<p>PROBLEM TO BE SOLVED: To provide a car security device which is set to the security operation without operation when during the security operation, a power supply wire is disconnected and then put in the connecting state again. SOLUTION: A car security device comprises a condition detecting part 3 including sensors 10-13 for detecting the condition, a warning generating part 4 for informing a theft by warning in the case of abnormality, and a security device main body part 2 for selectively operating the warning generating part 4 in response to the output of the condition detecting part 3, wherein the device main body part 2 monitors the output of the condition detecting part 3 during the security operation, and performs the transition to the alarm operation to operate the warning generating part 4 when there is abnormality in any output. A memory 9 for storing the condition of security operation for the security operation is provided in the device main body part 2. When the connection between the device main body part 2 and an on-vehicle power supply 5 is once cut off during the security operation and then the device main body part 2 and the on-vehicle power supply 5 are again connected to each other, the device main body part 2 is reset to the security operation according to the storage content of the memory 9.</p> |
