More than 100 participants tuned in over the Internet toSDM’s first Webinar, “VoIP and Alarm Monitoring: What You Need to Know,” held on June 14.SDM’s contributing technology writer Dave Engebretson presented information crucial to participants about the transition that is occurring to voice over Internet protocol (VoIP) phone service and how it is affecting alarm transmissions.

Engebretson thoroughly explained how VoIP works and how the telephone and cable companies and independent providers are implementing it. The difference between facilities-based and non-facilities-based VoIP was clarified, along with packet cable standards, protocols, VoIP growth and additional sources of information.

He explained why many alarm systems do not work with certain forms of VoIP and what security dealers, systems integrators and central stations can do to inform their customers of the problem and overcome it.

A detailed slide program could be viewed by participants as they listened to Engebretson’s presentation through the audio capabilities of their computers.SDM’s publisher, Mark McCourt, presented questions to Engebretson which were submitted live during the Webinar in a question-and-answer session that followed the presentation.
