Most homeowners don't shop for security until they need it — after a break-in, a move, or a life event. By then, you're making decisions under pressure and the security companies know it. This guide takes you through every decision in order so you can make a thoughtful choice.
Step 1: Decide your monitoring level
Three options. Self-monitoring (you watch alerts yourself through the app, $0-$15/month) is fine if you're typically home, attentive to your phone, and your primary need is video evidence rather than emergency response. Limited professional monitoring ($20-$45/month) provides app-tier oversight with some response capabilities but typically not full police dispatch. Full professional monitoring ($45-$100/month) through a UL-listed central station provides 24/7 staffed dispatch with police coordination.
If you have small children, valuable assets, frequent travel, or live in a higher-crime area, full professional monitoring usually pays for itself. If you're young, attentive, and live in a low-crime suburban area, self-monitoring may be sufficient.
Step 2: Decide professional vs DIY install
DIY install saves $99-$499 upfront but typically results in suboptimal camera placement, network issues, and reduced effectiveness. Professional install costs more but provides better coverage, ongoing support, and a single accountable contact. See our DIY vs Professional Installation guide for the complete comparison.
Step 3: Avoid 36-month contracts
ADT, Brinks, Vivint, and other traditional security brands typically require 36-month or 60-month contracts. The 'discount' offered for the contract is usually less than the cost of being locked in. If your situation changes — you move, service drops, you find a better option — early termination fees can run thousands of dollars. Modern providers like Halstead, Ring, and SimpliSafe offer month-to-month or 12-month commitments instead.
Step 4: Compare hardware quality
Consumer-grade hardware (Ring, SimpliSafe) is designed for ease of DIY installation but typically fails after 3-5 years. Commercial-grade ONVIF cameras (Halstead, professional security companies) cost more but last 7-10+ years and provide better resolution, night vision, and weather resistance. Over the life of the system, commercial-grade is usually cheaper because you don't replace it as often.
Step 5: Evaluate smart features
Beyond basic motion alerts, modern systems offer features that meaningfully improve daily life: AI motion classification (person/vehicle/package/animal), vacation mode automation, family check-ins, visitor passes, smart escalation, and storm mode. Most established brands (ADT, Vivint) offer some of these on top tiers; modern brands (Halstead, others) include them at lower tiers.
Step 6: Calculate total 5-year cost
Add up: hardware + activation + (monthly fee × contract length) + likely renewal + any guaranteed price escalations. Compare across vendors at this 5-year level rather than just monthly. The cheapest monthly fee often comes with the longest contract, which means the highest total cost. Real value usually comes from balanced pricing with shorter commitment.
Step 7: Check insurance discount
Most homeowners insurance policies offer 5-15% discounts for monitored security systems. Confirm with your insurance carrier what their discount is and which monitoring level qualifies. Some companies (Halstead) automatically submit certificates annually so you actually receive the discount. Factor the realized discount into your total cost calculation.
Step 8: Look at the company's local presence
When something goes wrong (and eventually something always does), can you reach a real person? Local-dealer brands like Halstead provide a direct phone line to your installer. National-only brands route everything through call centers. The difference in customer experience is significant, particularly for non-emergency service issues.
