You need software that allows the feed to be accessible online.
There are multiple options for this. Do some Googling.
You need to setup a server in your house that you can connect to from work. There's lots of webcam streaming software out there that will do this for you. As DP says, Google it up.
If you just want still snapshots every minute or so, I use a great piece of software called fwink that uploads to an ftp location on the web and you can pull it up in your browser. You need to have a web site you can ftp to in order to use it.
Try remote desktop with WWW active. Then you'll have access to everything on the home PC as well.
Hahaha..I actually wrote a Centrafuse plugin for a friend with the exact same requirement. He was using MS media server to stream the webcam so he could keep an eye on his dogs.
Like Curiosity said, using Remote desktop is probably the fastest and easiest.
NoMachine is your friend.

If yall havent figured out yet I dont know networking at all.
Just make sure you add a remote shock collar so you can blast him if he gets outta line!

I use my iphone to do this and there are several apps to do it and I have tried most of them and the best I have found is iCam. It records to your hd on motion and streams live. Many options available and it will even send push notifications to you iphone if you want. It will support multiple cameras hooked up to different pcs also. It has a java based web interface also if you do not have an iphone. The server portion of the app for the PC is free. The app for the iphone is a couple of bucks but if you only use the web interface then there is no need to buy iphone app. It has worked flawlessly for us to watch our dogs and elderly family members when we are not home.
