voipFirst of all, VoIP stands for Voice Over Internet Protocol. This service although generally less expensive than traditional telephone company landline service is lower in voice quality and much less reliable than a conventional land line. You need to be aware that if you are considering replacing your landline with VOIP service to save a few dollars per month, your existing alarm’s system will no longer be able to communicate with your monitoring station unless you have had a cellular or radio back up module installed in your security alarm master control panel. You also must subscribe to a digital cellular monitoring service from your provider as well. Unfortunately, many of the VOIP service providers do not disclose this major drawback to their customers in their advertising, marketing, and sales literature. Their customers find out after they make the switch to VOIP that they are totally unprotected because their alarm systems will no longer transmit signals to their monitoring station. Some of the more reputable VoIP providers do warn their customers now to keep a conventional land line if they own a security alarm system. There is also module now available that can be purchased from most competent security dealers that can be installed in your security panel that will allow your panel to communicate with the monitoring station using VoIP service. However, this module is expensive and you are still vulnerable to internet connection outages, viruses, and power failure which would render your computer and VoIP service useless. We recommend that if you must have VoIP Service that you subscribe to ADT’s Security Link digital cell backup monitoring service for only a few dollars more per month. With this added service you have the ultimate in security protection. In any event, whether you have a loss of phone service, someone cuts your phone line, or you suffer a power outage, the signal is transmitted over the air waves wirelessly (just like your cell phone) should you have an alarm event.
