I have four blink outdoor cameras. Two in front and two in the back I’ve personally noticed that there are times where somebody is walking past the front of my house and the camera doesn’t catch it. This has happened more than once one occasion. The batteries are only a few weeks old. And I unplug the sync module once a day. Another problem I’m having is that when I’m playing on my phone and I receive an alert when I go to the app it takes 30 seconds to a minute for that clip to be shown. I don’t know why it doesn’t show right away, but it’s annoying. Does anybody else have any issues with these problems and anybody have any answers as to why it’s happening?
