HIKVISION 4CH. DVR

The HIKVISION 4‑Channel DVR is a compact digital video recorder designed to record and manage footage from up to four CCTV cameras. These DVRs typically support multiple video formats (like HDTVI, AHD, CVI, CVBS), use H.264/H.265 video compression to save storage space, and provide HDMI & VGA output for live monitoring on a connected TV or monitor. Most units include features such as motion detection, remote viewing via mobile apps (Hik‑Connect), synchronous playback on all channels, and support for large HDD storage (up to several TB).

Depending on the model, advanced variants may also support deep learning‑based motion detection (human/vehicle), higher recording resolutions, and audio over coax inputs. These DVRs are typically plug‑and‑play, easy to install with BNC cables and a compatible monitor, and are suitable for residential and small commercial security setups.
