2) Disable scan and preset point scan functions.
3) Fix an issue where the PTZ camera asks whether the IPC supports human tracking but does not receive a response when it is wirelessly connected while being connected to a wired connection.
4) In app.sh, add rm -rf /mnt/sapicu* to prevent backups from being stored in this directory due to unknown reasons, which can cause a lack of storage space in the flash drive.

How to upgrade the system?

Step 1 You needn't open the upgrade file, please scroll down directly to the bottom of this article and download the attached upgrade file rootfs-mc6810.

(Please save the upgrade file rootfs-mc6810 in the root directory, not save it under any other folders.)

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

Some customers have reported issues when downloading this file using the "Microsoft Edge" browser.

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 NVR. We recommend using a different browser for this process.

Step 2 The file name must remain exactly as listed in the article for the DVR to recognize it as an update.

It should be rootfs-mc6810, if the file name is changed to rootfs-mc6810(1), the upgrade will be failed.

Step 3 Before starting to upgrade, please unplug the power supply and mouse, then plug the U-disk and re-plug the power supply. 

Step 4 It can upgrade automatically as long as it has electricity, the upgrade process need to last several minutes, please be patient. 

What if it doesn't work?

Dont be worry.

If the upgrade is successful, please go to the NVR’s Main Menu > Information > System to check if the firmware version and Launch date have changed.

If the upgrade is failed, we suggest you change another U-disk or USB port to try.

Please let us know if you have any questions.
