Don't be held hostage by the cable company or an alarm company who puts in equipment that
can only be monitored and serviced by them, then raises your rates or charges you for an
expensive service contract. We use NONPROPRIETARY equipment, so you can change alarm companies without changing all your equipment. (You'll stay with us because you love our
service and rates).
