Hello, newbie here.
Ive never upgraded the firmware of my 3 cameras that are about 4 years old. One camera has started playing up and keeps disconnecting itself so I would like to update the firmware.
Model DS-2CD2355FWD-I
The current version is V5.4.5 build 170124 and I can see the latest is V5.6.6 20210625. There are lots of previous updates.
My question is do I need to download each previous update, one at a time, or can I just go straight to the latest one? I suspect I probable need to install some of the early ones.
Many thanks, Steve
 
Hi @SteveEvans

There shouldn't be an issue updating to the latest, but to be safe (as you are so many versions behind) we would recommend first updating the oldest version listed on the UK portal currently - v5.5.80 - before then updating the latest v5.6.6 firmware.
