How to custom a device and entity to xiaomi camera

[MDP1997]

Hi, i have a xioami c301 camera, and i want the camera to take the fav-zones but cant get the attribute

I saw in https://home.miot-spec.com/spec/mxiang.camera.c301 the properties of the camera but dont get how to integrate it

I tried here but dont get how it works

[al-one]

number_properties: image_rollover,alarm_interval,active_fav_area

The - in miot property names needs to be replaced with _

Thaks you so much, it worked perfectly
