Hallo to all members. Forgive me for my english, it is not my mother language. Trying to find the correct source for upgrades (firmware, software,etc) on Hikvision, I see two websites. Tools-Hikvision Europe and http://www.hikvisioneurope.com/ There are differences between those two, like different software / firmware releases. For example SADP, at the 1st site we have V184.108.40.206 with no release date, and at the 2nd we have V220.127.116.11 with release date 22/3/2019 (18/3/2019 on release note). Also when I look for the last firmware (after V5.4.5 build 170123) for DS-2CD2020FI, at the 1st site we have DS-2CD20x0(F)-I(W) Baseline Firmware_IPC_ML_V5.4.5 170124 (2xx0) and at the 2nd we have an extra V5.4.5_Build171114(Released)breathing issue and also an V5.4.81_Build180203(Released)except mobile IPC. Which one is the correct site to trust and if they are both belong to Hikvision why they have such differences? Any ideas?
