So here is a trick taught to me, also by
@JSnP
When saving firmware files (Especially with the same filenames), it is important to get the actual file date (Last-Modified Date) instead of using the date created when you downloaded the file. This is much easier to keep up all these firmwares this way since the filename remains the same on EZVIZ's sites. I would just save the files in their own directories labeled with their Date & Build #.
To do this, use
Wget, It is a free command line DOS program that connects to the URL Link/Site to retrieve the last or original file date. The downloaded file will be dated with the last-modified (original release) date, which is what you want, see below:
Once in the GnuWin32/bin Directory type:
wget --server (firmware URL/filename)
For those not familiar with basic DOS commands:
Click on Windows Start button, type CMD
(Normally you will end up in your Users directory)
(If you installed Wget on a different drive other than C: see below)
To change a drive simply type the drive letter and colon, ex.
D: then hit ENTER
To change directories use the
cd command, ex.
cd Program Files (x86)\GnuWin32\bin
To get a Directory listing;
dir
If you ever need help with a command; Type
/? at the end of the command, ex.
dir /?
A few more help commands:
If you want only the directories or files that start with W for example, use this command;
dir w*.*
The
* is filename or extension; ex
dir *.html
To get to your Root Directory;
cd\
These are just the Basics, there are many other commands that do similar things, also many other short cuts.

I will leave you with this tip, if you ever needed to know where/get to your TEMP directory; Click on Windows Start button, type
RUN, then type
%temp% Hit OK
