so I think it will need firmware specific to that hardware.DS-2CD7164-E
Just use my 5.1.6 full English, thats still the best firmware with most features.
Please, give me link for your firmwarewhat is on the camera sticker and what is the build date?
If the Camera was originally 5.10 you can use my 5.16 full English firmware. Still the best one to be with
