Hikvision HiLook DVR-216U-M2 16 Channel 8MP 4K AcuSense Hybrid DVR
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". See below to give you some idea on angles of Megapixel HD Cameras:
| Lens in mm | Approx Viewing Angle (degrees) | Ideal Distance (metres) | Typical usage/notes |
|---|---|---|---|
| 2.8 | 106 | <6 | For seeing as much of the immediate area as possible such as above a doorway/low down/garage soffits (edges can appear slightly warped/distorted) - clearly "zoomed out" |
| 3.6/4 | 83-90 | <12 | A great general purpose option giving great coverage still in the corner of a room or higher up on second floor soffits with less distortion - more of a natural "zoom" |
| 6 | 56 | 6-20 | 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 |
| 12 | 24 | 20+ | Zooms in significantly more to look at a gate, entrance or adjascent building |
| 16 | 19 | 24+ | As above but more so |
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).
Finally, you can often make your storage space last a lot longer by enabling motion-detected recording rather than continuous, especially if there are long periods of no activity (to perhaps double or more these figures again).

Resolution (Megapixels) |
Days of storage provided by 1TB per camera (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (50% motion- 15 frames per second) |
|---|---|---|---|
| 1 | 44 | 11 | 36 |
| 2 | 22 | 5 | 18 |
| 3 | 17 | 4 | 14 |
| 4 | 11 | 3 | 9 |
| 5 | 9 | 2 | 8 |
| 6 | 8 | 2 | 6 |
| 8 (4K) | 5 | 1 | 4 |
| 12 | 4 | 0.5 | 3 |
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.
(You may only require the full 25 frames per second on certain cameras if things are fast-moving - ie above a till)

HiLook DVR-216U-K2 16 Channel Turbo HD DVR
The HiLook DVR-216U-K2 is a 16-channel hybrid Turbo HD DVR designed for larger analogue and mixed-technology CCTV systems. It supports HDTVI, AHD, HDCVI, CVBS and IP cameras, making it a flexible choice for new installations or upgrades where existing coaxial cameras are being retained.
The recorder supports up to 8MP HDTVI input and can encode footage at up to 8MP at 8fps. It also supports up to 8 additional IP cameras as standard, giving a total of up to 24 channels, while enhanced IP mode can increase IP capacity further.
H.265 Pro+ compression helps reduce storage requirements and bandwidth usage, while dual SATA interfaces support two hard drives for extended recording capacity. HDMI output supports resolutions up to 4K, and the recorder also offers remote viewing through HiLookVision-compatible network services.
Please note: this DVR does not record AcuSense-filtered events only; it records all motion detection. AcuSense is used for intelligent alerts and event searching during playback, either directly through the DVR or via iVMS-4200.
