Harrisburg Commercial Security Systems

No matter if you started a business to be your own boss or if you are a trusted officer or manger of a larger company, you know that loss prevention is a mandatory part of running a business. Whether it’s internal theft, break-ins, stolen property, or that insurance claim incident you wish you had a video clip of, it all does the same thing; eats into profits.


We here at Knight Security Systems understand that when it comes to commercial security, not all systems are equal. 


To that point, Knight Security Systems has now partnered with Honeywell Security and we are proud to offer business owners and managers like you the opportunity to affordably, comprehensively safeguard your business with tools and systems that address your every security need and from a name that you know and trust.


Also, after decades of hard work, integrity, and an unwavering commitment to our clients we are proud to announce that Knight Security Systems has been selected as a Honeywell Authorized Dealer of Commercial Security Systems.


That means we offer you:

Since 1979 we have provided all-inclusive commercial security services to some of the most prominent businesses in Harrisburg and Central Pennsylvania. We would be honored to do the same for your business as well.
