BIL does security installs. He put Arlo camera's up in the house. Checking the retail prices for these I wouldn't have bought them. They are nice because they are wireless but that means having to deal with batteries and conserving battery life. So you end up turning down the quality, and not recording continuously. They also take a long time to detect motion.
They have only been up for 4 days so I haven't seen the true battery life yet.
All we really wanted was a baby camera to watch on the kid. Ended up with a whole security system ( 3 glass break sensors, 2 smoke sensors, sensors on all windows and doors, and 3 Arlo cameras) so I can't complain.
edit: the arlo camera's blow big time. The main issue is that they don't record until motion stops, they just record sessions at whatever you tell it to. The maximum you can record per session is 2 minutes then there's a long lag time to save the file and restart the next session.
