I would like to keep the inside of the house ascetically appealing but still have the ability to record in the even the home is broken into.
I sometimes setup my IP camera when we are out-of-town. IP cameras with built-in Web servers are the easiest way to check-in on the house when not at home. And many IP cameras also have built in motion detection and email abilities as well. I really like emailed images and alerts. Someday (soon I hope) the email alerts and images will be directly to my phone.
Of course all this can be done very inexpensively using all X10 products and a half decent home PC.. as well. You can get very advanced with an X10 setup by adding the Active Home Pro (AHP) software suite (and the CM15A).
There are vast amounts of info everywhere about camera setups. But the best way to learn about cameras... IMHO.. is to own one. I generally recommend "buy a one camera deal" (from X10's deals) and test (and play with) it. You'll learn a bunch more about security cameras... and ultimately I think you'll be happier with your finshed project.
Keep reading (and searching) here at the forums. As well as asking questions. But
I think.. getting your toes wet with a single camera... is much better than just jumping in.
