This article will inform you what the different colours mean under each vehicle name, on the Maps tab, in your ZenduCam - Trax portal
Green: The vehicle is moving and the camera(s) is online
Yellow: The vehicle has stopped but the camera(s) is online (this usually occurs if the vehicle is idling, or a few moments after the vehicle has just been turned off)
Grey: The vehicle is turned off and the camera(s) is offline
Blue: The vehicle is moving, but the camera(s) is offline. This could be due to low connectivity in the area, or a problem.
