Frequently asked questions

  • Each event costs its severity weight (low 1, medium 3, high 6, critical 12) multiplied by one plus its minutes divided by ten, capped at 30 minutes. The total is divided by the person-hours observed over ten, and the result is taken from 100. A is 90 and above, then B, C, D and F in steps of ten.

  • So the score is a rate, not a count. A busy day shift is not punished for having more people in view than a quiet night.

  • No. A supervisor can mark an event as a false alarm with a reason, such as a parked vehicle or a wrong object, and it is excluded from the score.
