The PTZ-B722 is an outdoor mounting bracket that can be used for CCTV and IP security cameras, security camera housings, outdoor Nema boxes, PTZ cameras and any other device where a flat mounting service is needed for the corner of a building.  This corner bracket is very typically used with the PTZ-H101 PTZ outdoor camera housing.  This housing bracket allows the PTZ-H101 to be mounted on the corner of a building or structure as seen below.  The PTZ-B722 has four pre-drilled mounting holes and a center punch out for cables.  If the existing srcrew holes do not work for your device, many installers use this as a generic corner mount and drill their own holes as needed.
