Frederick County Public Schools (FCPS) searched for a suitable solution that would enable their employees to evaluate visitors prior to entering school buildings, using cameras and door intercoms.

FCPS selected 2N® intercoms as the ideal solution, combining cost-effectiveness with security requirements. Their schools are now equipped with our 2N® Helios IP Force intercoms with an electronic-card reader, ensuring keyless employee access. They also meet the client’s requirements for integration with their existing school telephone systems. Employees can now both see and communicate with incoming visitors, prior to their admittance.
