Monitoring Distance Range

Electric lens is adopted for the positioning system's thermal channel. It supports auto-focus and remote
focus. For different lens focal length, the monitoring range is shown in the table below:
Table 3-1 Monitoring Range (Pixel Interval: 17 um)

NOTE: This table is for reference only, and the actual detection range may vary according to
different camera settings, mounting condition, monitor, etc.
When the weather is fine and the atmospheric visibility is normal, the probability of
detecting/recognizing/identifying target is 50%.
The human width is presumed as 0.5 m (human width cannot exceed 0.75 m), the human height is presumed
as 1.8 m, and vehicle width cannot exceed 2.3 m.
