When you're walking out the door for a vacation or even just a normal workday, it's easy to be thinking about what's ahead, not what you're leaving behind. Sure, you locked the doors, but what if you want to check up on your home while you're gone?
Most people don't think about setting up a monitoring system until they're already out of the house.
An internet-enabled security camera will do the trick, but most people don't bother buying and installing one, even though I recommend it. Take a look at some of the great security cameras available in my store.
If cost or complexity is holding you back, I have a less-expensive solution. You probably have a webcam for your desktop or laptop computer, which means you already have almost everything you need for serious spy-grade home surveillance (when you and Fido simply can't be there to secure the home front "old school" style).
