Below are new features of Phantom 4 Pro V2.0 compared to original Phantom 4 Pro:
OcuSync With 1080/30 Video Link
The main evolution is the introduction of the OcuSync radio transmission technology on the Phantom family that previously used the Lightbridge 2 system. In real life, the range and latency should be improved over the older Phantom models. The downlink stream is now able to display video in 1080/30 fps against 720/30 fps previously.
New Remote Rontroller Not Compatible With the Phantom 4 Pro
Due to the adoption of the OcuSync technology, the older Lightbridge controllers won’t be compatible with the V2.0.
New Powertrain and Quieter Propellers
DJI fitted new motors and ESCs on the V2.0 with new propeller profiles (like the Mavic Air Platinum). According to DJI, these 9455S propellers are up to 60% quieter (4dB) than the regular propellers. Older propellers can still be mounted on the new Phantom, while the 9455S model are compatible with the regular Phantom 4 Pro version.
Increase Range of the Anti-Collision Sensors.
The anti-collision system remains the same, but DJI extended the detection range of the forward and backward-sensing system to 90 feet (30 meters) instead of 30 feet (10 meters).
