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)

Hikvision 3K Dual-Lens 180° Smart Hybrid Light HDTVI turret Camera
Experience full-scene coverage and crystal-clear imaging with the Hikvision 3K Dual-Lens 180° Smart Hybrid Light Camera. Designed for wide-area monitoring, this innovative camera uses a dual-lens system and a built-in stitching algorithm to deliver a seamless 180-degree panoramic view — ideal for open spaces such as car parks, courtyards, or building perimeters.
Featuring a 3K resolution (3328 × 1504) image sensor and an F1.0 large-aperture lens, this camera ensures vivid, full-colour imaging around the clock. The Smart Hybrid Light technology provides flexible lighting options, intelligently switching between infrared and warm white light to achieve the best balance between discretion and visibility in low-light environments.
Even in challenging lighting conditions, the camera’s 130 dB true WDR (Wide Dynamic Range) and 3D DNR (Digital Noise Reduction) technologies maintain sharp, balanced images with reduced glare and noise. With up to 40 metres of IR and white light distance, you can rely on clear detail even at night.
For added security and convenience, a built-in microphone delivers high-quality audio recording over coaxial cable, allowing you to both see and hear what’s happening on-site. The rugged IP67-rated housing ensures long-term durability against dust and water, making it a reliable choice for both indoor and outdoor installations.
