We got this to monitor our dogs while we're out. We have 3 - a 5 mos puppy, a 1-year-old Cattle Dog, and a 2.5-year-old Alaskan Malamute. They're rambunctious when we're around, so we could only imagine before what it was like when we weren't around. Now we don't have that problem.Not only can we see them, but we can hear them, too. Even better, they can hear us. Now our goal is to get them to respond to our voices through the camera as if we were there!It's controlled completely by our phones, and after the initial setup with an ethernet cable, we've been able to move it around the house depending on where we lock the dogs away before we leave. There have been no connection problems, sound problems, or video problems! I'm definitely going to be picking up some more of these cameras to have in the house so we can leave the dogs out to roam the house.
