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 HABROK 4K HQ35L delivers cutting-edge multi-spectrum performance in a compact, high-precision format. Featuring a highly sensitive 640x512 thermal detector with <20mK NETD and an advanced 4K CMOS optical channel, the HQ35L ensures exceptional clarity and detection in all lighting and weather conditions—from open daylight to total darkness.
Equipped with a 60mm F2.2 lens and dual replaceable IR illuminators (850nm & 940nm), this unit adapts to a wide range of use cases—hunting, birding, search and rescue, and marine observation. The 1000m integrated laser rangefinder ensures pinpoint distance calculation, while the ergonomic chassis and intuitive controls offer seamless, on-the-fly operation even in field conditions.
The integrated image stabilization algorithm minimizes blur and vibration, delivering steady visuals across the 5.5x to 22x zoom range—ideal for scanning, tracking, and recording with precision. Its dual-spectrum system allows thermal and optical fusion, detecting hidden heat sources while preserving visual detail through the 0.49” OLED display at 1920x1080 resolution.
With an IP67 waterproof rating, 8+ hours of runtime from replaceable 18650 batteries, onboard 64GB storage, and built-in GPS, compass, and hotspot functionality, the HQ35L is engineered for endurance, clarity, and mission-critical performance. Whether spotting through dense foliage or capturing low-light wildlife footage, the HQ35L delivers reliability where traditional optics fall short. Experience the future of binocular technology with the HABROK 4K HQ35L.
