Hello everyone,
I am new on here, and have decided to share my concerns looking for getting some help.
I have purchased 2 x DS-2CD2135F-IWS from an eBay seller, where I was told they are Multi-language models, which basically means, they are Chinese with an "firmware mod" to be able to show several languages in Web GUI.
One of the cameras came with firmware version 5.4.0 build 160401 ( serial number containing AA and CH ) and the other one is 5.4.24 build 170303 ( serial with AA and WR ). Seller told me repeatedly not to update the firmware, otherwise, it would revert to chinese language only. Also told me that Hikvision recommend to not update firmware unless if any problem comes up, which I think is false, because manufacturers usually recommend to use the latest versions in order to fix security issues or improve some features.
As both cameras are Wireless, both are also vulnerable to the recent WPA2 security hole named KRACK. Hikvision states that some models, where the 2xx5 is included, are vulnerable to this problem if using 5.4.0 firmware. They have fixed this issue on later versions like 5.4.5, however, I can not use the European or US firmware file to update my cameras, as I am afraid they may get bricked.
So I have searched on Hikvision Chinese web site, and found out a file that matches my model, which is "IPC_G0_CN_STD_5.4.41_170710".
Here's the direct link :

My question is : As the file was downloaded from CN website, can I use it without any problem to update my cameras ? To get Multi-language GUI again, do I need to modify the file "before" or "after" to proceed the update ?
All help would be much appreciated
Many thanks
