Measurement and Weight

FPV digital camera sizes are decided by the width, which is the space between the mounting holes on each side. Your selection of digital camera dimension relies on your FPV drone body and the way you propose to mount it. The widespread sizes embrace:

• Normal, aka “full dimension” (28mm)
• Mini (21mm)
• Micro (19mm)
• Nano (14mm)

Micro dimension is the most well-liked today, because it usually works properly with fashionable 3-inch, 4-inch, and 5-inch frames (and bigger). Drones which are smaller typically use the Nano dimension. Make sure you double-check the specs of your body to substantiate compatibility and keep away from surprises.

Facet Ratio

There are two facet ratios to select from in FPV cameras: 4:3 and 16:9.

4:3 is most popular for FPV flying as a result of it offers extra vertical FOV (discipline of view), which is helpful when your drone tilts ahead or backward whereas dashing up or slowing down. This lets you see what’s in entrance of you extra clearly. In distinction, 16:9 presents a wider view on the edges, however that info is much less helpful for pilots.

Moreover, when you plan to stabilize your footage utilizing software program like Gyroflow, 4:3 has an edge over 16:9 as a result of it crops much less of the picture when rendering right into a 16:9 video for importing to platforms like YouTube.

Ideally, your FPV goggles ought to help the facet ratio of your FPV digital camera. Mismatched facet ratios may end up in distorted photos within the goggles. As an illustration, if in case you have a 4:3 digital camera and 16:9 goggles, the picture will seem stretched.

Some FPV cameras can help you swap between 4:3 and 16:9 facet ratios. Nonetheless, when switching to a non-native facet ratio, you’ll expertise a diminished FOV on account of cropping. It’s finest to make use of the native facet ratio of the digital camera for optimum efficiency.

Discipline of View

The sphere of view (FOV) of an FPV digital camera determines the angle of the captured picture. A smaller FOV leads to a extra zoomed-in picture, permitting you to see obstacles like branches extra clearly. A wider FOV permits you to see extra of the atmosphere, which is likely to be most popular for proximity flying and racing.

Nonetheless, when the FOV is just too massive, the picture seems distorted, leading to so referred to as “fish-eye” impact. Objects within the heart would seem smaller and additional away than they’re in actuality, whereas the perimeters of the picture seem curved and distorted.

There isn’t a “finest” FOV, because it in the end relies on private desire and the kind of atmosphere wherein you fly.

FOV is affected by the lens’s focal size and the picture sensor dimension. A shorter focal size and a bigger sensor dimension lead to a wider FOV. Right here’s a tough estimation of FOV for a digital camera with a 1/3″ sensor dimension in 4:3 facet ratio:

As talked about beforehand, facet ratio may have an effect on FOV if the digital camera helps each 16:9 and 4:3. On this case, choosing a non-native ratio will merely crop the edges or the highest and backside, leading to a smaller FOV.

Huge Dynamic Vary

The Huge Dynamic Vary (WDR) of an FPV digital camera determines the picture high quality in excessive lighting circumstances the place each brilliant and darkish areas are current in the identical body. digital camera ought to ideally permit the pilot to see as a lot element within the shadows as attainable whereas stopping the sky from being overly overexposed. Selecting an FPV digital camera with first rate WDR functionality is essential, because it helps you see higher whereas flying, in the end serving to you keep away from obstacles and crashes.
