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.

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.

Ruijie RG-ES126FGS-P — 24-Port PoE+ Unmanaged Switch with Gigabit Uplinks
The Ruijie RG-ES126FGS-P is a high-capacity unmanaged PoE+ switch designed for reliable wired networking in CCTV systems, offices, retail spaces, and other setups that require multiple powered devices. It provides both data and power to IP cameras, wireless access points, VoIP phones, and other PoE-enabled devices.
It features 24 × 10/100 Mbps PoE+ ports and 2 Gigabit uplink ports (one RJ45 and one combo SFP/RJ45), offering a total PoE power budget of 370 W with up to 30 W per port. This ensures multiple high-demand devices can operate simultaneously without additional power sources.
The switch is fully plug-and-play, requiring no configuration. It supports operational modes including default, port-isolation for enhanced security, and extended-reach mode for long cable runs up to 200 meters. A durable metal chassis and fan-assisted cooling ensure reliable, long-term operation. With a switching capacity of 8.8 Gbps and a forwarding rate of 6.55 Mpps, it delivers smooth data flow even under heavy loads.
