What is the function of latches in security systems?

Latches play a vital role in the overall security of a physical space by securing doors and windows. When properly engaged, latches create a barrier that prevents unauthorized access, thereby protecting the premises from intruders. They are often an integral part of a locking mechanism, providing a simple yet effective way to ensure that doors and windows remain closed and secure, contributing significantly to physical security measures.

While surveillance is important in security systems, latches do not provide surveillance capabilities. Identifying individuals typically involves biometric systems or access control methods, which are distinct from the mechanical functions of latches. Detecting fire hazards is a specialized function handled by fire detection systems, again not applicable to the role of latches in securing openings. Hence, the primary purpose of latches is clearly to enhance security by securing physical barriers.
