What you need to know before choosing between digital and analog of FPV Goggles
When it comes to FPV systems, there are two basic types to choose from: digital and analog.
Digital: Digital FPV systems use digital signals to transmit video and audio signals, so images are transmitted consistently, with high resolution, and can be transmitted over longer distances.
Analog: Analog FPV systems use analog signals to transmit video and audio signals, resulting in low latency, high real time, and lower prices. Analog systems are more resistant to signal interference and distortion and therefore may be more suitable than digital systems in certain scenarios. Because they are inexpensive and easy to install and maintain, analog systems are a good choice for beginners and drone enthusiasts on a budget.
Some of the more popular brands of digital FPV Goggles on the market today include DJI, HDZero, Fat Shark, Skyzone, Eachine,Among them, DJI’s FPV Goggles have high definition and low latency, can support digital HD video transmission, and have better image stability and a range of advanced features, but the price is higher. Fat Shark is the leader in analog FPV Goggles, offering a range of products for different scenarios and needs. brands such as Orqa, Skyzone, Eachine and Caddx have made some progress in the digital FPV field, offering some more affordable digital FPV Goggles products.
The Best DJI FPV Goggles
DJI’s two main goggle options are the DJI Goggles V2 and DJI Goggles 2. They both support the latest DJI O3 Air Unit.
If you choose the DJI O3 Air Unit, the flight controller can be paired with the MEPS F7 HD Flight Controller.

HDZero is a brand that focuses on quality and performance, providing a high definition and low latency flight experience
Currently, the HDZero series HDZero Explorer also supports direct connection to the DJI O3 Digital Graphic Air Unit
If you are a beginner, here are a few suggestions to choose the right FPV Goggles:
- Latency is a key factor for FPV Goggles because it affects your control and experience. For FPV Goggles, latency includes two aspects: monitor latency and decoder latency. If you want the best FPV experience, you need to choose a product with very low monitor latency and decoder latency. In the market, a latency of less than 20 ms is usually considered a good choice.
- Resolution and Field of View: The resolution and field of view of FPV Goggles is another key factor that will directly affect the quality and range of images you will see during your FPV flight. In general, higher resolution and a wider field of view will provide a better experience. However, it is also important to note that not too high a resolution will result in higher costs and lower frame rates, while an overly large field of view may cause image distortion and eye strain.
- Headwear comfort and quality: Comfort and quality are critical for extended use of FPV Goggles. Choosing a product with an adjustable headband and comfortable eye cups can make you feel more comfortable and relaxed during use. In addition, some high-end brands offer features such as high-quality built-in audio and adaptive adjustments to enhance your experience.
- Other Features: When choosing FPV Goggles, you can also consider other features such as OSD display, support for multiple bands and channels, transparency adjustment, antenna diversity, and more. These features allow you to better adapt to different environments and conditions, and enhance your experience.
Analog FPV Goggles have the following pros and cons:
- Price is lower compared to digital systems, making it a more economical choice for beginners and drone enthusiasts on a budget.
- has lower latency and is more real-time, making it ideal for racing scenarios that require fast response times.
- is more resistant to signal interference and distortion, making it more reliable than digital systems in some scenarios with harsher environments.
The video signal of the analog system is also easier to adjust and can be personalized for different scenarios and personal preferences.
- Image quality is lower compared to digital systems and may be limited in terms of resolution, color, contrast, etc.
- Cannot transmit high-definition video, so it is less suitable for application scenarios that require high-precision images.
- Can generally only operate one UAV on the same frequency band, so it is not possible to control multiple UAVs at the same time.
- Because analog systems use analog signals to transmit video and audio signals, they are more sensitive to signal interference and loss than digital systems and may require some additional interference and interference canceling measures.
- Overall, analog FPV Goggles are suitable for price-sensitive entry-level users as well as speed racers who need faster response times. For those who need higher definition images and more features, a digital FPV system may be the way to go.
Digital FPV Goggles have the following pros and cons:
- Digital system provides higher resolution, better color reproduction and higher contrast, better image quality than analog systems, allowing for clearer and more detailed images.
- Can transmit high-definition video, allowing users to better see the environment and details around the aircraft, making it more suitable for application scenarios that require high-precision images.
- Digital system can control multiple UAVs at the same time, making it more flexible than analog systems.
- Digital systems use digital signals to transmit video and audio signals, which are less sensitive to signal interference and loss and have higher immunity to interference.
- Digital systems typically have more features and setup options, such as video recording, photo taking, intelligent recognition, etc.
- Digital systems are more expensive compared to analog systems and may be out of the reach of some beginners and users on a budget.
- Higher latency may affect the user’s response time, so it may not be suitable for racing enthusiasts.
- Lower resistance to signal interference and distortion, and therefore more prone to problems than analog systems in some scenarios with harsher environments.
Overall, digital FPV Goggles are suitable for users with high requirements for image quality and versatility, especially for applications such as aerial photography and search and rescue scenarios. For entry-level users and racing enthusiasts who need faster response times, analog FPV Goggles are a more appropriate choice.
