I want to change the highlight color of the hot zone with SDK

For the map, you can set a hot zone (area for transition to another map). And, as a function of the COTS standard hot zone, the hot zone changes color according to the status of the camera in another map.

Is it possible to change this hot zone to highlighted color in SDK? (For example, changing the color of the hot zone to an arbitrary color)

As an operation, when alarms are raised in multiple hot zones, coloring each hot zone, for example, red and green, and attaching a red frame and a green frame to the frame of the corresponding camera image This is because it is assumed that the user’s visibility is improved.

If it is not possible to change the color of the hot zone with the SDK, as an alternative, is it possible to realize the same function in other ways with the SDK?

It is not possible to modify the color of a hot zone.

You can have your own MIP item and control what icon should be shown, and change it when needed. (For Map - not SmartMap) - the SensorMonitor sample show how.

Try this: In the map in setup right-click, in the menu choose Status Visualization. (Nothing you can do in a MIP plugin). I hope it fits what you try to configure..
