looking for Firmware 5.2.0 for hikvision DS-2CD2112-I

[Goldbug]

hello,
I am new here, Not sure if i post at the right place, if not I'm sorry.

I got 4 Hikvision IP cameras all 4 with WR in the serial number.
2 DS-2CD2132-I cameras which i was able to upgrade to Firmware v5.4.0 without problems
1 DS2CD2042WD-I which is running firmware v5.5.0

and one DS-2CD2112-I (1.3Mp) which is running firmware v5.1.2.

i would like to upgrade the firmware of the last camera DS-2CD2112-I to v5.4.0 but cant seem to fine anywhere on the web firmware V5.2.0.
I think i need this before upgrading to 5.3.0? right?
can anyone help to source firmware v5.2.0.

many thanks

Wow! That's a big collection.

It looks like a home user hosting a nginx server.
