Having previously using LJS Systems on my own property, I felt comfortable to recommend them to my parents to install a new CCTV & intruder system. They were very polite and made my parents feel completely comfortable during the work and even took the time to sit down and show them how the system works. Very happy and would recommend to anyone.
