I finally added my Intelbras Mibo IC3 camera to Home Assistant.
I used the ffmpeg platform.
camera:
- platform: ffmpeg
input: rtsp://admin:AAAAAA@192.168.xxx.yyy/live/mpeg4
name: office_cam
The password (AAAAAA) is located under the camera, next to the QRCode.
After testing the config and restarting, I added the PICTURE ENTITY card:
entity: camera.office_cam
type: picture-entity
I help this will help others in the future.
