Can I ask how does your "Dogcam" work, how much does it cost and where can I get one?
My dog is home alone during the day while I'm at work and she's a known escape artist. I'm yet to figure out how she does it! Last time she escaped she got caught by the cops!
I have several cameras at home. Some are a basic security camera arrangement, like you see in shops:

But this is not usually directed at the dogs. For that I just use wireless IP cameras like this one (I use another more expensive model but they getting quite cheap now)

They are on my wifi network at home and by using "port redirection" I allow them to be seen from outside my home via passwords. You can just use a normal web browser to view but I wrote a monitor program (DogCam) for windows and for Android to watch and save the images. I just use still images every 20 sec or so, no need for video. When I see the dogs start to jump up and down then I can check who is outside using the security video. I guess my two dogs are part of the home security too
I'm lucky in that they choose to sleep by the front door most of the day, so I aim a camera there. I put a few more around the house but I can't cover it all of course so sometimes I can't see where they are.
