FI8918 = Excellent; FI9821 = Poor Support/no audio/no HD

I would not buy this app if you purchased a FI9821. It supports this model, but in actuality...extremely poorly. It doesnt support HD video, no one-way or two-way audio support. Many people have requested this feature, but the developer hasnt responded.
