CCTV systems are used for surveillance and security purposes. They consist of cameras placed strategically to monitor specific areas. They are commonly used in public areas, businesses, and homes to deter crime, monitor activities, and provide evidence if incidents occur.
These systems regulate who can enter certain areas or access specific resources. They often include keycard access, biometric scanners (like fingerprint or retina scanners), or PIN code entry systems. Access control systems enhance security by ensuring that only authorized individuals can enter restricted areas.
Alarm systems are designed to alert people to potential security breaches, such as unauthorized entry or fire. They can include sensors for doors and windows, motion detectors, and smoke detectors. When triggered, they emit loud sounds and/or send alerts to designated contacts or monitoring services.
