Hikvision's HIK-KD-KK-S is the stainless steel version of the six button module. This robust model is designed to withstand harsher weather conditions suiting a wider range of outdoor applications.
This range is perfect for site upgrades as this model can be easily retrofitted from standard model and is compatible with the whole range of IP and 2-wire intercoms, including all door modules. The modular design adds the much-needed flexibility as it suits smaller sites such as residential installations which are one to one, all the way through to large apartment complex deployments with numerous room and door stations.
