Dahua NVR4216-4KS3-L 16-Channel 4K Network Video Recorder

With 16 recording channels, the NVR4216-4KS3-L can handle footage from up to sixteen network cameras on a single recorder. That covers a typical office, shop, warehouse or larger private property, where entrances, car parks, corridors and storage areas each need their own camera. Running everything through one recorder keeps the system easier to manage than several smaller units spread across a site.

The recorder supports a resolution of 3840 x 2160, the 4K standard. When paired with 4K-capable cameras, this lets you keep the detail those cameras capture instead of downgrading it at the recording stage. Higher-resolution footage makes it easier to pick out faces, number plates and small objects when reviewing an incident, and to zoom into recorded video without the image breaking down as quickly.

As a network video recorder, this unit works with IP cameras connected over your local network rather than with analogue coaxial cameras. Footage from every channel is collected in one place, which simplifies playback, searching and exporting clips. For details on supported camera protocols, network ports and remote access options, check Dahua's official documentation, as these are not listed in the specifications here.

The specifications provided do not list the number of drive bays, the maximum supported hard drive size or whether drives are included. Storage requirements depend on the number of cameras, their resolution and how many days of footage you want to keep, since 4K recording takes noticeably more space than lower resolutions. Confirm the drive configuration with Dahua's datasheet before planning your retention period.

This recorder suits small and medium businesses, retail premises, offices and larger homes that need more than eight cameras and want to keep the option of recording in 4K. It also fits installers building a Dahua-based CCTV system who need a 16-channel unit as the core of the setup. Smaller installations with only a few cameras may find a 4- or 8-channel recorder sufficient.
