Which type of alarm system provides a higher level of verification of ongoing activity?

Video surveillance systems provide a higher level of verification of ongoing activity because they allow for real-time observation and recording of events. This capability enables property owners and monitoring personnel to visually confirm whether a security alert is legitimate or if it can be disregarded as a false alarm.

In contrast, audio alarms typically only alert users to sounds, which can be ambiguous and may not provide visual context to confirm the situation. Smoke detectors are crucial for fire safety but do not provide insight into security events; they only indicate the presence of smoke or heat. Basic motion detectors can identify movement but usually lack the contextual detail necessary to verify the nature of that movement or the activity occurring. Therefore, video surveillance systems stand out for their ability to visually validate incidents, making them a more effective choice for comprehensive security monitoring.
