What is needed on a DVR to trigger real-time recording of an alarming camera?

• A. Alarm inputs
• B. Motion sensors
• C. Time schedule
• D. Remote login

Answer: (A)

Triggering real-time recording from an alarm relies on the DVR’s alarm input capability. An external alarm device—such as the alarming camera or a connected sensor—sends a signal into the DVR through an alarm input. When that input goes active, the DVR starts recording the associated camera feed immediately. Time schedules control when recording occurs regardless of events, remote login is about accessing the system, and motion sensors can trigger recording only if the system is configured for motion-triggered events. The direct mechanism for an alarm to prompt immediate recording is the alarm input.
