Sampling period length

1	tte_samp_per(deploy, lps)

`deploy`	deploy object
`lps`	movement speed in length units (same as camera area measurement) per second

The average length of time, in seconds, needed to cross a camera viewshed

This function only calculates a rough estimate of the time needed to move across a camera. There may be better ways.
