The DS-KD-KK is the nametag call-button module for Hikvision's DS-KD8003 modular door station range, fitting the standard modular frame alongside the camera, keypad, card reader and display modules.
Each module carries a labelled push-button, so a visitor presses the button against the name they want rather than needing to know a room number. For houses, small blocks and offices with a handful of occupants this is usually the most straightforward option — no screen to read and nothing to memorise. Larger buildings tend to be better served by the DS-KD-KP keypad and DS-KD-DIS display combination instead.
Requires a DS-KD8003 camera module as the host unit, plus a DS-KD-ACF flush or DS-KD-ACW surface mounting bracket to suit the number of modules fitted.
