Cable crossing for access control is a security measure that is used to restrict access to certain rooms or areas to only authorized individuals. It is a type of barrier or gate that opens and closes based on an electronic signal.

Cable crossings are often used to restrict access to secured areas such as parking garages, data centers, offices, or buildings. They can be integrated into an access control system and operated using card readers, fingerprint readers, or other technologies.

Cable crossings are effective at restricting access to secured areas because they are difficult to bypass. They are also an effective way to record who has access to certain spaces and when, which can help with compliance with laws and regulations, reducing theft, and improving overall security.
