Is anyone using the MV cameras to count traffic entering a building?
If so, what did you do (if anything) to feel confident that the numbers produced by the cameras were reasonably correct?
Solved! Go to Solution.
We've found the people counting with MV to be inaccurate on the high side. The feature is still very useful to trend busy hours/days, but I wouldn't consider it accurate. In busy environments with people walking behind each other or behind obstructions, the inaccuracy increases.
Meraki does a good job of explaining the things that can throw off the count here:
We've seen the accuracy improve over subsequent releases and I fully expect it to continue to improve.
We have dedicated people counters in some of our retail stores located above the entrances and the MV counts are much higher than what the people counters are reporting.
Don, thank you again for taking the time to reply, and to send the Brickstream link. We are also considering more traditional traffic counters, so I'll look at this one.
any idea of the difference, percentage-wise, between Brickstream and Meraki?
Do you think it's because the Meraki camera does not account for directionality? Are you getting the traffic count from the dashboard, or pulling it via API?
We're just comparing to the dashboard numbers. I have not done a recent comparison. When this was first launched (maybe a year ago?, older firmware) we were seeing Meraki numbers 10 times higher than the traditional people counter.
We have seen improvement over time and our store we used for comparison was extremely busy (lots of people dwelling and moving around each other and other obstructions). This is a very difficult use case for the MV camera.
We still love the people count analytics as a comparative measure. In 3 clicks i can get to the busiest minute, in the busiest hour, on the busiest day of the month and immediately see what the store looks like at max capacity. We find that extremely valuable.
If dead accurate people counts are important to you then there are more traditional options that may be better suited.
>Phillip, did you mean your customer uses MVs to count traffic, or that they have done a test to verify the traffic counts?
They haven't done any test to verify the counts. They use them to count people both at the entrance at at various places in the stores.
Phillip, do you know how they account for directionality? or do they just take the count as-is from the APIs? because that is a count of people entering the camera's frame of view (so it wouldn't differentiate if they're going in to or out of the door).
The cameras count everybody walking through the frame.
So if your entry is also your exit you'll need to halve the number.
I'm currently trying to replace our traditional 'above the door' counters with the MV12 or MV32.
I'm trying to setup the API calls to populate our dataserver with the count.
I just want to receive the door count but I only see the MV sense API calls, so does one need the MV sense license just to be able to get this simple statistic or is there another API call I can make to get this data?
>so does one need the MV sense license just to be able to get this simple statistic
Yes. Note all orgs get 10 of these licences for free (you already have them, just need to assign them to the cameras).
