With electronic access control, you have the ability to truly manage your facility by monitoring and establishing controlled access entry points to main entrances, secure rooms within buildings, elevators, stairwells, and doors. If needed we can also add a complete cctv surveillance system to complete the perimeter defense.
In addition, keyless entry has proven to be a highly effective means for easily handling employee safety and turnover as well as protecting a company's infrastructure from internal and external losses. Access control, as part of a business security alarm system can be an incredible money saving tool by eliminating re-keying with each employee departure.
Certified Systems will work with you to design a perimeter security system that utilizes electronic access control to meet your specific requirements. Soon after your custom system is drafted, our trained technicians will install, service, and support your new system.
Certified Systems works with the finest manufacturers to guarantee both product efficacy and usability. With a variety of options available to choose from, you’re sure to find exactly what you need.
Our access control and security systems can include any or all of these features:
