I thought I would start this section off since I do have a security system installed in my current trailer. I got it at lowes and consists of the IRIS hub and devices (Z-Wave). I have motion sensors, door switches, water sensor (washer pan), CO sensor, alarm siren, and wall key pad. This is then tied to a Verizon MYFI router that also serves as my PC hotspot. It works great as long as you are in reach of a cell tower. If you aren't it will only work in local mode and not be able to call you if it senses a tripped sensor. I wish I could tie the AC thermostats to the system like I was able too at my house by using nest thermostats but alas Dometic hasn't seen the light yet.
