Which component of the IDS system is a sensor that detects movement?

• A. Motion Detector
• B. Data Transmitter
• C. Tamper Switches
• D. Permatrax

Answer: (A)

Movement detection in an intrusion system is handled by a motion detector, a type of sensor. It watches a space and triggers the alarm when it detects movement, using technologies like passive infrared, microwave, or dual-technology sensing. This is its primary role, so it’s the best answer. The data transmitter’s job is to relay signals from sensors to the monitoring system, not to sense movement. Tamper switches monitor for attempts to disable or open the device, not for motion in the protected area. Permatrax isn’t a standard movement sensor in IDS configurations.
