first-person view (FPV) Camera
An FPV camera is a camera designed for first-person view (FPV) applications, such as remote-controlled vehicles and aircraft. FPV cameras are typically lightweight and designed to be mounted on drones, RC cars, and other remote-controlled vehicles. These cameras typically feature wide-angle lenses to capture as much of the environment as possible, and some models also include night vision capabilities. They are usually equipped with an onboard transmitter to send the video feed to a compatible receiver, such as a smartphone or tablet.
FPV cameras like the one you find on the DJI FPV allow you to fly higher and further with some of latest drones being able to fly up to 5 miles away using FPV technology. Military drones or large high-end drones can fly thousands of miles using FPV technology.
This post answers the question of what is FPV camera systems and technologies. Here we explain the latest FPV camera technology on small consumer, commercial and FPV racing drones including CMOS or CCD imaging sensors, Fields Of View (FOV), TVL, Dynamic Range and much more.
There are predominantly 3 main FPV camera sizes:
Standard or Full-sized, Micro-Sized, and Nano-sized cameras. Standard-sized cameras are mostly phased because of their bulky nature and have been replaced by Micro-sized cameras but Standard cameras are still in use today for their robustness and sturdiness.
The FPV (first-person view) camera allows its user to see remotely controlled operations. It is thus used in remotely controlled vehicles or crafts, applied in many fields, but heavily used in applications for security and defense. The benefits of using such technology range from security, through affordability, and to manpower consideration.
When piloting an FPV vehicle, the tester can actually visualize the terrain as if they were physically inside the cockpit. This allows for more situational awareness, sharper detection, and yes, a safer examination process. Should the pilot fail, the only risk is the technology itself and not precious human lives.
The FPV camera offers real-time visuals using a video transmitter. However, the use of a micro FPV camera versus a standard size one allows for the development of more refined technology. It also allows for the creation of customized and adjustable surveillance equipment, unlimited by its size and applications. In short, an FPV micro camera opens possibilities for operation-focused tools that are not only unrestricted by the visualization technology, but are actually elevated thanks to its flexibility.

The benefits are surveyed here, and only some of the reasons why FPV cameras have been growing in popularity for the past few years, and our reliance on them continues to expand.
The FPV system consists of:
- Special antenna to enhance signal quality.
- A transmitter, the power of which determines the radius of propagation of the video signal.
- Power supply unit.
FPV Types: Analog & Digital
When we talk about the transmission of a drone video, it is realized by means of a transmitter and a receiver, and they can operate in different radio frequency ranges – 900 MHz, 1.2 GHz, 1.3 GHz, 2.4 GHz, 5.8 GHz. In the hobbyist niche, the most commonly used bands are 2.4GHz and 5.8GHz. Keep in mind that equipment that is used for data transmission can be digital and analog. Each type has its pros and cons, but one is clearly better than the other. Let’s take a look at each in turn.
The frequency of the receiver and VTX determines the performance of the entire FPV system.
- The highest quality option is 5.8 GHz analog communication. It provides a good signal, suitable for organizing drone races. The standard is used in racing drones, professional FPV systems (Ea chine Assassin 180 ARF).
- Digital signal transmission via Wi-Fi FPV camera at 2.4 GHz is an inexpensive and easy way to exchange information, but the video signal is delayed. The inhibition can be explained by the specifics of the protocol.
The delay is not specified in the model instructions but affects safety during races. If you need a quadcopter with an HD FPV camera for fast flights, then the delay must be determined in advance, otherwise, there is a risk of encountering an obstacle too late.
