Hikvision's DS-KD8003-IME1(B)/NS (HIK-KD8003-IME2N) is a modular door station for cameras only, it is specifically designed for the 2-wire range which is great for retrofitting existing sites. This stainless-steel version is built to withstand harsher weather conditions which allows it to suit a wider range of applications.
This range is perfect for site upgrades and maintenance as it is compatible with the whole range of IP and 2-wire intercoms, including all door modules. Being modular adds the flexibility to install on sites such as small residential 1-to-1, to large apartment complex deployments.
