Who is the DVR-204U-M1 for?

A 4-channel U-series HD-TVI recorder: the same 5MP, H.265+, 5-in-1 recording as the Q-series, plus AcuSense — the recorder itself classifies movement as person or vehicle and ignores the rest, so a small coax system gets app alerts that mean something. It is the DVR for a house or shop with 2–4 coax cameras where the owner actually wants to be notified when someone is on the drive, not every time a cat crosses the garden. Any channel takes TVI, AHD, CVI or analogue; IP cameras can be added. For audio over coax with mic cameras, the DVR-204G-M1/T; for 8 channels with AcuSense and audio, the DVR-208U-M1/T.

What to add

• A surveillance-grade hard drive — 1–2TB for four cameras; we fit and format to order.
• Coax cameras plus RG59 cable and a 12V PSU — the DVR does not power cameras.
• A network cable to your router for the free HiLookVision or Hik-Connect app.

Frequently asked questions

Does AcuSense need special cameras?

No — the analysis runs in the DVR on any connected camera, including old analogue ones.

Will it work with my existing cameras?

Yes — CVBS, TVI, AHD and CVI auto-detect per channel.

How is it different from the DVR-204Q-M1?

Same recording spec; the U adds AcuSense person/vehicle filtering.
