Dimension and Weight

FPV digicam sizes are decided by the width, which is the space between the mounting holes on each side. Your selection of digicam measurement depends upon your FPV drone body and the way you intend to mount it. The frequent sizes embrace:

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

Micro measurement is the preferred lately, because it sometimes works effectively with fashionable 3-inch, 4-inch, and 5-inch frames (and bigger). Drones which can be smaller typically use the Nano measurement. You’ll want to 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 (subject of view), which is beneficial when your drone tilts ahead or backward whereas rushing 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, if you happen to 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 digicam. Mismatched facet ratios can lead to distorted photos within the goggles. As an illustration, you probably have a 4:3 digicam and 16:9 goggles, the picture will seem stretched.

Some FPV cameras permit you to change between 4:3 and 16:9 facet ratios. Nonetheless, when switching to a non-native facet ratio, you’ll expertise a lowered FOV resulting from cropping. It’s greatest to make use of the native facet ratio of the digicam for optimum efficiency.

Area of View

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

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

There isn’t any “greatest” FOV, because it in the end depends upon private desire and the kind of setting wherein you fly.

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

Lens Focal Size Approx. FOV
1.8mm 160° – 170°
2.1mm 150° – 160°
2.3mm 140° – 150°
2.5mm 130° – 140°
2.8mm 120° – 130°
3.0mm 110° – 120°

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

Huge Dynamic Vary

WDR - Wide Dynamic Range of an FPV Camera

The Huge Dynamic Vary (WDR) of an FPV digicam determines the picture high quality in excessive lighting situations the place each vibrant and darkish areas are current in the identical body. A superb digicam ought to ideally enable the pilot to see as a lot element within the shadows as doable whereas stopping the sky from being overly overexposed. Selecting an FPV digicam 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.

Low Mild Efficiency

Picture Sensor Dimension

Along with CCD and CMOS varieties, picture sensors additionally come in several sizes. The 2 common sensor sizes for analog cameras are 1/1.8″ and 1/3″, with the previous being bigger and the latter being smaller.

Sensor measurement influences low mild efficiency and dynamic vary. Typically, a digicam with a bigger sensor can have higher low mild efficiency below the identical settings. Moreover, a bigger sensor offers a wider subject of view (FOV) when utilizing the identical focal size lens.

Digital camera Lens

You’ll be able to substitute the lens on an analog FPV digicam to attain a unique FOV or picture high quality. FPV digicam lenses primarily differ in two elements: focal size and thread measurement. For extra in-depth info, you’ll be able to confer with our article particularly about FPV digicam lenses.

Full-size cameras sometimes use bigger and heavier lenses with 12mm diameter thread that may be screwed into the housing, referred to as M12 lenses. Smaller 8mm lenses, or M8 lenses, are utilized to make cameras extra compact and light-weight. M12 lenses enable extra mild in, leading to marginally higher picture high quality in comparison with M8 lenses. M8 lenses are extremely compact and are principally utilized in Micro and Nano cameras.

NTSC and PAL

The principle distinction between NTSC and PAL lies of their decision and body price. PAL (720 x 576 @ 25fps) presents barely higher decision, whereas NTSC (720 x 480 @ 30fps) offers the next body price. For those who choose higher image high quality, select PAL; in order for you smoother footage, go for NTSC. For a extra detailed comparability, try this put up.

Historically, NTSC is utilized in North America, Japan, and South Korea, whereas PAL is employed in most of Europe, Australia, and huge elements of Africa and Asia. It may be a good suggestion to stick to the usual in your nation. Nonetheless, that is much less of a priority these days, as each video codecs are absolutely supported by all FPV gear.

Keep in mind to pick the suitable format your digicam makes use of in Betaflight OSD to make sure that the textual content is displayed appropriately.

TVL

TVL, or “TV strains,” is the time period utilized by producers to measure the decision of analog FPV cameras.

TVL is measured by connecting the digicam to a show and having it seize a picture of a card with alternating black and white strains. The utmost variety of distinct black and white strains that the digicam can detect is its TVL worth, which represents the picture element the digicam is able to producing.

Nonetheless, TVL has turn out to be much less significant in recent times, as producers usually inflate these numbers as a advertising software. As an alternative of counting on TVL, select your digicam primarily based on the picture high quality demonstrated in opinions.
