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)
You can also use the Hikvision online calculator to work out what works best for you specifically: https://tools.hikvision.com/ca...
(All of our hard drives come fitted and are CCTV-specific from one of the major brands)
- High definition: 4 MP HD camera with max. 2688 × 1520 resolution and 25 fps frame rate.
- Low illumination: High quality imaging with 1/3" progressive scan CMOS. 0.022 lux low illumination with clearer imaging at night.
- Supplement light: Embedded with 9 bright LED lights, the device has smart supplement light technology, which supports supplement light control according to time and brightness.
- Allowlist and blocklist control: Supports importing and comparing the allowlist and blocklist, barrier gate linkage, and working offline.
- Multiple trigger modes: Supports triggering via video, loop, radar, etc. It provides high capture rate and recognition via video. It can capture vehicles without license plates, and the capture rate is higher than 99.9%.
- Anti-vehicle following mode: Supports anti-vehicle following mode via video and radar/loop. The boom pole can keep rising in vehicle queue scenario to solve the congestion.
- Ingress protection: The surface of the host adopts anti-UV and electrostatic spraying, and the level of dustproof and waterproof meets the requirement of IP54 for outdoor devices.
- Easy construction: The all-in-one structure brings simple wiring and convenient debugging, and can shorten 1/3 of the construction period.
- Support Wiegand: with protocol included CardID 26bit, SHA-1 26bit, Hik 34bit, NEWG 72bit
