Testing People Traffic Counts

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?

Have not done this, however I suppose if the amount of traffic is reasonable, one could take the time (maybe increase video playback speed to 4x) and count them manually, and compare the results with the automated system.

Re: Testing People Traffic Counts

I have a customer that does this.  They haven't reported any issues.

Re: Testing People Traffic Counts

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.

That is a great idea, thank you Nolan!

Phillip, did you mean your customer uses MVs to count traffic, or that they have done a test to verify the traffic counts? Thanks for taking the time to reply!

Don, 

thank you for taking the time to reply.  How did you know that the count was on the high side?  What were you comparing it to?

Re: Testing People Traffic Counts

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.

Re: Testing People Traffic Counts

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?

Re: Testing People Traffic Counts

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.

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.

Re: Testing People Traffic Counts

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).

Kind of a big deal

Re: Testing People Traffic Counts

The cameras count everybody walking through the frame.

 

So if your entry is also your exit you'll need to halve the number.
