Telular Telguard TG-1B Primary Residential Alarm Communicator Bundle

To be honest, this is one of those products that just silently goes about it's job. It is mounted in the laundry room and sends signals via a cellular network to our alarm company. Our installer tested it and it was working fine. We will test it periodically, but so far we have only had it a month and a half, so I just have to trust it's quality. I do like the fact that since the signal is cellular a "bad guy" can't cut the land line and disable the alarm.
