Some special cases are:
1. For IP Camera sites, if sub stream is not enabled, the dual streaming
option will be preset and fixed as <Display: Main Stream>.
2. For NVR sites, the recording stream will be whatever streams come in.
The displaying stream will follow rules of dual streaming option selected.
3. For VSS/NVR sites, the dual streaming options will not be available if the
connection type is set to <Sub Stream Only>. Thus both recording and
displaying streams will be the sub stream.
