Note*: It is necessary to download the V3.2.2 upgrade file for the C182 camera and the V1.7.2 upgrade file for the ZR16DK POE NVR respectively, and perform the upgrade operation for both to ensure the fix takes effect.

8. Increased the 823C and 826 IPC adaptability;

9. Fixed the problem that the 3536c formatted hard disk consumes too much memory and causes aging or formatting with probability of crashing;

10. Modified the problem that the upgrade interface does not show IP address and version when OTA upgrades c182gk7605v100+k05;

11. Fixed 16-way live audio no sound problem.

The following are the step-by-step instructions for upgrading the DVR/NVR specific operations:

To perform this process, you will want to use a USB 2.0 drive ideally 16 GB or less in size, formatted in FAT32.

After you have downloaded the update file from the link above, please note that this file should be placed in the root directory of the USB (not in any folders) and the file name must remain the same for the DVR/NVR to recognize it.
Some customers have reported issues when downloading this file using the "Microsoft Edge" browser. We recommend using a different browser for this process.

In case it helps, here is a link to a Youtube video demonstrating the process:

If you're unfamiliar with how to format a USB in FAT32, this video provides the steps:

If you're not seeing an "updating..." message on the screen for at least three minutes, the DVR/NVR isn't detecting the update file. There are a few reasons this could be: 

1) If the DVR/NVR has alternative places to look for the update, it won't run. The ethernet cable needs to be disconnected, as well as any other USB devices including the mouse. The power should be disconnected for at least 10 seconds before connecting the USB drive and reconnecting the power.

2) If the USB is 3.0, the DVR/NVR will not be able to read it. USB 3.0 was developed after the DVR/NVR motherboards. Likewise, the DVR/NVR is not in FAT32 format, it won't be read. The easy way to tell if a USB drive is 3.0 is the color of the board chip inside the USB connection. 2.0 always uses a black board, while 3.0 generally has a colored board, often red or blue. 

3) The file name must remain exactly as listed in the article for the DVR/NVR to recognize it as an update. If the file was downloaded twice, a PC will add (1) to the end of the name, which will create an issue. If the file was downloaded using the Microsoft Edge browser, this will cause the file to be converted to a text file, which can't be read by the DVR/NVR. 

4) The DVR/NVR cannot navigate through folders in the USB to find the update. The file must be placed in the USB root directory. 

Please let me know if you have any questions!
