Keep in mind with the cheap X10 cameras and most webbased camera setups. What you see the whole world will see.
Especially with those X10cameras.
Wireless cameras are nice but don't put them anywhere you don't want the public to see.
One of the new angles I've read that thiefs are using. Is to drive around scanning for wireless cameras.
Often rather than offering a view for the owner. It offers a sneak peek for an intruder.
i.e. I would not put a cheap wireless camera in my gun room for all the world to see what I own.
It may just do the exact opposite of what your trying to accomplish.
I'd reccomend doing a serious security setup entirely wired. Yeah its a big pain in the arse.. but its better than offerning an advantage to a future thief.
The only wireless cameras I'd use are out in the yard, like behind a garage etc.
