What Clients Say

This case settled “on the courthouse steps” as the saying goes. It is confidential and so I am restricted in my comments. But for your “expert” intervention, the defense “manufacturer-installer” would have escaped unscathed. With your “expert” intervention they were compelled to enter into a settlement on the day the case was set for trial. As I said above, the settlement is confidential but I can tell you this: Our client got her job (and dignity) back. It was a long road back for her from the trauma of the sexual assault. Your attention to detail made this possible. Your deposition testimony was the keystone to a very successful resolution of a very difficult case. Thanks for your help. I hope our paths cross again.

It is truly my belief that without your professional testimony this might have gone the other way. Justice has been served in this case!! On behalf of myself and my client we thank you for such competent work. I would highly recommend you in the future to clients and colleagues of mine. Not just because we were successful (although that is a plus) but because you are truly an excellent expert in that you conduct such a complete investigation and have the ability to effectively communicate your opinions. Thanks again Jeff !!!! Read More

Your input during the discovery process and your deposition testimony were critical in helping us to obtain a successful outcome for our client. It was a pleasure working with you and I hope to be able to work together again in the future. Read More

It was a pleasure meeting you on Tuesday at the ASIS Western New Jersey Chapter meeting. Your presentation was one of the best that I have heard at a Chapter meeting. Bruce Harman, a friend, and colleague of more than 40 years has heard you speak and encouraged me to attend and learn. Just in case you do not know, that is not our chapter. We attended the meeting just because Bruce wanted us to hear you speak. You did not disappoint. You lived up to everything that he said you were. I am writing to encourage you to please go through the process and complete the Call For Presentation for the 2015 Annual Seminar and Exhibits in September.

This is to certify that on March 8, 2012, Mr. Jeffrey Zwirn, President of IDS Research & Development, Inc. gave two guest lectures at John Jay College of Criminal Justice, the City University of New York. He gave a 75 minute lecture at my undergraduate course. International Criminology (SOC 341). International Criminology is a 300-level course that analyzes the nature and causation of international and transnational crime and examines issues in the globalization of crime, including terrorism, money laundering, drug trafficking, human trafficking and weapons dealing, among others. Mr. Zwirn also prepared a power point presentation and gave a 2 hour lecture at my graduate course. International Crime and Justice Theory (ICJ 700). International Crime and Justice Theory examines the multicultural nature and etiology of international and transnational crimes. The course reviews various perspectives, approaches, and theories of crime and criminality that assist in understanding the development of new forms of crimes worldwide, and in developing international crime prevention policies. The course commences with grounding in theories developed in the cultural context of the United States and expands to embrace theories from other regions of the world. Mr. Zwirn, who has been actively involved in the development, application, design, installation, testing, and inspection of thousands of burglar and fire alarm systems, gave the students a critical insight and analysis into alarm and security related issues. He elaborated on the "crime triangle" and the applicability of Rational Choice Theory in the context of burglaries and organized theft. His lectures were very informative and engaging. The students participated in a lively discussion on the importance of alarms in crime prevention policies. Mr. Zwirn prepared testing materials for the students and exhibited a high level of expertise in the subject matters taught. Read More

To Whom It May Concern: The New Jersey Burglar and Fire Alarm Association asked me to join the board as education chairman. I believe this was based upon my past experience in the field of education. I was an electronics teacher at Indian Hills High School and finished my master’s degree as a principal/superintendant. I have written many courses for Indian Hills High School that were approved by the NJ Board of Education. Upon becoming NJBFAA education chairman, I decided to review all of the evaluations that were submitted by the attendees at the end of each class at the 2010 Symposium in Atlantic City. This review was used as a guide in selecting instructors and classes for the 2011 Symposium. Fortunately, we had good evaluations on most of the classes, but like all evaluations, some instructors had a better rating than others. In my review, your classes received consistently great evaluations. I would say that your classes were in the top 10% of all evaluations. Please note that I am giving my opinion on a personal/professional basis and not as an endorsement from the NJBFAA. It is my concern to provide the best instructors for the industry. With that said, I am pleased to have you back for the 2011 Symposium. Read More

In Appreciation For Sharing Your Expertise With Members Of Our Association, The Connecticut Alarm & Systems Integrators Association / CASIA Salutes
Jeffrey D. Zwirn, President, IDS Research and Development, Inc.

I have known Jeffrey since we grew up together in North Miami Beach, Florida, and we quickly became the best of friends. Jeffrey is the "Jack Nicholas" of the security industry. From an early age, in the late 1960's Jeffrey developed a passion for a number of hobbies, the most important of which was developing alarm systems. As youngsters, I would visit Jeffrey's house on almost a daily basis, and almost every day, Jeffrey would have another type of alarm system, which he totally put together from scratch. His dedication to the development of alarm systems continued through the years. When Jeffrey finally realized that he can put his unique gift on the market, he founded his own security company. His life-long experience and dedication in the security business is only surpassed by his reputation and knowledge of the security industry as a whole. I would recommend Jeffrey as an expert relating to all areas of the security industry without hesitation. Read More

This open correspondence is to serve as a warm letter of appreciation for alarm system consultant Jeffrey Zwirn, CPP, who was an invited Executive Guest Lecturer at our University in April of 2004. Jeffrey made three separate presentations on fire and security alarm systems to undergraduate students enrolled in assets protection and security, and fire safety engineering technology programs. In these presentations, he provided an overview of security and fire alarm systems; discussed alarm system liability issues; and examined terrorism and homeland security with an emphasis on alternative uses of alarm system technology. Each presentation was exceptional. Jeffrey was well organized, his slides were highly illustrative, and his enthusiasm was boundless. He tailored each presentation to the appropriate audience and engaged the students by talking about real issues and cases, and by showing slides and asking questions that encouraged them to think as professionals. For example, not only did he discuss appropriate uses of fire and burglar alarm hardware and related physical security equipment, he discussed inappropriate uses of this equipment, and showed slides of installed equipment that was improperly used and/or maintained. As part of these discussions, he provided invaluable insight on and demonstrated the need for proper alarm system policies and procedures and employee training. We felt very fortunate that he was able to visit our University and to share his professional knowledge and experiences with our students. Read More

Certificate of Appreciation awarded to Jeffrey D. Zwirn from Security Dealer Magazine, Arnold Blumenthal, Associate Publisher and Thomas S. Kapinos, Editor, for his participation on the National Security Dealer Troubleshooting Skills Examination.

I am pleased to report that Mr. Revelle was found not guilty in trial number two and is now a free man.

Mr. Zwirn's attention to detail is unmatched by any expert witness I have ever had the occasion to work with or against. Read full letter Read More
