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 SP40H-L37 is a high-performance thermal imaging camera designed for industrial inspections and extreme high-temperature measurements. With a 480 × 360 infrared resolution, a wide field of view (37.3° × 27.8°), and a temperature range of -40°C to 2200°C (-40°F to 3992°F), this camera provides precise and reliable thermal detection.
Equipped with three focus modes (manual, automatic, and laser-assisted autofocus), as well as a laser rangefinder, it ensures quick and accurate distance measurement. The NETD < 30 mK sensitivity captures the smallest temperature variations, making it ideal for metallurgy, power plants, and industrial applications.
The 5-inch LCD touchscreen with 90° tilting and 180° rotating lens enhance usability, allowing for comfortable operation in difficult inspection environments. GPS, Wi-Fi, and HDMI connectivity enable seamless data transfer and reporting, while the replaceable battery provides up to 4 hours of continuous operation.
Key Features:
- High-resolution infrared sensor: 480 × 360 pixels (172,800 pixels)
- Exceptional thermal sensitivity: NETD < 30 mK (@ 25°C, F# = 1.0)
- Wide temperature measurement range: -40°C to 2200°C (-40°F to 3992°F)
- High accuracy: ±1°C (±1.8°F) from 0 to 100°C, ±1% from 100 to 150°C
- Wide field of view: 37.3° × 27.8° for broader thermal coverage
- Three focus modes: Laser-assisted autofocus, manual focus, continuous autofocus
