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)

HIKMICRO Habrok 4K – Entry Level thermal binocular
The HIKMICRO Habrok 4K 2.0 HE25L is a highly advanced multi-spectrum digital and thermal binocular with integrated laser rangefinder, purpose-built for demanding daytime and mixed-light applications. Designed for hunting, wildlife observation, search and rescue, and field exploration, it combines thermal detection, true 4K digital imaging and precision ranging into a single, ergonomic platform capable of performing in all weather conditions.
At its core is an ultra-sensitive 256 × 192 thermal sensor with <18 mK NETD, paired with a fast 25 mm F1.0 lens delivering reliable thermal detection out to 1200 metres. This allows heat signatures to be clearly identified through foliage, mist and low-contrast environments. HIKMICRO’s HSIS Shutterless Image System ensures uninterrupted viewing without image freezing, maintaining smooth, stable observation during dynamic use.
For daylight performance, the Habrok 4K 2.0 features a 3840 × 2160 UHD CMOS digital sensor combined with a 60 mm F2.2 lens, providing exceptionally sharp imagery with 5.5x to 22x zoom. The dual-channel optics architecture allows instant switching between thermal and digital modes via a dedicated control, giving rapid situational awareness from dawn to dusk.
An integrated 1000 m laser rangefinder with ±1 m accuracy enhances precision for scouting and navigation, while replaceable 850 nm and 940 nm IR illuminators provide adaptable night-time illumination for both range and discretion. Advanced onboard features including electronic image stabilisation, picture-in-picture, video and audio recording, GPS, compass and hotspot connectivity further elevate its capability in the field.
Despite its performance, the Habrok 4K 2.0 remains highly practical, weighing just 895 g with a compact, balanced design optimised for extended use. A replaceable rechargeable battery system delivers over 6.5 hours of runtime, while IP67 protection ensures reliability in harsh environments. Supplied with batteries, charger, IR illuminator and accessories, and backed by a 3-year HIKMICRO warranty, it is a powerful all-in-one observation tool for serious users who demand versatility, clarity and precision.
Please note: Due to distribution rights and agreements we can only sell HIK-MICRO products to residents of the UK.
