This NVR will accept any capacity hard drive (HDD) currently available. Any maximum capacity stated on the manufacturer’s documents is simply based upon the maximum HDD size that was available at the time of release/publication Face Picture Library Up to 16 face picture libraries, with up to 50,000 face pictures in total (each picture ≤ 512 KB, total capacity ≤ 1 GB) You can also use the Hikvision online calculator to work out what works best for you specifically: https://tools.hikvision.com/ca...

A power supply is included with this. AI by Camera Facial recognition, perimeter protection, video structuralization, throwing objects from building, motion detection 2.0, ANPR, people counting, VCA

Specification

As a rule of thumb, we recommend 2 Terabytes for a 4 x 4/5MP HD camera setup, as this should give you approx 2 weeks using H.265 @ 20fps and that is on continuous, not motion-detected recording.

After ultra HD resolution mode is enabled, the NVR supports up to 8-ch 32 MP/24 MP IP video inputs.

The amount of hard drive space you require is dictated by how many cameras, as well as their resolution, frame rate settings, and whether you have H.265 encoding enabled or not to save space (We advise turning it on to double the capacity shown below with ease). Narrows down the angle and zooms in to look past the immediate area a little to gain more detail - down a driveway for example from higher up Unless selecting a vari-focal camera (with an adjustable lens) It is important to select the correct camera lens option for where the camera is to be positioned. A smaller lens will give you a wider angle but will be "zoomed out more", while a bigger lens will narrow the angle down and "zoom in more".
