SilentKnight IP Alarm System Resiliency on Disaster Recovery and ISP changes - Manual (Page 3)

Overview
Several IP Alarm providers have claimed for DNS-based
1 solutions as the unique means for overcoming
the typical challenges identified in a commercial IP Alarm Monitoring service:
• In order to benefit from the most competitive rates, the CMS may need to change its Internet
Service Provider to a new one. This change should be carried out with little effort in the CMS and
should not imply manual reprogramming of the IP Communicator units.
• During disasters, the IP Communicators should switch to an alternative CMS automatically.
• IP Communicators on Alarm Panels should not be locked to a specific CMS. In other words,
changing the IP Communicators to a new commercial CMS should not imply manual
reprogramming of the units on the field.
Although the DNS gives an answer to these challenges, it suffers from severe limitations that may put the
IP Alarm Monitoring Service into jeopardy. As such, the FireLite IP Alarm System uses an alternative
approach which not only gives an answer to these challenges, but also does not suffer from the inherent
limitations of the DNS service.
1 DNS: Domain Name System. Among other services, the DNS public service translates the DNS name of a
given IP machine into its IP address, so it can be contacted from any host on the Internet.
