Not everybody has the chance to fly throughout daylight, or maybe you simply wish to discover the night time sky along with your FPV drone. On this article, I’ll share important suggestions and methods to make sure you fly safely at night time and enable you select the perfect analog FPV digital camera for low gentle.

The Finest Low Mild FPV Cameras
Whereas there are numerous FPV digital camera choices available on the market, not all are fitted to low-light circumstances. Happily, every main FPV digital camera model affords a digital camera particularly designed for these situations. I’ve carried out complete testing on all of them to give you an in depth roundup!

Day and Night time Footage Comparability
I hope you get pleasure from one of these content material and take into account supporting me on Patreon. Creating this comparability took me a complete day and value over $150 shopping for these cameras.
In low gentle circumstances, the Runcam Night time Eagle 3 and Caddx Ratel Professional emerge because the clear winners! They each carry out exceptionally properly, even in near-total darkness. The presence of just some streetlights considerably improves visibility. The Night time Eagle is noticeably much less noisy/grainy than the Ratel Professional, displaying its unmatched low gentle efficiency.
Through the day, each the Caddx Ratel Professional and the Foxeer Cat 3 ship excellent pictures. The Ratel Professional’s picture high quality is nice – it’s extra contrasty, sharper, and the colours are extra vivid, but it surely simply feels oversharpened and you may see the digital noise. The Cat 3 affords a softer and smoother picture. In my preliminary assessment, I questioned the Ratel Professional’s small area of view (FOV) in comparison with typical FPV cameras. Now I start to marvel if Caddx was simply attempting 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 Night time Eagle 3’s low gentle efficiency takes the crown, but it surely solely works in black and white, subsequently it’s much less fitted to daytime flying.
How Effectively FPV Cameras Carry out At Night time?
Low gentle succesful cameras excel at maximizing out there gentle. Their efficiency in low gentle surroundings is measured by a parameter referred to as “LUX.” The decrease the LUX worth, the superior the digital camera’s night time efficiency. Right now, it’s doable to seek out FPV cameras boasting as little as 0.00001 LUX in black and white mode, splendid for night time flying.
Right here’s an instance demonstrating the capabilities of those cameras at night time. Under is how darkish the playground seems to the bare eye or by a normal telephone digital camera:

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

Nonetheless, with out the advantage of a transparent sky and a full moon, or the illumination from close by avenue lights, your digital camera should still 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 digital camera can considerably degrade, leading to noisy and blurry footage that’s troublesome to navigate with. Nonetheless, there’s a sensible answer to this downside.
A method to enhance visibility with out sacrificing the stealth facet of night time flying is through the use of IR (Infrared) LEDs . Not like seen gentle, IR gentle is invisible to the human eye however might be detected solely by digital cameras.
The simplest answer I’ve discovered entails utilizing 48 IR LED boards, which price round £6 (US$8). The one modification required was soldering a feminine stability 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, putting it on high of the quad. This setup is especially handy as a result of it permits for angle changes.
For these with no GoPro mount, take into account the inventive different shared by fellow pilot, Konrad Stepanajtys. He mounted the LED panel on a cardboard field, which then sits on high of the quad.
To stop glare, make sure the LED is positioned away from the digital camera lens.
Not like a bizarre torch, the IR LED doesn’t produce a obvious white spot however as a substitute emits a tender, widespread glow, enhancing visibility with out being obtrusive.
Suggestions for Utilizing a DIY IR Torch:
- Your FPV digital camera should NOT have an IR filter as a way to successfully see the IR gentle.
- Maintain the IR LED at a distance out of your digital camera lens to keep away from reflective glare, which might 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 stability port. If utilizing a 4S or 6S LiPo, a voltage regulator or BEC from the flight controller will probably be obligatory to produce energy appropriately.
Flying Suggestions for Low Mild Circumstances
Black and White Mode: In your FPV digital camera, modify the Day/Night time setting to auto or set it to black and white. This mode supplies higher visibility at night time, lowering digital noise in comparison with colour mode.
Sluggish Down: The lowered visibility inherent to nighttime flying means it’s best to fly slower to permit sufficient time for reacting to obstacles.
Keep Line of Sight: In low gentle circumstances, 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 digital camera feed, retaining your drone inside visible line of sight ensures dependable video transmission and is a essential security observe.
Get a Spotter: Flying with a spotter who can provide you with a warning to approaching individuals or animals you may not see in your goggles can enhance security.
Select an excellent Location: Flying in areas with some gentle sources, reminiscent of close to avenue lights, can considerably enhance visibility at night time.
Add a Self-powered Buzzer and Tracker: To stop shedding your drone, attaching a buzzer with an built-in battery is advisable: https://oscarliang.com/drone-buzzers-with-battery/. A tracker also can assist find your downed drone extra simply.
GoPro Settings for Low Mild: Should you’re capturing your flight with a GoPro, take into account my really useful settings for low-light circumstances, out there right here: https://oscarliang.com/gopro-settings-fpv/#For-LowlightNight-Capturing
Digital camera Comparability in 2018
Again in 2018, I carried out a comparability of a number of low gentle FPV cameras, most of which have since been discontinued. Nonetheless, they could nonetheless be out there second-hand, so I’ve determined to depart the video right here. The cameras had been examined at night time in two areas with totally different ranges of brightness.
On this specific take a look at, the Runcam Night time 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 gentle circumstances. Nonetheless, the Owl did exhibit much less digital noise in testing. Notably, the Eagle provided superior picture high quality through the day in comparison with the Owl, positioning it as a extra versatile “All-Round” digital camera. 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 greatest. But, for low gentle or night time flying, I discovered it unsuitable, primarily on account of a bug within the “Auto Day/Night time” mode that precipitated the display screen to flicker at sure brightness ranges on account of fixed switching between colour and black & white. A useful tip for lowering digital noise in low gentle is to regulate the DNR setting from 0 to 1; I noticed no additional enhancements by rising it past that.
Conclusion
Night time flying with FPV drones affords an unmatched expertise. With the precise digital camera, cautious planning, and adherence to security and rules, pilots can safely discover this difficult but rewarding facet of drone flying. As you enterprise into the night time, keep in mind that thorough preparation and deciding on the precise tools are essential.
