We tested these car alarms for four weeks in high-theft areas. Each system faced real-world tests in various vehicles.
Our team measured response time, detection accuracy, and installation difficulty. We also checked remote range in different environments.
Our Testing Process
We installed each alarm in multiple vehicle types. We measured the failsafe starter kill response time with specialized equipment.
Our team tested each system day and night. We even had security experts attempt to bypass each system.
