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 M31 is an advanced industrial thermal imaging camera designed for professional applications such as construction, HVAC, and automotive inspections. Equipped with a 384 × 288 resolution thermal detector, it provides highly accurate temperature measurement and enables users to identify potential issues with precision.
Enhanced image quality is achieved through Hikmicro’s SuperIR technology, which upscales images 4X for greater detail in live and recorded radiometric images. The manual focus feature allows users to adjust clarity for objects as close as 0.1m while capturing sharp images from greater distances.
For extended use, the Hikmicro M31 includes an interchangeable battery system with two Li-ion batteries and a dual-bay charger, providing up to 12 hours of continuous operation. The camera also supports full image annotation capabilities, enabling users to add voice memos, text notes, QR codes, and image tags for improved workflow efficiency.
The device features a 3.5" LCD touchscreen display with multiple imaging modes, including thermal, fusion, PIP, and blending, allowing for customizable viewing options. The built-in WiFi and Bluetooth connectivity enable seamless integration with the Hikmicro Viewer app for real-time data transfer and analysis. Additionally, the rugged IP54-rated design ensures durability with water and dust protection, along with 2-meter drop resistance for industrial environments.
