Question: Which method is better to use this USB camera on an iPhone and iPad, WiFi box or a U2i adapter?

Answer: We recommend the U2i adapter method based on the following reasons: 1. The U2i adapter is a physical cable connection. The signal is more consistent and sturdy. 2. With a U2i adapter, the video has almost no lapse, not like a wifi box, especially if you choose a high 2MP resolution. 

A wifi box will work with the USB microscope and iPhone / iPad. However, the wireless signal transmission is not fast enough for 2MP camera sensor at 30 fps.
