Annke Firmware to Hikvision Firmware: HOW TO

все будет работать, появится дополнительный функционал, метки в приложении человек и автомобиль, можете смело обновиться.
Hi everyone, I have a DT81DX that I want to upgrade to V4.75 to enable the event markers on the playback timeline in the remote app (yeah, I know). I contacted ANNKE and I was told the latest they had for this unit was V4.71.111_231226. From reading a few replies to this thread, it is possible to use the original Hik firmware on this DVR, but I want confirm a few things before attempting this.
  1. For people who have upgraded this or other ANNKE recorders (NVR/DVR), has functionality been reduced? Did it result in a brick?
  2. Will the download from hikvisioneurope work, or will I need to find a NEU variant? If it is the latter, it looks like Mazisecurity has it available for download, but it might rebrand the unit.
  3. Is the platform K20A9S? A user claimed to have successfully used ids-7208huhi-m1/s firmware on this device.
  4. Am I correct in assuming that I'll have to unlink the device from ANNKE Vision before the upgrade and link it with Hik-Connect afterwards? Has anyone had issues with registration after doing this?
everything will work, additional functionality will appear, tags in the application are a person and a car, you can safely update.
for annke app you can use hik-connect
 
I would like to flash back the Annke CZ504 firmware, I'm currently on Hikvision firmware. The upgrade results in an error: "Upgrade error. Please contact our technical support for troubleshooting.", is there a fix/workaround?
 
Becoming sick of this stopid annke garbage with the 191DW or also known as FCD600, i decided to flash a hikvision firmware to it of the hikvision DS-2CD2367G2P-LSU/SL.

I simply flashed the downloaded zip file on the web admin page, and it worked, i now have a hikvision camera, lol! even settings were still there.
Hopefully the WDR and HLC are now working, without the camera failing after seconds, minutes or hours at random, with hlc or wdr enabled.
I will report back in hours/days if it is working better.

Thanks for the shared tip that we can flash hikvision firmware!

Funny joke: I now have a lower resolution camera then before......... Which is ofcourse nonsense. Annke was lying about the 8mp resolution. image quality is exactly the same as well.

I have the FCD600. Also flashed Hik firmware, no issues from 16 months ago. 6MP 2 x 3MP. Not 8MP.
Sensor is poor but reasonable for the near on 180 view.
 
The IDW191 is definitely advertised as a 4k camera, 2x 4mp. it is however a lie.
In any case, it seems the issue with wdr and hlc is solved using hikvision firmware. the image quality was and is sufficient, but not great no.
