"New Tech Security Systems installed a surveillance system in our dental laboratory, consisting of 27 cameras and a 32 channel NVR capable of recording 15-20 days of activity. I am totally and completely satisfied with the quality of work performed by New Tech. From the initial project thru implementation and testing, the owner of New Tech, Mr. Albert Wainer, was personally involved in order to make sure that everything went smoothly and according to schedule. Work was completed quickly, efficiently, and without interference in the normal day to day activities of the lab. After the installation was completed, the lab was left in impeccable condition.

"Fishing cable and data wiring in a single level home (I thought) was easy to do. This company demonstrated the level of effort involved in wiring our home, which was far beyond my capabilities. Manhors involved (three persons) to install a Structured Design System, fish and install cable (Spectrum cable) and data (Ethernet) was approximately 45 manhours over three days. If you need someone to do the job correctly, to provide you great value for the cost involved, to improve your home's internet security (via ethernet cable throughout the home), and a clean safe central location to house and control your connections, give Diversified a call. Mr. Jose Cosio is a professional, soft spoken, but highly knowledgeable individual, who will listen carefully to your needs, desires, dreams, draw out a simple plan, acquire the right parts and supplies, and professionally install and set up a large or small system in you home, to ensure your home is working smoothly and securely. I will invite him back to complete future projects."
