1：What is it?
A car alarm system is a security device installed inside a vehicle that alerts the owner by emitting a warning sound when it detects abnormal opening or closing of doors or unusual vibrations on the vehicle's body.
2：Did you know?
The car alarm system automatically activates after the vehicle is turned off and locked.
Once the alarm system is activated, there will be a flashing indicator light usually located near the front window, under the windshield, or on the dashboard.
The alarm sound not only alerts the vehicle owner but also acts as a deterrent to discourage theft attempts.
3：Drawbacks
The sensitivity of the alarm system can be too high or too low, causing false alarms in situations such as thunderstorms or loud fireworks, leading the owner to mistakenly believe that the vehicle is being stolen. Frequent false alarms can also contribute to noise pollution. On the other hand, if the sensitivity is too low, the alarm may fail to trigger in case of an actual theft.
