The Netwatch system is recording at protected sites 24/7, and this is saved for predetermined time. There is not an individual watching a client site 24/7. Once the security system is armed the Netwatch software, Cratos, knows to look for unusual activity at this site. If any rules are broken e.g. someone attempts to cross the perimeter or open a restricted door, Cratos sends an alert to an Intervention Specialists in a Monitoring Centre within seconds. At this time someone will move to a live view of the site and assess the situation. The highly trained team will determine if there is a problem and deal with it in an appropriate manner.
