Re: Security System and self monitoring

["Jackcsg" <nospam@xxxxxxxxxx>]

There are several different grades of Internet service. They range from
aDSL, cable modems, and satellite. They offer NO guarantee of up time, hence
the low cost. sDSL, T-1, and other fractional T services offer guaranteed up
time, typically 99.99 percent. Unless you're dependant on running your
business out of your home, typically, you choose the cheapest service you
can find. Where a business, typically, chooses the higher dependability of
services.
Of course nothing, including anything you own electronic, is guaranteed to
work all the time.
It's knowing when it doesn't that makes the Internet a better choice for
routing alarm signals, and either radio back-up, or cellular back-up, that
further ensures communication.
People who choose to cancel land lines, and place a VoIP service as their
only form of communication to the outside world, aren't very smart. There
isn't a single business in the US that operates with that kind of mentality.
VoIP is a product designed to cut communication costs, not replace them. The
reliability just isn't there yet, residentially.
