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)

The HikMicro HM-G630-LENS is an interchangeable 3.3X telephoto lens designed for use with HikMicro G Series Thermal Imaging Cameras, including the G40 and G60 models. This lens expands the original camera’s focal length, enabling users to capture detailed thermal images from greater distances.
With a focal length of 82mm, the HM-G630-LENS provides a narrower field of view (FOV) to enhance long-range thermal detection. The lens offers a FOV of 7.6°(H) × 6.1°(V) for the G60 model and 5.7°(H) × 4.3°(V) for the G40 model, allowing for more focused thermal imaging in precise areas of interest.
The lens maintains a high level of accuracy with a maximum deviation of ±3°C (±5.4°F) or ±3%, ensuring reliable and consistent thermal readings. The minimum focusing distance is 3.2 meters (3.5 yards), making it suitable for both distant and moderately close thermal imaging applications.
This lens is ideal for professionals in various fields, including building inspections, electrical maintenance, industrial diagnostics, and security applications, who require an extended focal length for precise, long-range thermal imaging.
Key Features:
- Telephoto 3.3X lens for enhanced long-range thermal detection
- Focal Length: 82mm
- Field of View (FOV): G60 – 7.6°(H) × 6.1°(V); G40 – 5.7°(H) × 4.3°(V)
- Accuracy: Max ±3°C/5.4°F or ±3%
- Minimum Focusing Distance: 3.2m (3.5 yds)
- Designed for use with HikMicro G40 and G60 models
