The DS-KD-ACF1/PLASTIC is the single-module flush mounting bracket for Hikvision's DS-KD8003 modular door station range.
Flush mounting recesses the door station into the wall for a near-flat finish, and the bracket doubles as the back box — set into the wall at first fix, with the module fitted afterwards. It is the tidier option for new build and for entrances where a surface-mounted panel would be exposed to knocks.
Single-module size takes a DS-KD8003 camera module on its own: a video door station with one call button and nothing else. It is the smallest, simplest build in the range and suits a house or a single-occupancy commercial door. For builds that add a keypad, card reader or nametag module, step up to the DS-KD-ACF2 or DS-KD-ACF3. For surface mounting instead, use the DS-KD-ACW range.
