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 G41 Handheld Thermography Camera is a high-performance tool designed for precise temperature measurement in a variety of industrial environments. Equipped with a 480 × 360 resolution thermal detector, the G41 enables users to quickly identify high-temperature targets, providing essential data for decision-making and ensuring safety. With a wide temperature measurement range from -20°C to 650°C, this camera is ideal for applications in building inspections, electrical utilities, and the oil and gas industry.
The camera features a 4.3-inch LCD touch screen with a resolution of 800 × 480, offering excellent clarity for thermal imaging. It supports multiple palettes, which helps to visualize temperature variations more effectively. The G41 also includes a high-quality 8 MP optical module and bi-spectrum image fusion for picture-in-picture previews. With long-distance laser light and LED light supplements, it enhances thermographic accuracy and serves as a flashlight when needed. Additionally, the camera supports continuous digital zoom from 1.0x to 8.0x for more detailed imaging.
Included with the Hikmicro G41 are several useful accessories, including a 64GB micro SD card, rechargeable batteries, a charging base, international power plugs, USB cable, CVBS patch card, and more.
