For the highest possible security level, Chameo offers the Security cylinder product package. These cylinders ensure that access is granted to only 1 person at a time. This level of control is possible through the application of volumetric measurement and/or weight measurement. The cylinders are available in two diameters and different embodiments and can be equipped with a bullet-resistant glazing. Placing an intercom system and/or biometric verification in the cylinder is also an option.
