The Alluser C4 is a dual cylindrical security portal designed to deliver high-security pedestrian access control in compact environments, ensuring robust physical protection and maximum throughput. Its overall width of 1750 mm houses two independently operated cabins, each with a 600 mm clear entrance and an 820 mm internal diameter, offering optimal efficiency without compromising on security.
Thanks to its compact footprint, modularity, and advanced access control technologies, the C4 is ideal for 24/7 applications in gyms, corporate buildings, co-working spaces, and automated facilities requiring unmanned and secure entry.
It can be equipped with the APD (Anti-Piggybacking Detection) system — an ultrasonic technology that prevents tailgating by verifying single-person occupancy inside each cabin.
