An alarm is only as good as the response after it
Choose monitoring by building the complete chain: detection, communication, verification, decision, escalation, attendance, reset and review. A loud siren or app alert is not itself a response plan.
Self-monitored
Alerts go to you or chosen contacts. It is flexible and often lower cost, but depends on phones being reachable and somebody being able to act.
Professionally monitored
A monitoring centre receives signals and follows an agreed procedure. Confirm verification, escalation, keyholder and attendance terms.
Hybrid
You may self-monitor routine events while defined alarm types go to a professional service. Check how modes and failure paths interact.
Build the response chain
| Stage | Questions to answer |
|---|---|
| 1. Detect | Which sensor triggered? Can the system distinguish intrusion, fire, panic, water and equipment faults? |
| 2. Communicate | Is the path broadband, cellular, landline or a combination? What happens during power or internet loss? |
| 3. Verify | Is verification by a second sensor, video, audio, a call or an on-site check? Who is permitted to view footage? |
| 4. Decide | Who decides whether to call a keyholder, guard, emergency service or nobody? |
| 5. Escalate | What order are contacts called in? What if nobody answers or gives the wrong passcode? |
| 6. Attend | Is attendance included, chargeable or unavailable? Are police or guard responses conditional? |
| 7. Reset and review | Who secures the property, repairs damage, resets sensors and preserves relevant recordings? |
Compare the real failure modes
- Your phone is silent, flat, abroad or outside coverage.
- Broadband or mains power has failed.
- A pet, open window or user error creates repeated false alarms.
- The primary keyholder is unavailable or too far away.
- The intruder damages an external bell, hub or visible cable.
- The subscription ends, a payment fails or equipment loses support.
Questions for any provider
- Who operates the monitoring centre, and which standards or licences apply?
- Which signals are monitored and for how many hours each day?
- What verification is required before escalation?
- Are cellular backup, maintenance and call-outs included?
- Who owns the equipment, recordings and app account?
- What are the minimum term, price rises, cancellation and moving-home rules?
- What happens after repeated false alarms?
