The Hik-Zenith series is used for access control and security management of buildings. It consists of a master, an outdoor and an indoor station. Its clear design featuring high-strength alloys and glass lends all components a uniform appearance. Directional sound pickups in hi-fi stereo ensure clarity of voice transmissions even in noisy environments. In combination with the dynamic facial and voice print recognition, smooth and trouble-free identification is guaranteed. The pressure-sensitive buttons are water-repellent and thus well-suited for outdoor use.
