The ease of use and intuitive interface makes it simple for users new to Access Sentry to navigate, especially with the help from our support team. I also like that we can customize all aspects of the screen as well as easily manage custom fields and rules in order to streamline process. Having access sentry has made it easier for our company's front desk workers to know who's visiting so they are able to better focus their time on important business tasks rather than being constantly answering questions about guests' names and appointments. It's easy to use, I can see who entered my office in real time which helps me keep track of clients when they are visiting our offices for appointments! We have not found any downsides yet but if you don't like something it could be changed by contacting their customer support team at anytime day/night 7 days per week via phone call (888) 599-9555 ext 3010 / 3020.
