Firmware hikvision model DS-96256NI-I24

[rosendo]

Hello everyone. I'm requesting your assistance because I have a Hikvision NVR, model DS-96256NI-I24. I'm trying to update it; I currently have firmware version v4.1.64 build 190423 and I'm looking for a more recent version, v4.1.66, so I can then upgrade to the latest version, v4.1.51.127.

The problem is when I search for and download the zip files even from Hikvision, it appears as .iav file and not .dav file. Does anyone know of a link or the file itself where I can download them?

Thanks for your help

Hi @rosendo

Have you tried installing the .iav file?

I've had a look at several sources for Hikvision firmware, all of which are using the .iav file for this NVR model.

I don't know why, but for some reason, it looks like Hikvision is using .iav files for the firmware for these NVR models.

I appreciate the response. I haven't tried it yet because I have approximately 230 cameras connected and no NVR backup, and I don't want to risk it until I'm sure.
