The available modes include Repeater, AP (Access Point), WISP Client, WDS (Wireless Distribution System), AP+WDS, and Router. The setup wizard guides you through the configuration process.
3.4 Dyagram Koneksyon
The CF-E312A V2 is designed for Point-to-Point and Point-to-Multi-Point wireless connections. For stable 5-10km transmission, it is recommended to use two CPE units configured as a wireless bridge.
3.4.1 Point-to-Point Connection (Multiple Cameras Way 1)
Connect the camera(s) to a network switch, then connect the switch to one COMFAST CPE (configured in Terminal mode). The data is then transmitted wirelessly to a second COMFAST CPE (configured in AP mode), which connects to a DVR or monitoring computer.

Figure 5: Point-to-Point Connection Diagram (Way 1)
3.4.2 Point-to-Point Connection (Multiple Cameras Way 2)
If cameras are far apart, configure each camera with its own CPE. The control center connects to a CPE in AP mode via a switch, which then connects to a DVR. Each camera's CPE (in Terminal mode) wirelessly connects to the AP mode CPE.

Figure 6: Point-to-Multi-Point Connection Diagram
Important Note for Multi-Point Connections: If the angle between the camera and monitor center is less than 60 degrees, a single point-to-multi-point connection can be considered. This can reduce the number of CPEs needed in transmitting mode, saving project costs. Ensure the connection meets the required angle and broadband requirements. For wireless monitoring transmission, pay attention to the device's transmission angle, which is 60 degrees.

8. Konsèy itilizatè yo
- Pairing for Long Distance: For optimal and stable 5-10km wireless transmission, it is highly recommended to purchase and configure two CF-E312A V2 units to act as a wireless bridge. A single unit cannot achieve this long-range transmission on its own.
- Liy Vizyon: Ensure a clear line of sight between the two CPE devices for the best signal strength and stability. Any obstacles can significantly reduce performance.
- Angle for Multi-Point: When setting up a Point-to-Multi-Point connection, be mindful of the 60-degree transmission angle of the device. If the angle between the camera and the monitoring center is less than 60 degrees, a single point-to-multi-point setup might be sufficient.
