Vehicle security glossary

Compare car alarms, remote start systems, two-way paging remotes, smartphone control and installation accessories before choosing the right vehicle-security system.

Basic Vehicle Alarm

A traditional car alarm system designed to detect unauthorized entry, impact or attempted vehicle theft. Most systems include a siren, starter-disable output, door-trigger monitoring and security remotes.

Best for: Adding dependable theft protection without remote start.

Remote Start System

A remote car starter turns on the vehicle from a compatible remote while the doors remain locked. It allows the factory climate-control system to begin heating or cooling the interior before the driver gets inside.

Best for: Improving comfort during hot summers and cold winters.

Remote Start + Alarm

A combination alarm and remote-start system provides engine-starting convenience and vehicle security in one package. It can control starting, locking, unlocking, impact detection, alarm triggers and other supported functions.

Best for: Drivers who want theft protection and remote-start convenience together.

Two-Way Paging Alarm + Remote Start

A two-way vehicle-security system sends confirmation back to the remote when the vehicle receives a command or triggers the alarm. Depending on the model, the remote may confirm engine start, locking, unlocking and security alerts through lights, sounds, vibration or an LCD display.

Best for: Extended operating range and confirmation that the vehicle responded.

Smartphone Alarm + Remote Start

A smartphone-controlled alarm and remote-start system adds connected vehicle control through a compatible mobile application. Available features may include remote starting, locking, unlocking, vehicle-status updates, security notifications and GPS-related services.

Best for: Connected control without relying exclusively on a traditional remote.

A compatible module, mobile application and paid service plan may be required.
