Product Spotlight: Openpath

Welcome to sophisticated access control. Whether you’re upgrading an existing system, or starting from scratch, Openpath solutions from Security Instrument can completely modernize the accessibility of any building in a snap.

Welcome To Modern Access Control Solutions.

Sophisticated and Seamless Access Solutions for Any Enterprise.

Our story started when we noticed how much was missing from the keyless entry experience. What was out there didn’t work well, didn’t look good, and was overpriced. The moment we went all-in on creating a new standard for the industry, we knew we were on to something big.

For the office that doesn’t want to compromise ease for security, Openpath is innovative, intelligent access control that automates your security infrastructure, so you can focus on managing your business.

We’ve worked extremely hard to build a company that can offer a new, seamless style of security that takes advantage of new technologies, and makes people feel safe at work. Access Control is the flagship product in our mission to improve the quality and safety of the modern workspace through automation.
