Examples of Alarm Responses for customers on an Advanced tier.

Customers on the Advanced tier will receive comprehensive alarm responses that contain all the information from the General tier, as well as additional data fields such as object_class and object_color. These fields provide additional context and insights into the alarm event, enabling customers to quickly and effectively respond to any issues with their system.

The newly introduced object_class field provides supplementary information regarding the specific class of a vehicle that has triggered an alarm. The supported vehicle classes within our API solution include four distinct categories: "car", "truck", "bus", and "motorbike".

The recently added object_color field outlines the color of a vehicle that has triggered an alarm. Our library comprises 147 distinct colors for this purpose. The object_color value is computed for each bounding box associated with a vehicle trigger. It is important to note that factors such as varying lighting conditions and shadows may influence the accuracy of the detected color.

Below are some examples of input data and their corresponding responses with updated structure. These examples showcase the latest changes and improvements to the response format, enabling customers to better understand and utilize our API's features.
