  Determine what your service needs will be and compare the features offered by the different companies. Do you need basic coverage or will you need an extra service that only certain companies can provide? Will the alarm company hook up the alarm through a cell phone connection, a land line or broadband Internet? Do they take safeguards to ensure that your signal will not be lost, even in a power outage?
