Cellular monitoring vs internet monitoring

Several clients are asking whether we can provide alarm system with internet connection or not. It's simple to add this feature to alarm panel, but unfortunately internet connection for alarm monitoring is vulnerable technology. 

By using a pair of wire cutter, you can cut the internet cable in ten seconds. More over, the internet connection will lose once you lose power. When power failure, your alarm system may work with its internal backup battery, but the alarm signal can not transmit to home owner or alarm central station with reason of internet modem is OFF. By the way, sometimes internet service may go down, and modems and routers need to be reset for internet connection. All these case against internet monitoring.
