Frontier is a great system. We've been using it for a couple years now and we've had no issues with it. When I left the company this year, I had to switch to a new company and Frontier was not an option. We are using the system to track and report on access to the building. The system is easy to use and the reporting is great! They've been great to work with. If you're looking for a great system, I wouldn't look anywhere else. Access control and reporting. We are able to track who is in the building and when they are there. The reporting is great!
