    Highland, MD - Checkbook Review
  • Outstanding! It was a pleasure doing business with this company. They are knowledgeable, honest, timely, and the quality of work is excellent. The pricing is provided upfront with a menu of options. The monitoring company they work with is very responsive. We accidentally opened a window and before disarming the system and got a call within seconds. By the way, they must be one of the few home security companies who does not require you to sign a monitoring contract to get a system installed. I would recommend this company without hesitation.

    Angie's List Review
  • Their price was reasonable given the cost of the system's components and the time spent installing it.  Their installation was clean, quiet, and professional -- very important given that we have a newborn at home.  They even scheduled a more convenient time to come back and test the siren.  I can't think of anything I would have wanted different about the experience.  They built a good system, installed it cleanly, and educated us on how to use it.
