Frequently Asked Questions (FAQ) ​

Answers to the questions beginners and experienced OpenIPC users ask most often. Every answer links to a detailed guide.

General ​

What is OpenIPC? ​

OpenIPC is open source firmware that turns ordinary IP cameras into digital FPV systems. It is free, has no regional locks and runs on a wide range of hardware — from off-the-shelf Runcam WiFiLink to fully DIY builds.

→ Comparison with DJI, Walksnail and HDZero — on a dedicated page.

How much does an OpenIPC FPV system cost? ​

A minimal kit starts at ~$60–100: a camera from ~$40 plus an Android smartphone with a Wi-Fi adapter as the ground station. A kit with a Runcam WiFiLink v2 and a DIY ground station on a Radxa Zero 3W — roughly $150–250.

Why is OpenIPC better than DJI or Walksnail? ​

Price, openness and flexibility: no power or region locks, any compatible hardware, a ground station built from anything — a phone, a Radxa, a laptop. It trades away simplicity: it is a kit you assemble and configure yourself. Detailed comparison — here.

Hardware ​

What hardware should I buy to get started? ​

The simplest proven kit:

A full breakdown of the options — in the Quick Start.

Is OpenIPC suitable for TinyWhoop? ​

Yes. EMAX Wyvern Link and OpenIPC Thinker v1 with Wi-Fi (100 mW) weigh next to nothing and give up to ~500 m of range — enough for indoor and park flying.

Which Wi-Fi adapters are supported? ​

The most common:

AdapterNotes
RTL8812AUSimple, 3.3V, connects to a Radxa directly
RTL8812EU2More powerful, needs 5V and a USB hub
RTL8731BUCompact, close-range only

Drivers are already included in ground station images — network cards overview.

Can I watch FPV video on my phone? ​

Yes. The PixelPilot Android app receives video from OpenIPC cameras through a Wi-Fi adapter (WFB-NG) or directly over the drone's Wi-Fi network (APFPV), shows OSD telemetry and records DVR.

Firmware & configuration ​

Which firmware should I pick — APFPV or WFB-NG? ​

  • APFPV — for beginners: the drone creates a Wi-Fi network you simply join with your phone. Minimal setup.
  • WFB-NG — for experienced users: lower latency (down to ~35 ms), longer range and a more robust link, but a more involved setup.

What is the video latency of OpenIPC? ​

It depends on firmware and settings: APFPV — 40–70 ms, WFB-NG — from ~35 ms. Resolution, bitrate, channel bandwidth and ground station performance all affect latency. Parameter tuning — in the WFB-NG configuration.

Adaptive-Link automatically adjusts bitrate and transmitter power based on signal quality — up close the picture is as sharp as possible, at the edge of range the link does not drop. For long-range flying it is definitely worth enabling.

How do I update the camera firmware? ​

Over SSH with the sysupgrade command (from the internet or local files) or with the OpenIPC Configurator. Before updating, have a recovery plan: a rescue SD card or a UART adapter.

Troubleshooting ​

No video on the ground station. What should I check? ​

The most common causes, in order:

  1. gs.key mismatch between camera and ground station
  2. Different channel or bandwidth (e.g. 161 / 20 MHz)
  3. Unsupported Wi-Fi adapter or insufficient adapter power
  4. Lens cap removed? 🙂

After checking, reboot both sides.

The camera does not respond over SSH. How do I recover access? ​

The default camera address is 192.168.1.10 (login root, password 12345). If ping fails, connect through a UART adapter: it gives console access even when the network is down.

How do I flash or recover a Runcam VRX? ​

Flashing — with the emmc_flasher image from an SD card. Recovery after a failed flash — with RKDevTool in loader mode. A step-by-step guide with photos — here.
