Our Passion Is Your Safety

You are at the home of the top rated fire and security system company in Suffolk County. We specialize in medium to large commercial, industrial and retail businesses. In addition, we also serve the needs of security-conscious homeowners. Our guaranteed products and services include burglar alarms, fire alarms, closed circuit television, and state-of-the-art 24HR central station monitoring.

I would like to take this opportunity to introduce myself to you. My name is Thomas G. Parente and I am the owner and President of Diamond Security Inc.
I have been operating in the Fire and Security business for fifteen years. During this time my company has experienced substantial growth and recognition amongst our peers. We have bonded strong relationships throughout Suffolk and Nassau counties with the individuals and municipalities responsible for the approvals and enforcement of local and state laws. We have gained the trust and respect of these individuals by having an open and honest work ethic governing all our installations, always striving to do better and going the extra mile to complete a project.
I've come to realize that the most important aspect of business is dependability, service and follow through. You will always be able to contact myself or a trained member of my staff 24 hours a day, 7 days a week, concerning service or even just a question.
If you have any questions, please feel free to contact me at the number provided.
I look forward to working with you on your Fire and Security needs.
