Seeking an old firmware level (V2.800) for this camera, IPC-PFW8840N-A180.

I've exhausted searches on google and duckduckgo. I can find the "V3.000" level firmware, but I need older than this unfortunately. The newer level of firmware, unfortunately, brings the IVS analytics down to a crawl in terms of speed.

Hoping someone here has something. Firmware would include "HX8XXX-Four-Nobel" in the name.

You have links to two 2 servers with old Dahua firmware.
You can try to find more proper versions there

Yeah. And these were sites I had already encountered. However, I did not locate these specific firmwares. Unfortunately, these firmwares are flawed for this camera also, which actually calls for the Four-Nobel firmware: I haven't located earlier versions of this.

The proper firmware version 3 will splice correctly. It's just so unfortunate the IVS analytics are so much slower to respond.

This appears to be firmware for a dual lens. The PFW8840 is a four lens.

The internal hwid file provides for the following:
"IPC-HDW8343X-B-3D:01:02:00:9F:34:00:01:10:07:03:04:4B0_4B0:08:00:00:0D:00:01:00:00:800",
"IPC-HDW7343X-B-E2-S2:01:02:00:9F:34:00:01:10:07:03:04:4B0_4B0:08:00:00:0D:00:01:00:00:800",
"IPC-HDW8343XP-3D-S2:01:02:00:9F:34:00:01:10:07:03:04:4B0_4B0:08:00:00:0D:00:01:00:00:800",
"IPC-HDW7343X-E2-S2:01:02:00:9F:34:00:01:10:07:03:04:4B0_4B0:08:00:00:0D:00:01:00:00:800",
"IPC-HDW7343X-PC-M-E2:01:02:00:9F:34:00:01:10:07:03:04:4B0_4B0:08:00:00:0D:00:01:00:00:800"

I don't think that firmware will work in the slightest.
