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 and frame rate settings. 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.
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 a minimum of 2 Terabytes per 4 x 2-4MP HD cameras, as this should give you 2 weeks to a month with a few adjustments on motion detected recording. You may only require the full 25 frames per second on certain cameras if things are fast moving.

HIKMICRO HM-LH25 Lynx PRO 25mm 384x288 12um Smart Thermal Monocular
HIK Micro has introduced the Lynx Pro 25mm to build on the success of the Lynx Pro 19mm with a higher magnification big brother making it perfect for detecting and identifying over longer distances.
This Lynx Pro 25mm utilises HIK Micro’s 384x288 12um sensor with a 25mm lens system to achieve a detailed image. The 2.4x optical magnification delivers longer detection distance which makes the Lynx Pro 25mm a powerful and versatile unit suited to a variety of situations. The sub 35 NETD performance of the sensor ensures detection of small temperature changes and excellent performance in harsh conditions.
The Lynx pro 25mm offers the same software as the other HIK monoculars and includes 4 colour palettes, white-hot, black hot, red hot and fusion. The Lynx Pro can also record video or images with the onboard memory or connect to the T-Vision app to seamlessly share or record your shooting experience.
