Which of the following describes a Personal Emergency Response System (PERS)?

• A. A small radio, a transmitter, a console connected to your telephone, and an emergency response center that monitors calls.
• B. A base station, a GPS module, a cloud server, and a wearable device.
• C. A siren, a control panel, a battery pack, and a motion sensor.
• D. A camera, a monitor, a microphone, and a router.

Answer: (A)

A Personal Emergency Response System provides immediate access to help through a wearable alert that the user carries, a home base that connects to the telephone line, and a monitoring center that receives the alert and can dispatch assistance. The described setup fits this exactly: a small radio transmitter worn by the person, a console linked to the telephone, and an emergency response center that monitors calls. The other options describe different technologies—GPS/cloud-based systems, traditional alarm components with sirens, or surveillance setups—not the typical PERS configuration focused on rapid, personal alerts to a monitoring center.
