O4 air unit.

Thats the Transmision system NOT the air unit, The O4 air unit is for us builders who want to add O4 to our Drones.
The dji O4 video transmission system is not the same as an Air Unit. see below:

O4 OR Occusync 4 is DJI's Transmission codec for Drones.....There are Many different ones used by others: O4, Walksnail, HD Zero, as well as others. DJI Drones use the Occusync system it is their proprietary Video Transmission Method. All DJI Drones introduced from this time on will use Occusync 4 (or O4) until they come up with the next one lol

You meant 04 Occusync, I think. I don't know which others have it currently. I'm sure the upcoming Mavic 4 Pro will have it...or 05 for all I know. I'm confident any drones marketed this year will have it or something even newer. It's why my current RC Pro controller will almost for sure NOT work with the upcoming Mavic 4 Pro....

DJI uses the Occusync system to transmit video to your controler or goggles, DJI sells The AIR UNIT for those who wish to use our DJI goggles or controllers with our home builds.
If i want to build a drone that will be compatible with my DJI goggles and controller I will put an air unit in it, like the one below.

To make it more clear (for me). What are the differences between the Occusync 4 and the O4 Air Unit? Aside from the form factor.
I like the specs on the O4 Air unit and I am trying to compare the two similar but difference electronics.
Edit. If I am going to get a brand new drone, I would like it to have the latest tech (that I can afford). If I go with a drone from the classified section, then I am expecting to give up cutting edge electronics for saving money.
I asked Grok. Straight up copy and paste.
To compare Occusync 4 with the O4 Air Unit, we need to clarify that these terms refer to different aspects of DJI's FPV (First-Person View) technology:
- Occusync 4 is DJI's video transmission technology, a protocol used for sending video from the drone to the goggles or controller with high quality, low latency, and a robust connection. It's the current iteration in DJI's line of transmission technologies, providing enhancements over previous versions like O3 in terms of range, latency, and video quality.
- O4 Air Unit refers to the physical device (the video transmitter and camera module) that you would integrate into a custom or DIY FPV drone build. This unit leverages the Occusync 4 technology for its video transmission capabilities.
Here's a comparison based on the available information:
### Occusync 4:
- Technology: Video transmission protocol.
- Features:
- Range: Increased range compared to previous versions, with capabilities up to 15 km in FCC mode for the O4 Air Unit.
- Latency: Extremely low latency, around 15 ms (milliseconds) for the O4 Air Unit Pro, enhancing the real-time feel of flying.
- Video Quality: Supports 4K video recording at up to 120 fps, delivering high-quality live video feeds.
- Compatibility: Works with DJI's latest FPV systems, including goggles like the Goggles 3 or N3, enhancing user experience with features like D-Log M for better post-processing.
- Frequency Bands: Utilizes multiple bands, including 2.4 GHz, 5.8 GHz, and sometimes 5.1 GHz for better penetration and less interference.
### O4 Air Unit:
- Physical Device: A modular component for FPV drone builds.
- Variants:
- O4 Air Unit Pro:
- Dual antennas for better signal coverage.
- 4K video recording at 120 fps.
- Larger image sensor (1/1.3") for better low-light performance.
- Capable of recording in D-Log M format.
- Supports microSD cards for expanded storage.
- Advanced features like Auto mode for power management, manual power adjustments, and Race Mode for even lower latency.
- O4 Air Unit Lite:
- Designed for smaller, lighter FPV setups like micro drones or whoops.
- Single antenna, still offering 4K at 60 fps, but with a smaller sensor (1/2") than the Pro.
- Lighter and less power-intensive but with compromises in image quality and low-light performance compared to the Pro.
- Compatibility: Both versions are compatible with DJI FPV systems, specifically the newer goggle models that support Occusync 4. They work with external radio systems like ELRS, TBS Crossfire, and FrSky, giving builders flexibility in control options.
- Design: Both units are designed for easy integration into custom drone builds, with standard mounting patterns and cable setups.
### Key Differences:
- Purpose: Occusync 4 is the technology behind the transmission, while O4 Air Units are the hardware implementations of this technology.
- Performance: The O4 Air Unit Pro offers top-tier performance for larger or more professional setups, while the Lite version caters to those looking to maintain high performance in smaller, lighter drones.
- Build and Use: The Air Unit's physical attributes like size, weight, and antenna configuration affect how they're used in drone construction, whereas Occusync 4 speaks to the capabilities of the transmission tech itself.
In essence, choosing between Occusync 4 and an O4 Air Unit isn't a direct comparison but rather understanding how the technology (Occusync 4) is implemented in the hardware (O4 Air Unit). If you're building or upgrading an FPV drone, deciding between the Pro or Lite version of the O4 Air Unit would depend on your drone's size, your performance needs, and the trade-offs in terms of weight, size, and image quality.

Thats it ...sorry, The 04 air unit is an actual "device" that uses O4 to transmit video just like a DJI Drone,..... However DJI Drones do not use Air units, Their VTX's (video Transmitters) are built in to the Drone.
If you are going to use the drone for photos and videos you might want the latest, but as a casual hobbist or simply a pilot who flys for the enjoyment of it, You dont need to spend the money on the latest tech.

Agreed. If I’m buying new, with retail pricing, I want to make sure I’m getting the latest tech.
Doing my homework.
Currently I have 2 drones. One from DJI and one from Autel. At a certain point they are worth selling to put the money toward a new drone. Then they quickly go from that to may as well fly them until they crash.

The real problem here, which nobody noted, is DJI's incredibly stupid product naming decision.
All this confusion was created by DJI.
