Software for counting visitors
I have some consumer-grade video surveillance cameras at my business (3), and I am looking to use their data to get statistics on visitor frequency and duration. The cameras are motion-activated and detect persons. I don't need to know anything about the particular individuals, just 'how many people are visiting per day/month/year, the busiest times, and how long does the typical visitor stick around.' Since this is for my company's research, I am wary of services that would use my data for other purposes other than our research. Any suggestions?
