This depends on the type of wireless home security alarm system you have installed in your home. Typically, homeowners have one of four choices when it comes to connectivity to the alarm monitoring company:
Traditional telephone lines
Voice over Internet Protocol (VoIP)
Strictly speaking, if your home security system communicates with a monitoring center via the Internet, your alarm system would no longer be connected to them, should you lose Internet connectivity for any reason.
These reasons include network outages at your ISP, a power outage, equipment failure, and deliberate outages, like prank-playing neighbor kids or even a burglar cutting the wire outside your home.
Wireless connections using VoIP technology are vulnerable to Internet outages as they draw their power from the home phone line. Some alarm companies use technology designed to maintain connectivity with the monitoring center in the event of an Internet outages when using VoIP.
Cellular radio offers the most reliability for connecting your alarm system with a monitoring company and remain unaffected if the Internet goes offline at your house. Like a cellular phone, these types of home security systems use specific radio frequencies to maintain communication with cellular transmitters in outage situations.
