I have an inquiry from a sales lead about tracking the number of trucks leaving a sand pit w. loads (of sand). They might have 100 trucks/day picking up loads, and a rotating cast of independent drivers/trucks that are engaged by the facility's one primary customer.
The facility owner (my potential client), wants to have some automated means of generating a monthly report of the total number of truck loads leaving the facility. They'll be getting a report of loads from a customer or contractor but want to be able to compare that with their own internally generated tally. If there's a discrepancy, then they'd go back through the video logs to try and determine the cause of the discrepancy. They project this pit will be in operation for ~10 years, and don't want to have to pay a guard to stand out there and count trucks. Perhaps they're also concerned about the guard being bribed or somesuch to boot.
Apparently one existing method (besides LPR camera/software) is to slap a QR code on each truck, and have some reader system detect it & log that truck in a database. This isn't an area I have any familiarity with; can anyone offer any experiences with QR codes & the associated software, versus the LPR approach?
