Analog
Dimension and Weight
FPV digital camera sizes are decided by the width, which is the space between the mounting holes on each side. Your alternative of digital camera dimension depends upon your FPV drone body and the way you propose to mount it. The frequent sizes embrace:
- Normal, aka “full dimension” (28mm)
- Mini (21mm)
- Micro (19mm)
- Nano (14mm)
Micro dimension is the preferred as of late, because it usually works nicely with fashionable 3-inch, 4-inch, and 5-inch frames (and bigger). Drones which are smaller usually use the Nano dimension. Be sure you double-check the specs of your body to verify 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 well-liked for FPV flying as a result of it supplies extra vertical FOV (area of view), which is beneficial 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 data 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 digital camera. Mismatched facet ratios may end up in distorted photographs within the goggles. As an example, when you have a 4:3 digital camera and 16:9 goggles, the picture will seem stretched.
Some FPV cameras help you change between 4:3 and 16:9 facet ratios. Nonetheless, when switching to a non-native facet ratio, you’ll expertise a decreased FOV because 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 helps you to see extra of the setting, which could be most well-liked for proximity flying and racing.
Nonetheless, when the FOV is just too giant, 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 sides of the picture seem curved and distorted.
There is no such thing as a “finest” FOV, because it in the end depends upon private choice and the kind of setting 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:
| 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 have an effect on FOV if the digital camera 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.
Extensive Dynamic Vary
The Extensive Dynamic Vary (WDR) of an FPV digital camera determines the picture high quality in excessive lighting situations the place each vibrant 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 doable whereas stopping the sky from being overly overexposed. Selecting an FPV digital camera with respectable 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

- Much less picture processing and digital artifacts, nonetheless decision and picture element often seem decrease than the perfect CMOS cameras
- Above common efficiency in low gentle, dynamic vary and light-weight/darkish transition
- Higher picture distinction than CMOS
- CCD cameras carry out equally throughout the board, not like CMOS cameras with various efficiency
CMOS:
- Extra inclined to jello because of rolling shutter
- Various efficiency and worth: the costliest cameras are often CMOS, and sarcastically, the most cost effective cameras are additionally CMOS, whereas CCD is usually within the mid-price vary
- Usually decrease in latency
- Increased decision and sharper picture, with the trade-off of doubtless over-sharpening and digital artifacts
- Low gentle/night time FPV cameras have a tendency to make use of giant CMOS sensors
- Normally extra versatile/dynamic with digital camera settings
Picture Sensor Dimension
Along with CCD and CMOS varieties, picture sensors additionally come in numerous sizes. The 2 widespread sensor sizes for analog cameras are 1/1.8″ and 1/3″, with the previous being bigger and the latter being smaller.
Sensor dimension influences low gentle efficiency and dynamic vary. Usually, a digital camera with a bigger sensor can have higher low gentle efficiency underneath the identical settings. Moreover, a bigger sensor supplies a wider area of view (FOV) when utilizing the identical focal size lens.
Digicam Lens
You’ll be able to substitute the lens on an analog FPV digital camera to attain a special FOV or picture high quality. FPV digital camera lenses primarily differ in two points: focal size and thread dimension. For extra in-depth data, you may confer with our article particularly about FPV digital camera lenses.
Full-size cameras usually use bigger and heavier lenses with 12mm diameter thread that may be screwed into the housing, generally known as M12 lenses. Smaller 8mm lenses, or M8 lenses, are utilized to make cameras extra compact and light-weight. M12 lenses permit extra gentle 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 charge. PAL (720 x 576 @ 25fps) presents barely higher decision, whereas NTSC (720 x 480 @ 30fps) supplies a better body charge. For those who choose higher image high quality, select PAL; if you would like smoother footage, go for NTSC. For a extra detailed comparability, take a look at this submit.
Historically, NTSC is utilized in North America, Japan, and South Korea, whereas PAL is employed in most of Europe, Australia, and enormous components of Africa and Asia. It could 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 totally supported by all FPV gear.
Keep in mind to pick out the suitable format your digital camera makes use of in Betaflight OSD to make sure that the textual content is displayed accurately.
TVL
TVL, or “TV traces,” is the time period utilized by producers to measure the decision of analog FPV cameras.
TVL is measured by connecting the digital camera to a show and having it seize a picture of a card with alternating black and white traces. The utmost variety of distinct black and white traces that the digital camera can detect is its TVL worth, which represents the picture element the digital camera is able to producing.
Nonetheless, TVL has turn into much less significant in recent times, as producers usually inflate these numbers as a advertising and marketing instrument. As a substitute of counting on TVL, select your digital camera primarily based on the picture high quality demonstrated in opinions.
