If you’re okay with Google GenAI to analyze your images you could try this blueprint:
Camera Snapshot, AI & Notification on Motion
Here’s the community post that goes with it:
Generative AI camera snapshot notification - Blueprints Exchange - Home Assistant Community
I feed my driveway camera images into it for some fun and the description normally comes back with e.g. the color and the model of the car that’s driving on my property.
Asking the right question, I can easily imagine that you can get a response back, if/in case the motion that triggered the images to be analyzed actually shows a crane - it requires a (movement) trigger of some sort, though.
Beware of this annoying issue, though:
