Monitored vs Unmonitored Security: What Actually Differs
One dispatches police when you are unreachable. The other costs nothing ongoing and carries no term. Both are legitimate; they solve different problems.
The Short Answer
Monitored security is the only version that does anything when you are asleep, abroad or ignoring your phone — an operator sees the alarm and dispatches. Unmonitored costs nothing ongoing and carries no term, and for a household that mainly wants a deterrent and a recording, that is a legitimate choice rather than a lesser one.

The Full Comparison
Every row is a verifiable specification, and the advantage marker says which side wins it. Where monitored loses, the table says so.
| Specification | Monitored | Unmonitored |
|---|---|---|
| What happens on an alarm | Monitoring centre receives the signal, calls your contacts, dispatches police or fireAdvantage: left | Local siren sounds and your phone gets a notification. Nothing else happens. |
| Response when you are unreachable | Escalation continues without you — dispatch happens whether you answer or notAdvantage: left | None. If your phone is off, the alarm is a noise in an empty house. |
| Signal path | Cellular primary with broadband secondaryAdvantage: left | Broadband only |
| Behaviour if broadband is cut | Cellular path carries the signal; the system reports normallyAdvantage: left | Notifications stop entirely; only the local siren works |
| Monitored smoke and fire | Available — the monitoring centre is notified when the house is emptyAdvantage: left | Not available; a smoke detector alerts whoever is present |
| Medical and panic escalation | Panic button and duress code route to an operatorAdvantage: left | App notification only |
| Contract term | 36-month monitoring term | NoneAdvantage: right |
| Ongoing commitment | Monthly monitoring agreement for the length of the term | No ongoing commitment of any kindAdvantage: right |
| Early termination | Prorated charge against remaining monitoring months | Nothing to terminateAdvantage: right |
| Equipment ownership | Owned outright from day one | Owned outright from day one |
| Insurance discount eligibility | Most insurers recognise a centrally monitored system; a certificate is issuedAdvantage: left | Rarely recognised — insurers generally require central station monitoring |
| Local permit requirement | Many municipalities require an alarm permit for a dispatching system | No permit, because nothing is dispatchedAdvantage: right |
| False alarm exposure | Repeat false alarms can attract municipal charges | No municipal exposureAdvantage: right |
| Install | Professional, with a live test signal to the monitoring centre | Self-install is realistic; professional available |
| Battery backup | 24 hours, system stays armed and reporting through a power cutAdvantage: left | 24 hours, but with broadband down it reports to nobody |
| Upgrade between the two | Downgrading to unmonitored ends the term early and triggers the charge | Upgrading later may require a panel swap on some hardware |
Across 16 specifications: Monitored leads on 8, Unmonitored leads on 5, 3 are level.

Choose Monitored if
- The house is empty for long stretches — you travel, you work nights, or it is a second property nobody is at midweek
- You want monitored smoke detection, which is the single feature people most often regret not having and cannot be replicated by a hardware-store alarm
- Your insurer offers a premium reduction for a centrally monitored system, which changes the arithmetic
Choose Unmonitored if
- You are renting, moving inside three years, or otherwise unwilling to sign a 36-month term — this is the most common and most sensible reason
- Someone is almost always home, and what you actually want is a deterrent, a recording and a doorbell you can answer from the sofa
- You have an existing neighbour or family arrangement for checking the property, which is the informal version of what a monitoring centre does
What the Spec Sheet Does Not Tell You
Four things that decide how this actually goes, none of which appear on a datasheet.
- The permit is the part nobody mentions. A monitored system that can cause a police dispatch usually needs an annual municipal alarm permit, and an unpermitted dispatch typically carries a charge. It is a small piece of admin that turns into an unpleasant surprise precisely at the moment the system did its job.
- Support routing differs more than the specification suggests. On a monitored system there is an operator with a defined escalation, which means a real person is accountable at 3am. On an unmonitored one, an alarm at 3am is a notification competing with your phone being face-down on a nightstand.
- The 36-month term is the real decision, and it is a household-circumstances question rather than a security one. Most people who regret a monitoring contract regret the timing, not the service — they signed it eight months before a move they already half expected.
- False alarms behave differently. On a monitored system they cost you goodwill with your municipality and eventually money. On an unmonitored one they cost you nothing except your own attention, which is a genuine advantage for a household with pets, teenagers and a side door that does not quite seat properly.
Common Questions
Can I add monitoring later to an unmonitored system?
Sometimes. Some panels carry the cellular radio already and monitoring is a provisioning change; others need a panel swap. It depends on the hardware you started with, so it is worth confirming before you buy if you think you might want monitoring later.
How fast does the monitoring centre actually respond?
The signal reaches the centre within seconds. The operator then calls the primary contact, then the secondary, before dispatch. Where video verification is available the operator reviews the clip first, which adds a few seconds but means police treat it as a confirmed intrusion.
Do I need a permit for a monitored alarm?
In many municipalities, yes — any system that can cause a police dispatch requires an alarm permit, renewed annually. We flag whether your city requires one during the call, because an unpermitted dispatch usually carries a charge.
What is a duress code?
A second disarm code that appears to switch the system off normally but silently signals the monitoring centre that you are being forced to disarm it. It exists precisely for the scenario where the alarm has already been defeated.
Is a loud siren not enough on its own?
For opportunistic entry, often yes — noise ends most attempts quickly. It does nothing for a fire in an empty house, nothing at a property where neighbours are not close enough to hear, and nothing to produce a police response. That gap is what monitoring buys.
Work Out Which One Suits Your Home
The right answer depends on your floor plan, your housing stock and how often the house is empty. It is a five-minute conversation.
