Not everybody has the chance to fly throughout daylight, or maybe you simply wish to discover the night time sky together with your FPV drone. On this article, I’ll share important ideas and methods to make sure you fly safely at night time and enable you select the perfect analog FPV digicam for low mild.
You’ll be able to study extra about FPV cameras on this purchaser’s information: https://oscarliang.com/fpv-camera/
The Greatest Low Mild FPV Cameras
Whereas there are numerous FPV digicam choices in the marketplace, not all are suited to low-light situations. Happily, every main FPV digicam model presents a digicam particularly designed for these situations. I’ve carried out complete testing on all of them to offer you an in depth roundup!

Day and Evening Footage Comparability
I hope you get pleasure from this sort of content material and take into account supporting me on Patreon. Creating this comparability took me a complete day and price over $150 shopping for these cameras.
In low mild situations, the Runcam Evening Eagle 3 and Caddx Ratel Professional emerge because the clear winners! They each carry out exceptionally nicely, even in near-total darkness. The presence of only a few streetlights considerably improves visibility. The Evening Eagle is noticeably much less noisy/grainy than the Ratel Professional, displaying its unmatched low mild efficiency.
Throughout the day, each the Caddx Ratel Professional and the Foxeer Cat 3 ship excellent photos. The Ratel Professional’s picture high quality is nice – it’s extra contrasty, sharper, and the colours are extra vivid, nevertheless it simply feels oversharpened and you may see the digital noise. The Cat 3 presents a softer and smoother picture. In my preliminary assessment, I questioned the Ratel Professional’s small discipline of view (FOV) in comparison with typical FPV cameras. Now I start to surprise if Caddx was simply making an attempt to align with their rivals’ low-light cameras, as I spotted that each one three cameras function a equally slender FOV.
Total, the Caddx Ratel Professional stands out as the perfect all-rounder, excelling in each day and night time. The Runcam Evening Eagle 3’s low mild efficiency takes the crown, nevertheless it solely works in black and white, due to this fact it’s much less suited to daytime flying.
How Properly FPV Cameras Carry out At Evening?
Low mild succesful cameras excel at maximizing accessible mild. Their efficiency in low mild setting is measured by a parameter often known as “LUX.” The decrease the LUX worth, the superior the digicam’s night time efficiency. At the moment, it’s doable to seek out FPV cameras boasting as little as 0.00001 LUX in black and white mode, very best for night time flying.
Right here’s an instance demonstrating the capabilities of those cameras at night time. Beneath is how darkish the playground seems to the bare eye or via an ordinary cellphone digicam:

Contrastingly, right here’s the identical scene considered via our low-light succesful FPV cameras, considerably enhanced even with out further mild sources:

Nevertheless, with out the advantage of a transparent sky and a full moon, or the illumination from close by avenue lights, your digicam should face challenges in offering a crisp picture. That’s the place a DIY IR torch would turn out to be useful.
Constructing IR Torch
In extraordinarily darkish environments, the picture high quality of your FPV digicam can considerably degrade, leading to noisy and blurry footage that’s troublesome to navigate with. Nevertheless, there’s a sensible answer to this drawback.
A technique to enhance visibility with out sacrificing the stealth side of night time flying is through the use of IR (Infrared) LEDs . In contrast to seen mild, IR mild is invisible to the human eye however might be detected solely by digital cameras.
The simplest answer I’ve discovered includes utilizing 48 IR LED boards, which price round £6 (US$8). The one modification required was soldering a feminine steadiness plug connector to the LED board, enabling direct connection to a 3S battery, as they take 12V enter. In case you are utilizing 4S or 6S LiPo, you may want an exterior voltage regulator to step all the way down to 12V.
Get this IR LED board from:
I merely mounted the LED board on a GoPro mount, inserting it on prime of the quad. This setup is especially handy as a result of it permits for angle changes.
For these with out a GoPro mount, take into account the inventive various shared by fellow pilot, Konrad Stepanajtys. He mounted the LED panel on a cardboard field, which then sits on prime of the quad.
To stop glare, make sure the LED is positioned away from the digicam lens.
In contrast to a peculiar torch, the IR LED doesn’t produce a obvious white spot however as an alternative emits a tender, widespread glow, enhancing visibility with out being obtrusive.
Suggestions for Utilizing a DIY IR Torch:
- Your FPV digicam should NOT have an IR filter with a purpose to successfully see the IR mild.
- Hold the IR LED at a distance out of your digicam lens to keep away from reflective glare, which may scale back visibility.
- Confirm the voltage necessities of your IR LED panel. My 12v panel connects on to the quad’s 3S LiPo battery by way of the steadiness port. If utilizing a 4S or 6S LiPo, a voltage regulator or BEC from the flight controller will probably be essential to provide energy appropriately.
Flying Suggestions for Low Mild Circumstances
Black and White Mode: In your FPV digicam, modify the Day/Evening setting to auto or set it to black and white. This mode offers higher visibility at night time, decreasing digital noise in comparison with shade mode.
Sluggish Down: The decreased visibility inherent to nighttime flying means it is best to fly slower to permit sufficient time for reacting to obstacles.
Keep Line of Sight: In low mild situations, it’s difficult sufficient to navigate; you don’t wish to compound that problem with sign points by flying behind obstacles. Even with a transparent digicam feed, maintaining your drone inside visible line of sight ensures dependable video transmission and is a vital security apply.
Get a Spotter: Flying with a spotter who can provide you with a warning to approaching folks or animals you may not see in your goggles can enhance security.
Select Location: Flying in areas with some mild sources, akin to close to avenue lights, can considerably enhance visibility at night time.
Add a Self-powered Buzzer and Tracker: To stop dropping your drone, attaching a buzzer with an built-in battery is advisable: https://oscarliang.com/drone-buzzers-with-battery/. A tracker may assist find your downed drone extra simply.
GoPro Settings for Low Mild: In case you’re capturing your flight with a GoPro, take into account my really useful settings for low-light situations, accessible right here: https://oscarliang.com/gopro-settings-fpv/#For-LowlightNight-Capturing
Digicam Comparability in 2018
Again in 2018, I carried out a comparability of a number of low mild FPV cameras, most of which have since been discontinued. Nevertheless, they may nonetheless be accessible second-hand, so I’ve determined to depart the video right here. The cameras had been examined at night time in two areas with completely different ranges of brightness.
On this specific check, the Runcam Evening Eagle emerged because the clear winner, although it’s value noting it solely works in black and white, making it much less interesting for daytime use.
The Runcam Micro Eagle barely outperformed the Runcam Owl 2 Professional, regardless of the latter being designed for low mild situations. Nevertheless, the Owl did exhibit much less digital noise in testing. Notably, the Eagle provided superior picture high quality throughout the day in comparison with the Owl, positioning it as a extra versatile “All-Round” digicam. Thus, the Micro Eagle ranks as my second alternative.
The Foxeer Falkor stood out for its distinctive daytime picture high quality – arguably among the many finest. But, for low mild or night time flying, I discovered it unsuitable, primarily attributable to a bug within the “Auto Day/Evening” mode that brought about the display screen to flicker at sure brightness ranges attributable to fixed switching between shade and black & white. A useful tip for decreasing digital noise in low mild is to regulate the DNR setting from 0 to 1; I noticed no additional enhancements by rising it past that.
Conclusion
Evening flying with FPV drones presents an unmatched expertise. With the appropriate digicam, cautious planning, and adherence to security and rules, pilots can safely discover this difficult but rewarding side of drone flying. As you enterprise into the night time, keep in mind that thorough preparation and choosing the appropriate gear are essential.
