Anti-theft systems are security measures designed to prevent theft and protect valuable items, such as vehicles and property. These systems can include alarms, immobilizers, and tracking devices that alert owners or authorities when unauthorized access occurs. They are commonly used in cars, homes, and businesses to deter potential thieves. Many modern anti-theft systems are equipped with advanced technology, such as GPS tracking and smartphone integration, allowing users to monitor their belongings remotely. Some systems can even send notifications to the owner's phone if suspicious activity is detected, enhancing overall security and peace of mind.
