ITB-100HD was one of my favourite ones and still is in point of design, but it looks like because of poor R&D they are in so called race to the bottom.
Even with their (old?) new ITB-100SPW (WiFi ) model, they have not progressed other than WiFi. Bit-rate is very low, only 6.5mbps
Note: DVR menus and voice is currently in Korean.... there is no English firmware as yet.
Apple-ct is now selling the full black version of the ITB-2000HD... drop apple-ct an enquiry mail. As for Itronics product availability, I noticed apple-ct set the website to display the Itronics products on random days.
