CCTV

closed-circuit television (CCTV) is a system that uses cameras to transmit a signal to a specific place, on a limited set of monitors. Unlike broadcast television, which sends its signal to anyone with a receiver, CCTV systems are designed to send their signal only to a designated place. This makes CCTV systems ideal for security applications, where it is important to monitor specific areas without broadcasting the images to the public

Access control

Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to a business or organization.

Access control systems perform identification, authentication, and authorization of users and entities by evaluating required login credentials. These credentials can include passwords, personal identification numbers (PINs), fingerprint ID, security tokens, or other authentication factors.
