The easy answer is no, most alarm systems do not require a phone line. With Honeywell’s security panels, Alarmnet allows for wireless communications via the internet or the cell phone network. For DSC alarm panels, the answer is Alarm.com. Both of these technologies allow for an alarm system to communicate without a home phone line, everything is done wirelessly. More and more home owners are cancelling their home phone services, which makes wireless communications a must for alarm panels. We have priced our wireless monitoring rates so competitively, that 95% of our new installations are all wireless systems. Honeywell’s older alarm panels can also be retrofitted to wireless communications. If you have an older alarm panel that you want to get monitored, ask us about our takeover deals.
