Question DetailsAsked on 11/29/2011

I am considering purchasing an alarm system and was told that I no longer need a regular telephone line for my alarm panel to communicate.

Do you have the same question? Follow this Question

This is correct.

Some alarms can be installed that use wireless / cell tower signal.

The concern with these systems (as we learned with our system with ADT) is when the signal is lost, the alarm automatically will go off at full alert. So depending on where your cell tower is located, and clear line of sight/trees, etc. you may lose signal. We live in the City with the cell tower almost visible from our house, yet on really bad stormy nights or when they do service to the Cell tower (which always seems to be at 3am) your alarm may sound a false alert.

Another thing to consider as you have your alarm installed; ensure you have a display panel somewhere near your bedroom. We made the mistake of just having one panel in the kitchen, so when the alarm does trip we have to walk through the entire house to find out what set the alarm off. That is a long walk when you don't know if someone has broken in or not!

Good luck!

Use of landlines for alarm system monitoring is decreasing and acceptance of cellular is rising. The fact that landline only homes dropped from 34.4% in 2005 to 12.9% in the first half of 2010 according to the Department of Health and Human Services, is testimony to advances in technology and reliability. In Spring 2010 many homes in Edina MN were broken into after crooks cut the phone lines, thus disabling the alarm system.

Signaling strength for cellular transmitted alarm systems is occasionally an issue that can be addressed with knowledgeable installation help to properly place the signaling device. However, the alarm monitoring network of Honeywell is built on the backbone of an established cellular network with redundancy built in to give added protection. Dual signaling technologies– SMS and GPRS – are available to carry the alarm communications for both alarm notification and for check-in of system status. By using paths on a cellular network that is well established, there is no fear of losing security monitoring from a cut line or a power outage as there is built in battery backup. In addition to being wireless as an alternative to a land line, wireless sensors, key fobs and additional controls within the house provide great reliability and avoid the intrusiveness of wires and holes in the wall.

Go ahead with the wireless system from a knowledgeable installation company.

I wanted to chime in here because I see that it has been since 2011 since it was answered. The wireless technology in alarm systems have come a long way, along with the overall cell reception is most areas. Most of the leading home alarm companies are now actively promoting technology that no longer depends on phone lines. Phone lines can be cut, whereas cellular technology can not be. This goes along the lines of completely wireless systems that have battery backup, so no lines can be cut.
