Time Alarm installs hard wire home alarms. If you are looking for wireless, this is not the company for you. Owner Glenn Devoe installed a whole system though my whole house in only a few days. Initially there was a problem with one of my motion detectors but Glenn immediately fixed the problem. Glenn is very responsive to any questions and problems I encounter (although there have been almost no problems since my initial one). He is very competent. I would recommend him in a heartbeat.
