China-based consumer electronics firm Xiaomi, known for its Apple ( AAPL ) copycat smartphones, has come out with a low-cost flying camera drone that could shake up the nascent market. On Wednesday, Xiaomi, roughly pronounced “show me,” introduced its first drone, the Mi Drone, which costs about $380 for the entry-level model with a 1080p camera. A higher-end model with a 4K camera costs about $450. The Xiaomi drones will be sold in China, at least initially, TechCrunch reported . Camera drones from market leader DJI start at $500, with 4K drones starting at $800. And those prices are after recent discounts. Action camera maker GoPro ( GPRO ) is expected to enter the drone market in time for the holiday shopping season. Pricing has not been announced for its Karma drones. U.S. Drone Sales Skyrocketing Retail tracker NPD Group reported Wednesday that drone sales in the U.S. have grown 224% year over year to nearly $200 million in the 12 months ending in April. Drones with 4K cameras accounted for more than one-third of dollar sales in that period, while drones with built-in GPS accounted for 64% of revenue. The average drone sold for more than $550 in April, NPD said. “It’s not surprising that drones were highly sought after during last year’s holiday season,” NPD analyst Ben Arnold said in a statement. “But even after the holidays, NPD’s consumer research indicates drone purchase expectations remain high, especially among younger consumers. This points to continued growth and healthy demand for the category.” China-based DJI was the top U.S. drone vendor in terms of dollar sales. French company Parrot was second, followed by Protocol, Yuneec and 3D Robotics, NPD said.
