The security intercom system 2N Helios IP Verso features an intuitive touchscreen, card reader and discreet camera with infra-red light and night vision. The metal construction is resistant against strong temperature fluctuations and sudden weather changes. The system is supplemented by the 2N Indoor Touch intercom which features a clearly structured touchscreen and an integrated video camera. The moment the bell is rung, the video image of the entrance appears on the colour monitor.
