Centroid FAQ

Installation

1. Centroid wifi SSID is not able to be found on mobile devices.
   1. Make sure the wifi dongle is plugged in firmly. Try rebooting Centroid.
2. Do not know the RTSP URL of their CCTV or IP camera.
   1. Look at https://www.footfallcam.com/people-counting/knowledge-base/chapter-3-centroid-configuration/#3-3-2-cctv-default-relative-url to see if the existing camera brand is on the list.
   2. If not in the camera brand list, kindly refer to the camera vendor, or try to look it up on the internet.
3. What happens after the installation?
   1. Similar to counter, Centroid also requires tuning and verification based on video recordings. 
   2. The tuning process takes 3 - 5 working days, depending on the number of cameras bound.
   3. After tuning, Centroid will then start counting data.
4. Can the wifi dongle be unplugged after the installation?
   1. Not an issue, the wifi dongle is not used for any counting or wifi analytics purposes. However, if the installer were to revisit the centroid due to misconfiguration or other issues, they must bring the dongle.
   2. Generally, we recommend leaving the wifi dongle plugged in.

Counting Data

1. Where can the end user see Centroid data?
   1. Behind the scenes, Centroid is using Pulsar to upload data. Hence, data is only available in Custom Report tab in Portal.
   2. It is not available in Analytics Center, Heatmap Report, or any other place. Those are for counter's data.
2. What data is available?
   1. In/Out counting data and occupancy data are readily available.
   2. Demographic analysis, vehicle type detection, heatmap data, etc are still work in progress.

Camera Model Compatibility

1. How to verify if a camera model is compatible with centroid?
   1. Get the exact full camera model, for example, Hikvision camera model DS-2CD3343G0-I
   2. Google the exact model and obtain the spec sheet. Check if it supports RTSP protocol, for example
      Hikvision: https://prnt.sc/1upuplj
      Axis: https://prnt.sc/1upv3iw
      Dahua: https://prnt.sc/1upv7h4 
   3. Check that camera lens do not have significant distortion. We do not support 360-degree panoramic view, wide angle lenses, or fish eye lens. There are 2 ways to check:
      1. Search the exact model on youtube, and check the live view from demo/unboxing videos.
         1. OK
            
         2. NO fisheye lens (because of circular distortion)
            
         3. NO wide angle or panoramic lens (because of distortion at 2 sides, and unusual aspect ratio, width >> height)
            
         4. Or, check the horizontal FOV (field of view) in the spec sheet. Must be 30 - 120 degrees.
