We actually contacted them as we were interested in a new system. The guy that came to our house was knowledgable but did seem a little pushy when it came to the deal. We decided to go ahead and give it a try. We have had our system now for about a year and I must say in the beginning we were excited to have everything that we could control via the app. Things started pretty good then little by little we started having issues. Many times the back door lock would show unlocked when it in fact was locked. Then the front door.. then the video camera doorbell stopped working... then the garage door showed up when it was closed (and if you tried to close it, it was actually open the door).. what a nightmare! Then the doorbell chime would not ring correctly. They gave us a new one.. same problem! Then when you actually call for service you deal with Moni and they don't communicate with Envision.. all around a disaster! Don't waste your time with this company!
