Applies to

mini-mx

Power and startup

• Use the supplied power adapter whenever possible.
• If you must replace it, use a 12V 3A adapter with sufficient power headroom.
• If the unit still fails to start, verify the power cord and adapter before assuming device damage.

U-disk recording issues

• Format the U-disk as exFAT or FAT32.
• Avoid multiple partitions on the same U-disk.
• If the screen turns black when inserting a recording disk, the disk may be locked or read-only.
• For firmware updates, use a standard OTG cable and confirm the firmware file is in .img format.

USB webcam issues

• Confirm the computer meets the expected baseline for CPU, memory, operating system, and USB 3.0 connectivity.
• Reconnect the USB cable and re-enter the streaming software.
• Lower output resolution if the capture path is unstable.
• If needed, test through a Type-C to USB 3.0 hub or fall back temporarily to USB 2.0, understanding that image quality is lower.

Additional notes

• mini-mx supports VISCA PTZ control, not Pelco.
• HDMI input 1 supports HDCP 2.x; the other HDMI inputs support HDCP 1.x.
• If the firmware is very old, the upgrade may need to pass through intermediate versions before you can install the latest release.
