- CCTV Lens Guide
- Hard Drive Size Guide
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.

Ruijie RG-EG105G-V3 — 5-Port Gigabit Cloud-Managed Router
The RG-EG105G-V3 is a compact, configurable router designed for small offices, retail environments, boutique hotels, CCTV setups, or home networks where reliable, flexible wired networking and cloud management are required. It features five 10/100/1000 Mbps RJ45 ports arranged as 1 fixed WAN, 1 switchable WAN/LAN, and 3 LAN ports — giving flexibility for dual-WAN setups, load balancing or failover configurations.
This router supports multi-WAN load balancing and failover, allowing you to combine or automatically switch internet sources for reliability. It handles up to 100 concurrent clients and delivers throughput up to 600 Mbps under typical load, with a “Turbo Mode” reportedly capable of reaching 1000 Mbps — enough for high-bandwidth tasks like video streaming, large file transfers, or CCTV backhaul.
For network control and security it offers built-in VPN support (IPSec, OpenVPN, L2TP, PPTP), application control and filtering, real-time traffic monitoring, captive-portal support, QoS and bandwidth control, VLAN support and advanced access-control policies. It can also serve as a management controller for other network devices such as access points and switches using the vendor’s cloud platform.
With a dual-core 880 MHz CPU, 128 MB RAM and 32 MB flash memory, the RG-EG105G-V3 provides sufficient processing power for routing, VPN and network management tasks while remaining energy efficient — consuming less than 12 W. The unit is compact and fan-less, making it suitable for desktop or wall-mount installation with minimal noise.
