December 24th, 1980 a burglary took place at 96 Midwood Ave. Nesconset. This was the home of the Merz family. Donald Merz had presently purchased the home three months prior. Due to this robbery everything was taken from expensive jewelry to priceless meaningful possessions. The place had been trashed. At that time Donald Merz age 29 worked for AT&T in Manhattan as an installer. Since everything was taken in the robbery and all the money he had saved was used to purchased the home; He decided to install a security system himself in attempt to prevent a tragedy like this from happening again. At that time electronic security systems were a new thing. Through word of mouth people on the block neighbors had began asking him if he could install a security system for their home. And at that point MIDWOOD SECURITY SYSTEMS was born. Along with that he continued his job at AT&T. Over the course of ten years as a side business Midwood Security Systems began to grow to servicing over 1000 clients and building and excellent reputation. The family and office had grown as well. In 1992 Midwood Security moved to the East Setauket area.  

Unexpectedly In 2002 another tragedy occurred. Donald Merz passed away at the age of 53 from a massive heart attack. Leaving behind his business and his legacy. The business was then divided between his sons whom worked for the family business from the age of 15 as technicians.
