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)

Introducing the new Lynx 2.0 25mm thermal monocular. Sharing the same design philosophy,
robust build quality and high performance thermal sensors as the class leading Falcon and Condor
monoculars, the Lynx 2.0 redefines expectations from entry level thermal products.
High performance thermal – At the core of the Lynx 2.0 25mm is HIKMICRO’s latest generation,
384px Sub 20 mK NETD sensor that pairs with the advanced, F1.0 lens to detect very small changes
in temperature and deliver an incredibly detailed image, even in the most challenging conditions. The
15mm Focal length offers 2.4x base mag with up to 8x digital magnification giving you 2.4-19.2x
magnification range.
Compact and powerful - Built on a robust magnesium-alloy chassis, the Lynx 2.0 has a distinctly
premium feel from the first time you pick it up. The updated chassis design also features a removable
18650 battery delivering up to 6.5 hours of run time. The ergonomic buttons fall easily to hand and
allow you to intuitively take control of the main features, even in complete darkness. The large OLED
screen gives a great view of your surroundings while the soft eyecup prevents unwanted light spill.
Digital connectivity – The Lynx 2.0 is supplied with the latest HIKMICRO software which gives you
fast access to commonly used options like brightness and contrast and allows you to add a PIP
screen to your monocular. The Lynx 2.0 offers a choice of four thermal colour profiles, the ability to
record pictures or video and WiFi to allow you to connect, stream and control from the HIKMICRO
sight app.
The lower the NETD value, the better the imaging
Thermal imaging works by sensing tiny differences in temperature, and the more sensitive the sensor
is to minute contrasts, the better and more clear the image in the viewfinder. Lynx 2.0’s sub 20mK
NETD sensors capture the sharpest, most informative images, even in challenging conditions; this
means that you can not just find the heat of people, animals and birds, but capture the detail of the
surroundings to aid identification.
Convenience is king
The Lynx 2.0 has been redesigned to maximise convenience in every area. The size and weight, at
under 175mm in length and under 300g with battery, combine with the rugged build and comfortable
rounded shape to produce a powerful device that can easily be carried and used at all times. The new
power system uses industry-standard rechargeable 18650 batteries for a continuous run-time of up to
6.5 hours, which can be renewed by a quick switch of the battery to a (supplied) spare. Lynx 2.0 also
features a 3 second Fast Boot time, to easily keep pace with the action in the field.
Integrated phone or tablet hotspot
HIKMICRO’s Sight App links Lynx 2.0 to your phone or tablet, creating a second display and adding
functionality: You can control the device via the app, view and share recorded images and video,
share the thermal view with others in your group, and control and update the software settings.
The Lynx 2.0 is the perfect, versatile companion device for hunting, ecological survey, wildlife
observation, search & rescue and security applications. The affordable price, high performance and
robust, proven build make it a natural choice and it seems well set to take over the best-seller crown
from its much-loved predecessor.
