Home Alarm Systems & VoIP

Can a Home Alarm System work over VoIP? If so, how? My home's alarm
system is monitored by a company that requires phone connection. I've
been attempting to come up with a solution, but without success. Any
assistance you can provide would be appreciated!

Thanks in advance!

Systems that place a phone call can work over VOIP (pretty obvious) but
other systems that test the phone LINE (wire continuity) will not (also
obvious because the phone wire is not in use).

 

An alarm system working over VOIP is a very hit and miss thing. The
combination of the various alarm protocols (4x2, Contact Id, SIA)
combined with the inherent problems of VOIP(latency, compression) are
causing many problems for alarm monitoring stations. You will find very
few monitoring stations that will guaranty alarm devery over VOIP.

Having said that many of the newer alarm systems from most of the
manufacturors have TCP/IP addons and the more progresssive monitoring
stations will be equipped to handle this.

 

Theoretically it can work, assuming that the power is on, that your
Internet connection is active, etc.

Problem is that VoIP circuits do not have the track record of POTS lines
yet. What if there were a real emergency, such as a fire, and your
power lines were out? What if your Internet connection was experiencing
temporary down time?

The most secure type of phone connection is called "Derived Channel,"
and is a supervised connection. I do not know if the service is still
offered, because it involves piggybacking a signal on top of one's phone
line. The phone company thus knows if the line is cut, and can notify
the alarm monitoring station of a possible problem.

Burglars often would cut the phone line before breaking into a home,
thus making it impossible for the alarm systems to report to the central
station.

I know of some alarm manufacturers that offered a cellular backup. The
alarm would first try to dial out on the POTS line, and would use the
cell as a backup. Unfortunately, the subscriber had to pay a monthly
cell bill, and the cell service was virtually never used.

The best circuits are called McCullough Loops, which are supervised
24/7. Underwriters Labs certifies these for banks, jewelry stores and
other critical applications, where there must be assurance that the line
is working.

FOR THE MONEY your best bet is to keep the alarm hooked into a regular
POTS line right now. It may be relatively primitive, but POTS lines
have the best overall reliability record, over cellular and VoIP. If
you can accept the higher risk associated with a VoIP connection with
your alarm company, you might save a few bucks, but how much would it
cost if you kept a POTS line, dumned down to only the most basic
service, used only for the alarm? In an emergency, it could also be
used if your VoIP line went down.

 

I appreciate your time and full analysis. This is good info. Just
wanted to also let you know that since my recent addition of fiber to
the house Verizon has already connected by POTS line to the same
terminal as my computer, etc. Everything goes through the fiber now.
That being said, I'm sure some conversion takes place before it's
converted over to fiber connection. Basically, Verizon took a pair of
copper wires, ran from the fiber terminal over to the POTS terminal and
that's how I remain on my "same" phone.

it just seems odd for me to pay $50/month for a copper phone line that
actually goes through my fiber line anyway. I may actually contact the
company that monitor's my alarm system to see if they have any IP type
system that might work.

The battery backup system will work for "a while" with the fiber, but
eventually turns it off so phone over fiber can be used for 911, etc.
The battery backup unit does have a terminal for a secondary power
source. I may actually find a way to use a real UPS to provide the
"long term" backup solution for that unit.

Again, this is in the future. I'm not converting this over now. Just
getting plans and knowledge so I can make an informed decision. I
certainly appreciate the time everyone has put into their responses.
VERY much good food for thought.

Take care!
