Wireless/Cellular | Monitoring
Alarm monitoring can work in a number of ways. Cellular monitoring, which is also known as "wireless monitoring" is the most reliable kind of communication. It uses cellular towers to communicate in the same way that a cell phone uses cell towers. These towers are reliable, and the service that is provided by them is nearly impossible to disrupt.
WIFI or IP monitoring is another form of wireless communication that alarm and other systems use. While a bit faster than cellular, systems relying on IP monitoring are as reliable as the local internet connection. This connection, while generally reliable, is nowhere near as difficult to disrupt or as reliable as the cellular communications. For this reason, we recommend a hybrid system. A system that relies both on WIFI and cellular wireless monitoring is known as a dual path system. This is the most reliable form of communication. It relies on the speedy sending of messages that the WIFI mode of communication ensures, but backs up to the cellular communication in case the WIFI or IP connection is not working.
Old systems have always relied on phone lines. Modern phone systems, however, are nearly all Voice Over IP (VOIP). While convenient and significantly cheaper than the reliable, analog copper wires of the past (which are fading out and becoming very expensive), VOIP is not ideal for security systems. The reliability of VOIP makes it a poor choice for modern systems. And its reliance on the local IP network as well as a number of digital switches on the way from wherever the panel is to wherever the signal is going makes it the least reliable form of communication. It is necessarily less reliable than even the IP communication.
Not only is cellular or wireless communications more reliable, it will also save you money on your phone bill.
