Can I remotely access a web cam?

Hello, my question is in regards to web cams. I currently have one set up on my laptop, and I am wondering if there is any possibility of accessing it remotely? I know there are concerns with viruses and their ability to do this, but I am just looking for a way to see my home for security while I am away. I'm not looking for anything fancy, just an ability to access it. Thank you.
