"Wanted to keep up with the new consumer trend of doorbell cameras. Got one for our front door and motion sensors for our main rooms inside. No extra fees or anything weird like that. Straightforward and honest process with this ADT dealer partner."

"We own a small family operated jewelry store and decided to get ADT for protection and surveillance. Prior, we just had Ring and it was not sufficient or reliable. This has clearer cameras and a much better app experience. Happy with our new system and equipment."

"I inquired of NEXimage about purchasing 4K television and sound bar after a long search and after having approached numerous other vendors unsuccessfully. I thought that the job might be to small for a business of this nature; however, they were very helpful offering me numerous options in a wide variety of prices. They helped me make a great choice by explaining all available options in a manner that I could easily understand. Shortly after placing the order they informed me that the equipment had arrived and they scheduled installation at my convenience. The work was completed neatly promptly. The representative explained to me how to operate the equipment and made sure that I was comfortable with using the equipment before they left. My house was left clean and they removed all waste materials. I would highly recommend NEXimage to anyone, they are a professional, courteous and knowledgeable organization which I experienced to have been priced comparatively."

"In the main, fine. Mr. Liken purchased and installed white/ivory outlets that did not match the almond colored walls and switch plates. I had to purchase almond outlets, which Mr. Likens returned to install after removing the white ones that he left me."

"Self installed is the only option. System works fine for the most part though we have had problems with the motion sensor cameras. Not that I have anything against FrontPoint, but if I were replacing system, I would probably go with Simply Safe now that they have cameras."
