The Phantom 4 Pro comes with a 20-megapixel camera capable of shooting 4K video at 60 fps. On the other hand, the Phantom 4 V2 has a 12-megapixel camera which shoots 4K video at 30 fps. So, if you prioritize higher resolution and smoother video quality, the Pro version might be the better choice.
The Phantom 4 Pro features Lightbridge HD video transmission with a 4.3mi (7km) range, providing a more reliable and stable connection for your drone. Meanwhile, the Phantom 4 V2 uses OcuSync 2.0 transmission technology, giving it a similar range but with enhanced interference resistance. This makes the V2 model more suitable for areas with high wireless interference.
When it comes to flight time, the Phantom 4 Pro can stay airborne for up to 30 minutes on a single charge, while the Phantom 4 V2 offers slightly less at around 28 minutes. If longer flight sessions are crucial for your needs, the Pro version would be the preferable option.
