Ruijie Reyee RG-EST310 V2 5GHz 802.11ac 867Mbps Wireless Bridge (Up to 1km Point-to-Point Link)
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)

The Ruijie Reyee RG-EST310 V2 is a professional outdoor wireless bridge solution designed to replace long Ethernet cable runs with a stable and secure wireless link. It comes as a pre-paired transmitter and receiver kit, allowing quick deployment without complex configuration. Operating on the 5GHz band with 2×2 MIMO (dual-stream 802.11ac), the device provides a maximum wireless rate of up to 867Mbps, ensuring smooth transmission of HD video streams and network data across distances of up to 1km (recommended range). It is widely used in CCTV systems, construction sites, industrial areas, campuses, and elevator surveillance systems. The RG-EST310 V2 features a built-in 10dBi directional antenna with a 60° horizontal and 30° vertical beam angle, enabling stable alignment between two endpoints. It supports automatic channel selection, auto re-bridging after power loss, and cloud-based monitoring via Ruijie Cloud, making it easy to manage and maintain. Built for outdoor environments, the unit comes with an IP54 weatherproof rating and operates reliably in temperatures ranging from -30°C to +55°C. It uses 24V passive PoE power input and supports wall or pole mounting for flexible installation.
