Recording directly to a MOBOTIX camera while certainly convenient, can be a big time hog.  Mobotix uses their own MxFS files system that is more fault tolerant then Fat32 or NTFS and thus the cards must be formatted.  A format to a 128GB card can take several hours.  ABP now carries 64 and 128GB preformatted microSD cards at quite competitive prices to save you time and thus money.
