According to our supplier, the B version is a discontinued model. The main difference between the Hikvision DS-KV8213-WME1(B) and DS-KV8213-WME1© models lies in the specific functions and possibly in the hardware revision. The B version has a 2 MP CMOS color camera with strong residual light amplification, which enables clear images even in low light conditions. The C version will also be equipped with a 2 MP camera, but improvements in image processing or additional functions could be integrated here. You can find the data sheets under the following links:
