We tested these budget-friendly car alarms for two weeks. Each system faced daily use and simulated break-in attempts.
Our team measured sound levels, remote range, and ease of use. We also tracked installation time for DIY options.
Our Testing Process
We installed each alarm in different vehicle types. We tested detection accuracy with various intrusion methods.
Every system underwent at least 30 arm/disarm cycles. We measured actual decibel levels from 10 feet away.
