i dont know if anyone should answer this... quick search of chinese model hikvision and there is ton of information.
No You cannot flash properly... many people tried and they end up with 50% working GUI... english/chinese
the worse thing is that you dont have warranty... for 200$ (4x) you saved by purchasing overseas how much will you spend replacing it...
Alex- thank you for beating me to the punch. Aliexpress customers must go back to the Aliexpress store for support and warranty. The Firmware is different and cannot be upgraded to USA GUI. Also, all DS-2CD3xxx cameras are only for the local China market. For DVR/NVR, if it doesn't have an I in the model (ex. NI-ST suffix), it is for the China market.

Had to explain this to a few customers the other day, I just refer them to the hikvision website of listed non-authorized dealers.
Btw, what type of price differences has anyone seen between Chinese and USA versions of Hikvision cameras? I am curious how significant it is.
Amazon does not police their stores in that manner or any manner as far as I am concerned. It would be easier for manufacturers if they did.

The Chinese version has it's date(weekday) stamp as well as few other properties in Chinese, and starting from this year, the chinese version with newer firmware will not be compatible with the upcoming US/europe verision of iVMS software. This is done by hikvision to protect regional distributors.
There is a way to flash it, so the GUI works and you can disable to weekdays, it almost look the same as the US one until you try to reset or update them. but warranty is the number one issue. not to mention some of the components are different depends on the actual production date of the IPC. plus, the Chinese version does not have to meet certain standards too.
I would strongly recommend you to buy Hikvision product or hikvision OEMs from your local or regional distributor. also, pay close attention to what version that you are getting from them. I wouldn't be surprised if some of them is still trying to dump the Chinese version.
The latest firmware doesn't allow you to select English if you have a chinese version camera. As recommended above, if using these cameras for jobs or selling to others, stick with the US Version and pay the few extra dollars.
Now if you are installing for yourself or family and are willing to support the cameras, changing the setting in the latest firmware is pretty easy.
You will still need to flash with the Chinese firmware, but can add english back to the menu. There are methods to actually change the firmware region, but I wont get into that, and HikVision may decide to detect and prevent that change in the future.
First, if you are doing this from Windows, pickup a few free tools (putty, 7-zip & HxD)
Login to the camera via the browser
Go to Advanced Configuration -> first category (System) -> last tab -> check Telnet
Use Putty (or your favorite telnet program) to login. Use the browser password (admin/12345)
FTP the Davinci file to your FTP server - /bin/ftpput -u cctvdump -p cctvdump <FTP Server IP Address> davinci.tar.gz /dav/davinci.tar.gz
Grab the davinci.tar.gz file from your FTP server
Use 7-Zip on Windows (or whatever tool you want to use to unzip, un-tar the file) and first unzip the file, then tar the file to extract the davinci file, almost 10MB.
Open the file with the hex editor (I use HxD)
Search for 8a 30 dd e5 38 a0 9d e5 53 90 c4 e5 14 90 9d e5
Change string from 38 a0 9d e5 to 01 a0 a0 e3
Tar the file then gzip the tar file (right click on file, use 7-Zip archive, default settings for both)
Copy the file to your FTP server
Put the file back in the camera - /bin/ftpget -u cctvdump -p cctvdump <FTP Server IP Address> /dav/davinci.tar.gz davinci.tar.gz
reboot (just type reboot in telnet)
Login to the camera and all is in English
replace <FTP Server IP Address> with the xxx.xxx.xxx.xxx address w/o brackets <>.
Also change cctvdump/cctvdump to use whatever username/password you have for the FTP server.
For Andrew and Jack just for fun

Buy Hikvision cameras and support the Communist government of China. The Hikvision rep sat in my office and told me the company is 51% owned by the Chinese government. We will not use them and I do not believe our customers want them either.
Speaking of goods and tariffs, don't you have to deal with U.S. Customs when purchasing equipment direct from China? How does that work?
The reason I ask is that we are interested in obtaining Evetar lenses (Xiamen Leading Optics Co.) but they apparently don't sell in the U.S., despite having an office in Claremont, CA. Yes, I know both Axis and Arecont sell Evetar lenses but for the one we are particularly interested in (M125VM3312IRR7, which equals Arecont's MPL33-12A) we would pay around $120 each versus Evetar's quoted price of $34.80 each FOB Xiamen, China. We're just not set up to import.
