Security hardware refers to physical devices designed to protect property and information from unauthorized access or damage. Common examples include locks, security cameras, and alarms. These tools help deter crime and provide a sense of safety in homes and businesses. In addition to traditional locks, modern security hardware may include biometric scanners that use fingerprints or facial recognition for access. Other devices, like motion sensors and smart locks, can be integrated into a broader security system, allowing for remote monitoring and control through smartphones or computers.
