We are now full-timing in a stationary scenario for a while, and I am used to having a home security system in my S&B. So, after much research, we added a security system to the coach. It is completely wireless (base station plugs into outlet but has battery backup), and it is professionally monitored. They have options to include sensors for doors/windows, motion detection, glass breakage, freeze warning, water detection, smoke and CO detectors. The system will alert me via text/email each time the system is armed/disarmed or an event occurs, and I can check the coach temperature remotely. The only drawback currently is that they do not have cameras as an option, but say they are coming soon. We have not had it a month yet, but I am very happy with the purchase. I do have to pay a monitoring fee, but since monitored security is something we've always had, so it's not a new expense. There is no long term contract, and I can cancel/change my service at any time. If we move the coach, we just alert the monitoring station of our new location.
Why have this? Well, as we all know, many things can happen while you're away from home, even just to the store. Compartment break-ins, water leaks, fire, etc. So, this gives me a tool to "keep tabs" on things while we are away. It also can be "armed" while you are home.
