FPV Nano Cameras Testing: Runcam Nano 2 & Racer Nano, Foxeer Predator, Caddx Kangaroo & EOS2

I tested the most popular nano cameras on the market: Nano 2 and Racer Nano from Runcam, Predator 4 Nano from Foxeer, Kangaroo and EOS2 from Caddx. Let’s compare their price, specs and performance in both day and low light to find out which is the best Nano FPV camera.

Image Testing

Here is the test footage:

I also tested the Runcam Phoenix Oscar Edition as a reference, to give you an idea how these nano cameras compared to a good micro camera.

Day Test

Although all these FPV cameras have CMOS sensor, the Caddx EOS2 and Runcam Nano 2 look a bit more like the CCD cameras with that classic warmer tone.

Not only these two cameras seem to have the same lens, the Nano 2 and EOS2 actually produce very similar image quality as well. But the Nano 2 edges out in performance with a wider FOV (field of view), brighter image, more consistent color and better WDR.

WDR Test under shadow

Many BNF micro quads are shipped with the EOS2, so I am quite familiar with this camera, I guess Caddx just sells a ton of these to manufacturers cheaply. I am not a fan of this camera because of its tendency to changes color whenever it’s struggling with lighting, and the image can suddenly become very red and orange sometimes.

The Foxeer Predator Nano still has this annoying blue hue just like the older versions, and the image color is a bit exaggerated. However, dynamic range and low light performance is pretty good. And sharpness is also great without having too much digital artifacts.

Testing shadow detail facing the sun

The default sharpness level in the Runcam Racer Nano is way too high as you can see in the testing, there are lots of digital artifacts when looking at the tree branches. But I really like the image color of this camera, probably the most natural of all. Dynamic range and low light are also excellent.

Similar to the Racer Nano, the Caddx Kangaroo also suffers from digital artifacts. Not only that, the color is very dull, and the dynamic range is just not good at all. Shadow detail under the sun is nearly non-existent, all you can see is black. However it works surprisingly well in low light.

Here are some shots from the low light testing at sunset.

Which is the Best Nano Camera?

The best budget nano camera has to be the Runcam Nano 2. I think some people might even consider this their “go-to” camera for the more consistent image quality and wide FOV.

The best performance is probably the Runcam Racer Nano 2 in my opinion. None of the newer nano cameras seem to be good enough to challenge it. It has the most natural looking image, great wide dynamic range and low light handling. The only downside however, is the over-sharpened image with stock settings, the good news is you have full control on camera settings. I’d probably turn down sharpness a fair bit to try reducing digital artifacts. And also increase contrast to bring out the detail more.

There are some desirable quality in the Foxeer Predator Nano. It supports the widest voltage range, you can power it directly from 2S or 3S Lipo battery (even up to 5S), and dynamic range is pretty good. However being the most expensive camera here at $36, doesn’t justify the kind of performance it offers. Weight is also something to think about, as the Predator Nano is over one gram heavier than the rest of the cameras tested here.

The Caddx Kangaroo seems to perform well in low light, but day light performance is mediocre unfortunately, not sure if the relatively smaller lens has anything to do with that. The EOS2 is an “okay” camera, but I’d rather spend $4 more and get the Runcam Nano 2.

    I’m a bit disappointed with the Runcam nano 2 being fixed settings, it’s a pretty good picture in daylight but it’s awful in darkness with artificial lighting, seems to be the only cam that is fixed although it is lighter than the rest from what I can see.

  2. Islandhog

    My take on this is the Phoenix is nice, and will be my next micro. As for the nano’s I’d only consider the Racer and Predator. I’m leaning towards the Predator, voltage range makes it more versatile and I’m sure the picture will be nice after adjusting the settings.

  3. Alain Assaf

    to my knowledge, runcam nano 2 can’t have it’s settings changes.
    it has only 3 wires, red black and yellow. no wire for osd.

    I am not a fan of nano runcam. i own v1 and v2 and both are annoying indoors when you suddenly face the sun.
    it takes way too much time for the camera to adjust the camera exposure.

  5. Martin

    In the initial details you say “Camera Settings Fixed” for the Runcam Nano 2, yet in the summary you say “the good news is you have full control on camera settings”. It would be nice if the summary is correct, because reducing that sharpening would make it much better I think.
