2) plug-piece, push-button remote control and so are electronic anti-theft devices, which rely mainly on the ignition lock or to start
Achieve security purposes, but also has anti-theft alarm and sound.

3) GPS satellite positioning vehicle anti-theft system is a network-based security, which mainly by locking the ignition or starter to achieve security purposes, while also through the GPS satellite positioning system (or other network systems), alarm information and alarm vehicle location silently sent to the alarm center.

Second, the remote control car alarm features
