The world of FPV drones has been rapidly evolving, with more pilots transitioning from analog to digital systems. However, the options have often been limited to high-end solutions like DJI and Walksnail, which may not fit everyone’s needs or budget. Enter RunCam WiFiLink—a new, open-source digital HD FPV system built on the OpenIPC platform. In this article, I’ll explore what makes the RunCam WiFiLink a potential game-changer for both new and experienced pilots, breaking down its features.

What is RunCam WiFiLink?

The RunCam WiFiLink is a digital HD FPV system designed to provide a high-quality video feed directly to your mobile device or computer.

This setup includes a RunCam camera capable of 1080p resolution at 90fps (or other options like 1080p/60fps or 720p/120fps), powered by a Sony IMX415 sensor with a 160-degree field of view.

The system is controlled by a two-board VTX (video transmitter module)—one board runs the OpenIPC firmware, while the other is a WiFi module equipped with two antennas and a cooling fan.

At first glance, the design of the Runcam system is somewhat unusual. The transmitter consists of two boards connected with only two standoffs. This design raises concerns about durability during crashes. If the boards aren’t securely mounted, they’re likely to shift or break during a hard landing. Even though this is an alpha product, it’s clear that this hardware isn’t quite ready for the average consumers.

Understanding OpenIPC

Before diving deeper into the WiFiLink system, it’s important to understand the foundation it’s built on—OpenIPC. OpenIPC is an open-source firmware created for IP cameras. It replaces the often restrictive, closed firmware that comes pre-installed on most cameras, offering flexibility and compatibility across various hardware.

Key features of OpenIPC include:

  • Native H265 Encoding Support
  • High-Definition Video Transmission
  • Low Latency
  • Cost-Effective and Flexible

RunCam WiFiLink Features

RunCam’s adoption of OpenIPC for their WiFiLink system marks a significant advancement. As a major player in the FPV camera market, RunCam brings credibility to this open-source platform. Here’s why WiFiLink stands out:

  1. Open-Source Foundation: The WiFiLink system is built on OpenIPC, fostering a community-driven approach to development and customization. This allows users to tailor their FPV experience to their specific needs.
  2. Affordable HD Quality: At just $69.99 for the base kit, WiFiLink offers HD video quality at a price comparable to traditional analog systems, making it accessible to a broader audience.
  3. Low Latency: Essential for control and navigation, WiFiLink aims to provide HD video with minimal delay, although exact latency figures are not yet disclosed.
  4. Flexible Configuration: Supporting multiple resolutions and a wide voltage range (9-30V), WiFiLink can be adapted to a variety of setups and use cases.
  5. Compact Design: Weighing only 30 grams, the WiFiLink system is lightweight and compact, making it suitable for a range of drone sizes, from micros to larger builds.

One of the key features of the Runcam WiFiLink is that it uses a customized WiFi module for video transmission. While it may sound limiting, this module has been customized to optimize range and performance. The transmitter also includes a cooling fan, which is necessary to prevent overheating during use.

However, inserting and removing the SD card, which is necessary for both DVR and configuration, is a bit of a hassle due to the placement of the boards. This design oversight adds to the feeling that this is still a work-in-progress rather than a polished, ready-to-use product.

Getting Started with RunCam WiFiLink

Setting up the RunCam WiFiLink is straightforward but requires a bit of patience. Unlike more plug-and-play solutions from DJI or Walksnail, you need to configure various software tools, including apps and drivers.

RunCam provides a kit that includes the camera, the necessary components, two antennas, and the 8812AU Wireless Network Adapter with an OTG cable, simplifying the setup process.

To receive video, you can use an Android smartphone or tablet with a Wi-Fi dongle and the FPVue app. While this isn’t as streamlined as some other systems, the flexibility it offers is worth the extra effort for those willing to tinker.

The Setup Process

  1. Install the Camera: Mount the RunCam camera on your drone, ensuring it is securely in place and connected to the video transmitter module.
  2. Connect the Components: Attach the video transmitter module and the WiFi module to the drone, ensuring proper power supply via the 3S-6S compatible connectors.
  3. Software Configuration: Install the necessary apps on your mobile device, and configure them to recognize the WiFiLink system.
  4. Test the Setup: Power on the system and check the video feed on your device. Make any necessary adjustments to optimize video quality and latency.

What About Latency?

RunCam has not disclosed specific latency figures for their HD video transmission solutions, and this is a critical factor for many FPV pilots. Latency can affect control and reaction times, especially in fast-paced environments or races. Until real-world testing data becomes available, we’ll have to reserve final judgment on this aspect of the WiFiLink’s performance.

Conclusion

The RunCam WiFiLink is a promising new entry in the world of digital HD FPV, especially for those looking to move away from analog without the steep price tag of other digital systems. By leveraging the open-source OpenIPC platform, RunCam has created an affordable solution that make HD FPV accessible for many pilots. While it may require a lot more setup and patience than some alternatives, the potential for customization and community-driven improvements makes it an exciting option to consider.
