We’re currently experimenting/piloting with RPis, the RPi camera module, and this code:
It’s working, generally, but it does require a good bit of config tweaking to get it to accurately count. It also needs (I’ve discovered) a certain amount of distance between the door and the camera. We have very low ceilings at our doorways and a single person can span the entire frame which appears to confuse the software. All that being said, it’s very much worth looking into.
Analytics out of the box aren’t great. The only built in report is only the current day’s numbers, but it’s pretty easy to export data. We have Libinsight from Springshare and I’m working on pumping that data into their system. It is tricky because the system basically records two things: a timestamp, and a positive or negative integer depending on whether or not the traffic was going in or out. By default, no generic analytics system seems to understand that well enough to display it the way I’d like, so I may have to create some custom reports using d3.js or similar.
I’m using the Pi 2 and standard camera module from Adafruit. I’d be happy to answer questions.
