Updated September 13, 2026 · SecurityVerdicts research desk

Security systems are often sold on monthly price or discounted equipment. The useful comparison is total ownership cost over the period you expect to keep the system.

Calculating…

What to include

Add equipment, required hubs, installation, monitoring, cloud recording, cellular backup, extended warranty costs and likely replacement batteries. Subtract discounts only if you actually qualify without adding a more expensive contract.

Why five-year cost changes decisions

A professionally monitored system can provide services a self-monitored setup does not, but the recurring fee dominates total cost over time. Compare the service outcome, not just device count.
