring versus ARC, explain the EN 50131 grade concept for your project, and coordinate the CCTV and smart-home integration around it -- talk to us before you commit to a monitoring provider.
