Reolink already can send push notifications for doorbell presses, I would also appreciate if they can send a still image of who is at the door as well, as it would be handy to see on my watch or phone notification.

I tried Pushover, but it was far too slow to be useful. Reolink push notifications are quicker, and snapshots can be saved on the device, maybe only allow such an option when an sdCard is in use?
