Mobotix is starting to come around to its long-term opposition to H.264 and ONVIF.
However, there is another bizarre Mobotix trait - no day/night and worse no integrated IR cameras.
Here's a rambling 9-minute video trying to defend it:
The net/net is that they have black and white imagers (including dual imager cameras) and that they might perform better and have less moving parts (i.e., no cut filter).
Of course, the downside is you are forced to spend significantly more for bulkier dual imager cameras or be forced to choose between only color or only black & white. And in 2015, almost all surveillance users want color during the day.
Worse, literally every camera manufacturer, except for Mobotix, supports integrated IR. Years ago, many premium manufacturers campaigned against integrated IR, but that has long since changed and now it is commonplace.
