Review: Foxeer Falkor FPV Camera

The Foxeer Falkor is a new CMOS camera featuring “Global Wide Dynamic Range” (G-WDR). It’s a feature that offers superior performance in showing bright and dark objects clearly in the same frame.

Foxeer Falkor Specifications

The Falkor offers 4 case colours: red, blue, white, black, and 2 lens options of different focal length and FOV: 2.5mm (145°) or 1.8mm (160°).

It’s designed as an all-around camera that would work well under different lighting conditions. The Foxeer Falkor is switchable in the menu between 16:9 and 4:3 aspect ratio and PAL/NTSC video formats in the settings, which makes it a great option for all FPV goggles and displays.

  • 1200TVL CMOS Image Sensor (What is CMOS?)
  • Supports OSD: Pilot name, battery voltage, timer
  • Min. Illumination: 0.01Lux
  • Supports Color and B&W
  • Input Voltage: 5V – 40V
  • Dimension: 28x26mm
  • Weight: 13.5g

What’s Included in the Box?

  • Instruction Manual
  • OSD menu joystick
  • Cables
  • Mounting bracket
  • Screws and spacers

Finally, Foxeer has added a ground pin for the OSD, so now you can connect the OSD menu joystick directly to the camera without the need for an adapter harness. This also makes it easier to connect it to your flight controller for camera control.

This is a “full size” camera (like the HS1177). On the manual there is an image of the Micro Falkor which I think might be released soon in the future.

Latency Testing

I tested the latency of the Falkor, the average delay is 33ms, which is higher than the 15ms of the Predator, and even the 25ms of the Runcam Eagle 2 Pro.

OSD Needs Work

If you plan to use the built-in OSD inside the camera for pilot name, and voltage, you are going to be slightly disappointed.

Firstly, pilot name is fixed to “FOXEER”, and you can’t change it. You can only turn it on or off.

Secondly, if you use the pin “VSEN” to monitor your battery voltage, you might notice you get a very early “Low Voltage” warning from about 3.7V percell, that’s 14.8V for 4S. I don’t see a way to change this. Maybe I miss it somehow?

If you only use Betaflight OSD, then this is not a problem at all.

Image Quality Testing

Really great image quality and sharpness! Wide dynamic range is just as good as advertised. Take a look at the sample footage during a sunny day and low light in sunset.

Optimal Settings?

The default settings work well for most situations, the only setting I recommend changing is sharpness. The default value is a bit too high and I found setting it to 1 or even 0 produces far less digital artifacts, the image looks a lot smoother.

Also you should use the correct image profile (under Special Settings), such as “Sunny”, “cloudy”, “Sunset” and “Indoor”.

Falkor vs. Eagle 2

Here is my comparison video between the Foxeer Falkor and Runcam Eagle 2 (not the pro, I don’t really like the pro).

Contrast and Color

The Falkor has a really outstanding looking image with much higher contrast and clarity. On the other hand the Eagle 2 looks a bit more “washed out”.

The color of the Falkor has a bit more green and cold tone to it, while the Eagle 2 is has a bit more magenta and warmer tone. But I personally think the Falkor produces a better color overall, it’s more vivid and natural to look at.

Sharpness

The Falkor also has a sharper image than the Eagle 2 without having too much digital artifacts. You can bump up the sharpness settings in the Eagle 2 too, but I found once you go over 5, the image becomes noticeably noisy, so I had to keep it at 5.

In the comparison, I prefer the sharpness of the Eagle 2. It’s smooth and nice to look at. I’ve set the Falkor to the lowest sharpness value and it still felt a bit over-sharpened for my taste.

WDR and Shadow Detail

When it comes to wide dynamic range (WDR), and showing shadow detail, actually both cameras performed equally well on a sunny day. I can’t quite tell which is better in this respect.

Sun Glare

I get a bit more sun glares in the Falkor (reflection in the lens). When the camera is facing the sun at certain angle, it produces multiple big red circles and they take up a good part of the frame which can be distracting.

Low Light

I am surprised that both cameras did a decent job in low light. When I was testing them, it was very dark and getting difficult to see the surrounding clearly with the naked eyes.

The Eagle 2 still has an advantage in low flight, because it’s showing the colours and detail very well. The Falkor is beginning to struggle, the colour is getting very dull, and the shadow detail is also getting too dark to see clearly.

High Light Handling

Not sure why, but with the Falkor, I am getting this black dot in the middle of the light source. For example, when I point the camera at street lamps or car head lights.

Don’t Set Auto Day/Night

There is a bug with Auto Day/Night mode. At certain brightness level it would repeatedly switch between color and B/W, causing the screen to flicker. This should be an easy software fix by Foxeer, but it’s only likely in future batches.

Set it to either color or B/W for now.

Conclusion

The prettiest camera isn’t always the best camera, but the Falkor is just too pretty to be true :D I really love the beautiful image quality, probably one of the best in that regard!

The Foxeer Falkor has awesome image color, detail, WDR, and FOV. However it suffers from bad lens flare like the Predator we tested previously. Maybe it’s a problem caused by the similar lens they use on these cameras?

Another downside is the slightly higher latency. But it shouldn’t be an issue at all for casual pilots, considering it’s on a similar level as the Runcam Eagle. But if you are really serious about racing, then you might want to consider faster cameras like the Runcam Racer or the Foxeer Predator v3 :)

    I think the Foxeer Falkor Micro is now released. Please make a article about its features and functionality and a head to head comparision to the Foxeer Predator v3

      Yes I am getting one hopefully soon. But according to Foxeer, the Micro version uses exactly the same sensor and firmware as the full size one, so i think the image quality should be on par with the full size one.

    Oscar,

    I strongly suspect the 16:9 mode is simply the 4:3 with top and bottom cropped off. But there is ZERO information on this. The only information I find on this is on the Banggodd web site and the image they used is obviously NOT taken by this or any other video camera.

    Could you measure the FOV in both 4:3 and 16:9 modes. Just shoot a picture of a brick wall and count the bricks

    Or simply un-screw the lens and show us a photo of the sensor.
