Alarm questions indoor/outdoor stuff

[JediSpork@xxxxxxxxx]

Hello. I just had a break in on Christmas Eve. We had a lynx setup but
only used it for the chime function or armed it on vacations. My gf
would always tell me to stop being paranoid and she didnt like to use
it so I became lazy about it also.

I just spent about 400 bucks buying extra sensors and glass breaks
(wireless). I'm also buying some of the key fob remotes because they
look so easy to use. So hopefully I can get my gf in the habit of
using the alarm. Also running another siren to draw attention away
from the panel.

They kicked in 2 doors and entered through the side of my garage. The
guy thats replacing them for me is going to setup a block with  2x4's
because they are sturdy and easy to remove. He said they would hurt
themselves trying to break through it. I'm also having a deadbolt
properly installed on my front door. I might do a contact sensor on
the main garage door if only to verify that it is closed.

How likely is it for them to break a locked window or a patio door?
I'm assuming they prefer regular doors because they make less noise
and dont have to deal with glass.  Its actually a newer home with
modern windows so I'm hoping the locks are better than old houses.

Some of my windows are about 7 feet off the ground and a person would
have to be very agile or have a ladder to get through them. These are
the ones I usually open in the summer time. If I didnt do sensors on
them I could run the alarm and still have fresh air in the house.

After the alarm is going strong I would like some outdoor deterrents.
I was thinking of motion sensors and cameras but we have a lot of deer
and rabbits going through our yard. I don't want to crap myself
because a rabbit runs through my yard and wakes me out of my sleep.

What good could a camera system do if your not watching it all the
time? It might just generate more paranoia for me checking them all
the time.

I've settled on the possibility of just doing motion lights.  I
realize most know what these are now but even I'm still startled when
I go to visit friends that have them. What do most of you pros think
of them?

I'm still real nervous about all of this happening. I no longer feel
comfortable in my own home but I'm hoping the alarm will help a little
bit. My girlfriend is taking it fairly well.

How likely would it be for them to come back? I wonder if they can
even remember the houses the've been in. They also hit a house down
the road so I'm assuming it wasn't someone I know from work or
something.

thanks for reading my long rant.
