How popular options are structured
The important difference is not just the logo on the box. Some plans charge per camera, others cover a whole home, and professionally monitored bundles may exchange a longer term for bundled equipment.

Buying guide
Spend on the protection you will actually use
Self-monitored
Your cameras and sensors send alerts to your phone, and you decide whether to call for help. It keeps monthly costs low but puts response on you.
Good for condos, rentals and confident DIY users
Look for useful free features before assuming a plan
Battery devices are easy to place but need maintenance
Professionally monitored
A monitoring centre receives alarm events and can follow an escalation process. The service cost matters more than hardware over a three-year term.
Ask who owns and operates the monitoring centre
Check cancellation, moving and renewal terms
Confirm cellular backup and power-outage behaviour
What pushes cost up
Outdoor cameras, continuous recording, video verification, long cable runs and ladders add cost faster than basic contact sensors.
Weather-rated cameras usually cost more than indoor units
Cloud history may be priced per device or per home
Professional wiring can be worthwhile for permanent installs
Before you sign a term
Compare the minimum contract cost—not just the promotional month. Ask what happens to financed or bundled equipment if you cancel early.
Get the regular price after the promotion in writing
Check whether equipment is owned, rented or financed
Review municipal alarm permit and false-alarm rules
Check your city or county's alarm permit, registration and false-alarm rules

Insurance note
Ask your insurer before you buy for a discount
Many Canadian insurers may offer a discount for an eligible, centrally monitored alarm, but a camera-only or self-monitored setup may not qualify. Requirements and savings vary. Ask which monitoring certifications and proof they require, then compare the annual discount with the annual monitoring cost. IBC also recommends setting your security system as part of its personal-property theft-prevention guidance.
Some US insurers may offer a discount for an eligible centrally monitored alarm, but qualifying systems, documentation and savings vary by state and insurer. Ask your carrier what proof it requires, then compare any annual discount with the annual monitoring cost.

How this estimate is built
This is a planning model for a typical Canadian residential setup, not a retailer cart or installer quote. It deliberately uses rounded 2025–2026 allowances so a temporary promotion does not distort the three-year picture.
This is a planning model for a typical US residential setup, not a retailer cart or installer quote. Its rounded equipment and plan allowances are anchored to published manufacturer pricing checked October 4, 2026, so the result is representative rather than a temporary sale quote.
EquipmentSystem-type base kit plus per-camera, per-sensor and per-doorbell allowances.
InstallationDIY is $0 labour. Professional installation adds a setup allowance plus device-by-device labour.
InstallationDIY is $0 labour. The $550 professional-install allowance reflects the difference between ADT's published DIY and professionally installed equipment totals for the same example bundle.
MonitoringYour chosen tier is held for 36 months. A professional-system selection carries a minimum professional-monitoring allowance.
ContractChanges the minimum monitoring commitment shown, not the 36-month ownership total. Service is assumed to continue for the full three years.
RangeThe practical range is ±15% around the modelled total. Complex wiring, premium hardware and remote-area labour can exceed it.
FAQ
Common cost questions
How much does a home security system cost in Canada?
A small DIY setup can start in the low hundreds before tax, while multi-camera systems with professional installation can reach well into four figures. Monitoring commonly adds an ongoing monthly cost. Use the calculator to size the equipment and see the 36-month effect.
Is professional monitoring worth the monthly cost?
It can be valuable when you want someone else to respond while you are asleep, travelling or unable to check an alert. Compare response procedures, cellular backup, contract terms and possible insurance savings—not just the monthly price.
Can I use security cameras without a subscription?
Many cameras provide live view and basic alerts without a subscription, but recorded history, smart detection and sharing often require a paid plan or compatible local storage. Confirm features for the exact device before buying.
Do monitored alarms reduce home insurance premiums?
Some insurers offer discounts for eligible centrally monitored systems. The amount and qualifying equipment vary by insurer, and self-monitored cameras may not qualify. Ask your insurer what documentation it needs before purchasing.
What hidden costs should I budget for?
Allow for tax, batteries, optional cloud storage, internet, professional wiring, alarm permits, false-alarm fees, early cancellation charges and replacement devices outside warranty.
Does a longer contract lower the total cost?
Not necessarily. A promotion may reduce the advertised monthly fee or bundle equipment, but it also increases your minimum commitment. Compare the regular rate, equipment ownership and cancellation terms over the same three-year horizon.
How much does a home security system cost in the US?
Published manufacturer examples range from low-cost individual cameras to multi-piece alarm kits in the hundreds of dollars before tax. Professional monitoring adds an ongoing monthly cost; the US calculator sizes the equipment and shows the 36-month effect in USD.
