This alarm system monitors all possible entry points and a motion detector can be added if desired. A compact timing system provides an approximate 13-second delay upon opening the door, allowing plenty of time to enter the car and disarm the system before the alarm sounds; the alarm sounds instantly when the hood is opened. Some useful circuit modifications are also given.
