Figure 75: Max Queued Reports
GPS Always On
This option forces the GPS receiver to remain ON in between reports allowing the
SHOUT sp to have immediate location information (GPS hot start assuming the
SHOUT sp always has full view of the sky) each time it is ready to transmit a tracking
report. When power consumption is not critical, enabling this option is
recommended for faster GPS acquisition and more accurate location information.
Max Queued Reports
This option sets the maximum number of reports that can be queued on the SHOUT
sp for re-transmit. This setting applies only if either Queue Failed Reports or Queue
Restricted Reports are enabled.
Motion
The SHOUT sp has a built-in sensor that can reliably detect motion. The Motion
setting, shown below in Figure 78, offers users a way to detect different motion
characteristics without having to interpret the raw motion sensor signals.
When motion detection is enabled, the device will monitor the motion sensor to
detect when the device is in motion. To detect the start of motion, an algorithm
involving the motion detection windows is used. This algorithm declares motion
detected when a certain number of contiguous windows are each satisfied by a
minimum number of pulses from the motion sensor. Figure 76 below is an example
of Motion detection with the Window Count configured to three, Window Duration
