DS-2CD2021G0-LIU 4mm

The Hikvision DS-2CD2021G0-LIU 4mm is the audio-equipped 2MP IP bullet with a tighter lens for distance. Same Hikvision build quality and audio capture as the 2.8mm version, in a focal length that delivers usable detail at 8 to 12 metres rather than peripheral coverage at close range.

The 2MP bullet with audio, narrower lens

The 2.8mm version of this camera covers a wide scene up close. The Hikvision DS-2CD2021G0-LIU with the 4mm lens trades that peripheral coverage for usable detail at 8 to 12 metres, with the same built-in microphone and audio capture. The right call when you want audio and visual context together, but the camera position is further from the subject than a wide-angle lens can handle well.

What this camera is actually good at

  • 2MP resolution with 4mm lens. 84° horizontal view. More usable identification detail per person at distance.
  • Built-in microphone. Audio captured alongside video.
  • IR illumination up to 30 metres. Total-darkness coverage at residential and small-business distances.
  • IP67 weather-sealed. Built for outdoor mounting.
  • H.265+ compression. Storage-efficient.
  • Standard motion detection. Trade-off that keeps the price reasonable.

Where this camera belongs on your property

  • Side passages watching the gap between the house and boundary wall, with audio context
  • Garden and patio mounts 8 to 12 metres from the activity area
  • Cottage and outbuilding entries from across an internal courtyard
  • Small business loading bays where audio of arrivals adds context
  • Carports watching parking bays from a corner-of-house mount
