ABSTRACT:
A car security apparatus and a car security system for protecting a vehicle from car theft and tampering which notifies a user of the details regarding an abnormal condition (i.e., the identity of the sensor or sensors that have detected the abnormal condition, and the time of detection) that takes place during the activation of a security function of the apparatus. When any sensor detects an abnormal condition with the security function in an armed (on) mode, a controller stores in a memory device the identification of the sensor that detects the abnormal condition and the time of detection as security information. In response to a predetermined operation performed the user, the controller reads the security information from the memory device and transmits the security information to another onboard device (audio or audio/visual device) having a display. The device receives and then presents the security message using alphanumeric characters on the display.
