CCTV (Closed Circuit Television) refers to a system where cameras are used to transmit signals to a specific, limited set of monitors or recording devices. It is mainly used for surveillance and security purposes.
Regular maintenance includes cleaning the camera lenses, checking the connections, testing recording functions, and ensuring there’s enough storage space. Additionally, it's important to check for software updates regularly.
RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. In security systems, it’s used for access control, allowing secure entry based on RFID cards.
