Rotational angle between the two sampling points is 60 °.
Benefits:
① Mature program supports detection angle expansion.
Angle range: Horizontal 120 ° or 180 ° / Vertical 60 °.
② low cost.
1 sensor + 1 motor to achieve functional
and flexible angle selection.
③ Quick scanning, Updated time as following:
120 ° scene -> 1.2S (pause) *2 + 1.6s (rotation) = 4s;
180 ° scene -> 1.2S*3 + 1.6s *2 = 6.8s
Benefits:
① mature program supports detection angle expansion.
Angle range: horizontal 120 ° / Vertical 60 °；
② Don’t need the drive mechanism, reliable performance；
③ Real-time data updated，support source-tracking function,
support statistics of human activity .
Base on 120 ° angle ,Two Sensor installed.
Angle of Single Grid-eye: horizontal / vertical average is 60 °, it is not enough.
