I got my first alert from Arlo camera today. I was expecting it as the owner of the place is letting an electrician into my unit to install a 50 amp plug. So I got the alert and was able to open the camera and see it was the electrician. Another thing it did that I didn't realize it was going to do, was the email it also sent had a very nice HD quality still photo attached of what set the alarm off. So I really didn't even need to log onto the camera I could have just opened the email and looked at the photo.
I think what I was most impressed with is the microphone on the camera. It seems to pick up everything. I can even hear the birds outside the storage unit singing!
