This kit comes with 1 L7000 wireless security system, 3 5811 door and window sensors, 1 5800PIR-RES pet-immune, infra-red motion sensor, 1 5834-4 key fob, 1 3GL which is a wireless cellular (GSM) communicator, and an L5100-WIFI which is a wireless IP communicator. The combination of these communicators gives this installation dual path capabilities - this redundancy allows the systems to use both IP and GSM for those looking for the most security out of their system. For those doing a DIY installation, the LT-Cable will make installation much easier.
While the 3G cellular communication path is regarded as the most secure, there is no beating the redundant communication provided by adding both a cellular and an IP communicator to a system. For those who want the most reliable system on the market, this system comes complete with two different communicators in case the other pathway goes down.
