Yes, you are correct… When I do this again I get the same result as you, sorry. That function need some more thinking how it really should work. I assume the idea with a rule is that you receive en email only for that cam and not for the others. It is probably also different if you have few cams like 2 or 3 or if you have 64 cams. I think that as default it should be an email notification from all cams with some pictures (as it is now) and when you create a rule it should be an email only from that cam with a picture.
