Automatic Image Refresh
Roadside camera images in Vizzion's roadside and on-vehicle camera API update at a regular interval. This interval, in milliseconds, is stored in the UpdateFrequency field for each camera (see GetCamerasInBox). It is recommended to automatically refresh a camera image at the rate given by this field. For example, if a camera has an UpdateFrequency value of 2000, the image should automatically refresh every 2 seconds.
Note: Hotspot cameras will not provide an updated image more often than every 5 minutes, so it is recommended to automatically refresh hotspot camera images every 5 minutes.
