Here's a few specifications:
- Ambarella AL7S SoC (same as the GoPro Hero3+ Silver)
16.0MP Sony Exmor R BSI CMOS image sensor
F2.8 aperture and with 155°wide angle
Broadcom wireless chipset with both WiFi and Bluetooth 4.0
It can shoot video at 1080p at 60fps and 720p at 120fps. It's 16MP Sony CMOS sensor is I can only assume better than the 10MP Hero3+ Silver's sensor. So on paper it matches or exceeds any GoPro from a video/resolution perspective up to the Hero3+ Silver. Unlike that camera though, it's price point isn't $430, it's $110 (with free shipping).
All that gushing aside it is definitely not a bells and whistle camera. It has no screen and only 3 buttons (power, shutter, wifi). To configure it you need to use an Android phone and the Yi app which apparently is still partly in Chinese. There's a Bluetooth remote in the works apparently but it's not yet on the market. Still, 1080p60 at $110? I hope to receive mine before our Grass Valley launch at the end of this month.
Here's a review from cnet
I ordered mine from the awesomely named banggood.com
I'll post some footage on YouTube in the near future and update this thread with the results.
