Today's digital, network video surveillance systems are far superior than yesterday's analog systems. Digital cameras have a much higher image quality and can see in both day and night. Other advantages over analog include remote accessibility, easy installation and integration, better scalability, flexibility and cost effectiveness.

Perhaps the biggest advantage is the intelligent capabilities of the new digital surveillance systems. Today's systems have features such as video motion detection, audio detection alarm, active tampering alarm, temperature alarm, and event management. Video analytics allow these systems to detect an event and automatically respond to and event with actions such as video recording and sending alarm notifications.
