Dear sir
i have the same problem, there is a red dot next to “firmware”
Hi, Sir/Madam,
you can upgrade it via TF card. the operation steps as follows:
1. Prepare a SD card, copy the latest version files to SD card. Firmware download URL: http://download.eye4.cn/fm/UP_Firmware/CH-sys-48.50.64.86.bin
2. Power off camera, then insert SD card to your camera's card slot;
3. then power on camera, it can auto upgrade after restart. |
