Samsung has just come out with a lot of whole home solutions. A Camera is just one of them.
This is if you are looking at expanding in the future as well. Cause I will admit it is a little expensive, however it is geared towards growing the things in your home.
Start here Samsung SmartThings | Smart Home Automation Systems & Products
Then if you scroll down towards the bottom, there is a "create your smart home" link. You will see the monitor you pet option which was designed by a certain someone, to monitor a certain special pet, you know I can't name names or anything.
Then future add ons, which you can add later much cheaper, smoke detectors and water leak detectors. But more in the pet line, which there should be more pet packs added to this include the outlet, you know so you can remotely turn the fan on for your pet when you see them getting warm. Also there are a huge line of door locks, and door knobs that already work with this so you can remotely lock and unlock or assign unique codes to for one time use remotely. They have some cool features like detect your phone as you approach from walking the pooch and unlock automatically or open the garage door. However you have them set up.
I have seen the whole set up with camera and so on cheaper at Costco as well.
Edited to add this link, here is products for home including the door locks, and entranceways, speakers and intercoms, you can let the UPS man into the Garage remotely etc. There are a ton of better looking ones coming as well that all build off the initial hub.
