For what it's worth, I have had ADT security on my home for years. Luckily never had any intruders but I feel like my family is safe as I'm away from home about 100 nights a year. Maybe that sign in the landscaping sends them on down the road. The sky is the limit when it comes to security. I have camera's that watch my driveway, front and back door and my shop. All I have to do is press a button and pull it up on my tv and I can see them all at one time. Like I said it doesn't come cheap but I never had to worry about my kids sneaking out or sneaking someone in....lol...
Never had many issues with the security system and when I did they were at my home instantly fixing the problem. I would never have another home with out one...I would say give them a call and see what they have to offer you.....A quote is free....
