Hi
@Filbert
I've had a look online, it looks like the DVR model you have was not made for the UK/EU market (I could only find it on the
Hikvision Hong Kong site)
This means it is unlikely we will be able to confirm a UK/EU firmware that will be compatible with this DVR.
From what I can make out, the current firmware you are running is probably quite a recent version for this hardware.
The only way to figure out if there is a newer firmware would be to contact the company that sold you the DVR or Hikvision Support.
