IP camera Techage TA-XM-608GP-AI-30 (3MP)


  • Full AliExpress name: Techage H.265 3MP Two Way Audio POE IP Camera IP66 Waterproof Outdoor Video CCTV Security Surveillance Camera for POE NVR System
  • Bought on AliExpress, at the time for $35 (shipped from EU warehouse)
  • Model: Techage TA-XM-608GP-AI-30
  • Lens: 3.6 mm
  • Power: either 12 V DC, or 48V PoE
  • Default login: admin/null
  • Administration: requires Internet Explorer + ActiveX plugin
  • Resolution: on the sticker 3MP, but within the settings the highest resolution is actually 4MP at 2560x1440 (so something like 3.6 megapixels, also called 1440p or QHD)
  • Framerate: 1-25 fps (can be adjusted)

Worth mentioning

  • This camera can do both H264 and H265 (HEVC) stream. When the codec is set to H.265X, the stream is actually x264 (and H265 is actual x265).
  • The stream carries wrong aspect ratio metadata (should be 16:9, but it's actually 64:27). See ffprobe output bellow. Can be fixed without re-encoding, but it's annoying.
  • There is some (2-way) speaker that was always buzzing. I cut it off. NOTE: Other Techage camera was the same way, but only when powered on by 12 V. When powered over ethernet (POE) it was quited. So POE is preffered way of powering.
  • Default IP is with DHCP disabled.

Fixing the wrong aspect ratio without re-encoding

Before I come up with better solution, this works well. It simply adjusts the display aspect ratio (DAR), so players know to play it back as 16:9.

ffmpeg -i in.mp4 -aspect 16:9 -c copy out.mp4

Sample footage

Will add at some point. Overall very nice image for $35.
