Security System Cost Calculator
| Equipment (hardware only) | Band | Mid |
|---|---|---|
| DIY starter kit | $200-600 | $400 |
| Pro-installed wireless | $600-1,200 | $900 |
| Hardwired whole-home | $1,500-3,000 | $2,200 |
Security systems price in two stacked layers: equipment and monitoring. Equipment runs $200-600 for a DIY starter kit (hub, door/window sensors, one camera), $600-1,200 for professionally installed wireless, and $1,500-3,000 for hardwired whole-home with cellular backup. Monitoring stacks on top year after year: self-monitoring through an app costs $20-40 a month at most, professional 24/7 monitoring with dispatch runs $40-70 a month - so the monitoring line, not the hardware, owns the ten-year cost of the system.
The monitoring decision is a response-time decision, and the data is public: the FBI Crime Data Explorer publishes burglary offense counts and, notably, the majority of residential burglaries happen in daytime hours when homes are empty - and the police response your alarm buys is worth roughly what the dispatch wait is not. A siren alone scares amateurs; a monitored alarm converts a noise into a phone call, and a verified call into a dispatch. Whether that chain is worth $40 a month depends on what the alarm actually sees and who answers it.
The honest setup advice cuts against both salesmen: most forced entries are through the front door, first-floor windows and the back door, in that order - three sensors and decent placement beat fifteen sensors badly placed. Cameras document; sensors interrupt. And the boring lines matter more than the panel: the door sweep and the deadbolt are the security system that never needs a subscription.
How to use
- Count the honest entry points first: front door, back door, first-floor windows - three to six sensors covers most homes better than a carton of motion detectors.
- Pick equipment honestly: DIY wireless if you rent or move, professional wireless for clean multi-story installs, hardwired only when walls are already open.
- Decide monitoring in months, not marketing: self-monitoring means your phone is the dispatch; professional means a center calls you, verifies, and calls again - that difference is the whole fee.
- Check the contract line that outlives the hardware: monitoring term, auto-renewal, and the buyout if you move - this is where the ten-year price hides.
Frequently asked questions
How much does a home security system cost?
Equipment runs $200-600 for a DIY kit, $600-1,200 professionally installed wireless, and $1,500-3,000 hardwired whole-home. Monitoring adds $240-480 a year self-monitored or $480-840 a year for professional 24/7 dispatch. A realistic mid-range first year - professional wireless equipment plus professional monitoring - lands near $1,600 all-in.
Is professional monitoring worth the monthly fee?
It is worth it when nobody is home to answer the phone: the center verifies and dispatches while you are unreachable, which is the majority of burglary hours. It is poor value for a retiree-home or a small apartment where you are the fastest responder. The middle path most homes land on: professional monitoring for the first year or two, then drop to self-monitoring once the habit and the placement are proven - the hardware keeps working either way.
Do security systems actually deter burglars?
The deterrence evidence points to visible components: cameras, yard signs and, above all, the interruption itself - most residential burglars prefer unoccupied homes and leave when entry gets loud, slow or visible. The FBI Crime Data Explorer entry data shows the typical burglary is daytime and unforced or minimally forced, which is why locked doors, deadbolts and lit entries move the number as much as the panel does.
Can I install a security system myself?
Yes for wireless DIY kits - sensors peel-and-stick, the hub pairs by app, and moving means unscrewing nothing. Professional install earns its fee on multi-story wireless routing, hardwired runs, and integration with existing wiring. The one line to hand over regardless: anything that ties into the electrical panel or requires a cellular communicator activation under a contract you have not read.
What is the cheapest way to secure a home?
The zero-subscription stack: grade-1 deadbolts on all exterior doors, 3-inch screws in strike plates and hinges, door and window locks actually used, motion lighting at entries, and a visible camera or two. That stack addresses the unforced-entry majority and costs a weekend. Every dollar after it buys detection and response, not prevention - price it as a separate decision.
