In security, what is the function of a tamper switch?

A tamper switch is designed specifically to detect unauthorized access to a secure area or property and to alert the relevant security systems when such an event occurs. Typically installed on doors, windows, or various types of enclosures, the tamper switch activates when it senses that someone is attempting to bypass or breach a security measure—such as when a door is opened or a case is disturbed. This immediate detection capability is crucial for quickly responding to potential security threats, making the tamper switch an integral part of intrusion detection systems.

The other options do not align with the primary purpose of a tamper switch. Periodic resetting of alarms is not its function, as that would involve maintaining system functionality rather than detecting breaches. Enabling remote monitoring involves different technologies that communicate status or alerts but don't specifically relate to the role of tamper detection. Finally, providing user credentials pertains to access control and authentication mechanisms, which do not fall under the purview of a tamper switch’s functionality.
