Ruijie Reyee Mini-GBIC-GT 1000BASE-T Gigabit RJ45 SFP Transceiver - 100m Copper Module
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)

Ruijie Reyee Mini-GBIC-GT 1000BASE-T Gigabit RJ45 SFP Transceiver – 100m Copper Module
The Ruijie Mini-GBIC-GT is a hot-pluggable SFP (Small Form-Factor Pluggable) transceiver module that enables Gigabit Ethernet connectivity over standard copper cabling.
It converts an SFP slot into a 10/100/1000BASE-T RJ45 interface, making it ideal for extending network connectivity where fibre is not required or available. Designed for enterprise, campus and data centre environments, the module supports auto-negotiation and delivers stable Gigabit performance over Cat5e, Cat6 or Cat6a cables up to 100 metres.
Its plug-and-play design allows for quick installation without network downtime, making it a practical solution for expanding switch or router port availability. The Mini-GBIC-GT is widely used for connecting network switches, routers, servers, and other Ethernet devices where flexibility between fibre and copper infrastructure is required.
It is fully compliant with IEEE 802.3ab standards and SFP MSA specifications, ensuring broad compatibility with Ruijie and other networking equipment.
Key Features
- 1000BASE-T Gigabit Ethernet SFP module
