mini-pro startup, preview, and recording issues

Overview

mini-pro support questions often cluster around power, unstable preview inputs, firmware upgrades, and USB recording behavior. This article consolidates the checks that solve those issues most often.

Applies to

mini-pro, mini-pro 2022

Power and startup

  • Use a PD-compliant power adapter rated for at least 20W.
  • Connect sources before powering on when possible. This reduces unstable preview detection during startup.

Preview flashing or tearing

  • If preview windows flash or tear while PST and PGM stay normal, reboot the unit first.
  • If the issue remains, test different input signals or different input ports.
  • If the issue only affects one source type, capture the exact resolution and frame rate before escalating.

Firmware upgrade checklist

  • Disable other network adapters and leave only the mini-pro LAN adapter active during upgrade.
  • Turn off DHCP on the mini-pro before starting the update.
  • After a successful update, reset and restart the device.

USB recording checks

  • Format the U-disk as exFAT or FAT32.
  • If recorded files appear silent, copy them to a local desktop before playback testing.
  • If audio is still missing, confirm the record module is on the expected firmware level.
  • Adobe Premiere Pro may fail to decode audio from some recorded files until the file is remuxed or converted again to MP4.
  • mini-pro can control up to four PTZ cameras.
  • Older firmware can also cause unstable HDMI output source selection.
