When I bought my first house in Cleveland I was living alone. I had the choice between buying a dog or getting an alarm system. I chose to get Brinks put into my new home.
I was fortunate enough to get free installation (a $99.99 value) of the two keypads and the monitor system in my house. It was installed in less then a day and I felt like I could finally sleep a t night.
Brinks gave me a lovely little yard sign and more "Protected by Brinks" stickers for windows then I would ever need to use.
The security system also came with a feature called glass break. If a window shatters, even if no one enters the house, the security system goes off. This feature is great, but if you have cats like I do, you might want to disable it. I actually ended up getting a call that my alarm was going off in the middle of the night. i was so very frightened, and it turned out just to be my cat knocking down and shattering a glass vase in the kitchen.
I found the price for piece of mind well worth it. I would highly recommend getting a Brinks system in your home if you live by yourself. Just think twice about the glass break feature if your pets like to knock things over.
