This business installed a Ness security system in my house. The system is excellent quality and there have been no malfunctions or false alarms. The installers did a great job and left no mess. I did contact this business recently to have one additional detector installed but the price was ridiculously high compared to the initial cost of the system so I didn't proceed.

Approximate cost: $1,500
