Wednesday, March 29, 2017 SEM - DIY Installation has really outdone themselves this time with the ADC-SEM100-LTE /ADC-SEM100-CDMA cellular communicators by making DIY installations a breeze. These modules are also known as the System Enhancement Modules (SEM). Previous to this module if you had a Honeywell Vista 10p, 15p, 20p or 21ip you would have to use Honeywell Total Connect services to control your system remotely with text and email notifications. Sure there have been other companies such as IP-DATA-TEL and Telular to make universal cellular communicators that allow for basic arm/disarm and notifications but, if you wanted to add z-wave home automation devices you would have to purchase an additional module for that to work. has gone above and beyond by including the Z-Wave radio inside the SEM module this saves the customer time on their DIY installation and money by not having to purchase a tuxedo touch keypad or a Vista Automation Module(VAM). The only one thing that this module is not able to handle is image sensors. If this is the case and you're looking for a video solution try IP-Cameras. The last major benefit of the SEM cellular communicator's is the fact that it can take over existing Honeywell Vista 10p systems as long as they are from 2005 and above. Once you have activated your SEM cellular communicator make sure to activate some sort of interactive alarm monitoring services. This will allow for GEOARM to remotely access your Vista security system remotely to assist you with Tech Support and programming. The System enhancement module is perfect for DIY installations.
