Always want to go skydiving. Would the wind hurt my cheeks from going so fast?
For large rooms, and groups of windows, get the Window Break monitor. I used one in the living room and kitchen combined, and it worked well when one of the windows got broken. Then, alarm the windows in the back, because it's easy to break in there, because no one can see you. When you alarm bedroom and bathroom windows, ask the installer to install the contacts offset by the maximum that they can be offset, so that you can open your windows a couple of inches without the alarm going off. If you don't offset them, and you want to have the window open part time, then you have to buy a whole second set of contacts and install them on the same window.
This is a bit like asking: Which is better in a car, a seat belt, or an airbag? They both provide protection, but do it in different ways. And they provide the best protection when both are used together. Alarm systems can detect an intrusion, notify the police and neighbors that an intrusion is occurring, and possibly scare the intruder off before he does much damage. Camera systems are generally used to provide documentation of what occurred after-the-fact. For example, if someone broke into your home, you could look back upon the recorded images and possibly be able to identify the thief. If properly placed, cameras can also be used while you are home to observe what is going on. In my opinion, the average homeowner would be far better off with an alarm system than a camera system. There are many sophisticated things that can be done with cameras (remote monitoring of cameras from a security station, video motion detection, etc.) but these types of things cost far more than most home owners are willing to spend.
Got slapped twice at church last night. How? It was so hot. When we stood up to sing, the woman in front of me had a wedgie, so I reached up and pulled her dress out. When I did that she slapped me. You said she slapped you twice. Well, I figured she was upset with what I did, so I tucked it back in!
