security when we're at home with crank windows

Hi,

My husband and I are strongly considering getting Simplisafe, but I have a few questions that hopefully someone can answer for me.

The main reason we want Simplisafe is to protect my kids and myself in our home (both at night and in the day) when my husband is not home. So, although motion detectors would be great for when we're not home, they wouldn't be something I'd want to use when we're home because (1) we'd be constantly setting them off, especially considering that I have 2 small kids who don't sleep through the night, and (2) we want to prevent someone from entering our house by setting off an alarm as they're trying to enter rather than just alerting us that someone has already entered the house (as a motion sensor would do).

We live in a modest ranch house with a large basement. All of the windows on the main level are crank windows that open from the center outwards, and we have a large egress window in the basement that also opens with a crank nob. However, the rest of our basement windows are all the smallish windows that slide open from the middle to the side (thus, only half of the window is actually open at a time).

Anyway, I'm wondering if the SimpliSafe entry sensors would adequately alert us if someone were to try to gain entry to our house through a window. The reason I'm confused is that I don't understand the way burglars would enter a crank window or sliding basement windows. Would they pry open a crank window?...or just break the glass? Would they remove the entire basement window? I guess I'm confused about that, so I'm not really sure where on the windows we would mount the sensors. Could you help explain to me if SimpliSafe is a good option for our windows and also tell me how to mount the sensors?

Thanks so much!
