Swann and Q-see are two rather large OEM's* of security cameras. Swann IP cameras have been rumored to be Hikvision, and Q-see's appear to be Dahuan.
The underlying Hikuan models seem to be ONVIF compatible. If so, a mere fee of $2000/yr, should allow them to recertify these models and claim ONVIF compatibility.
Yet on their websites they act like they have never even heard of ONVIF:
Is this really to their advantage? In addition to the cameras which claim ONVIF but don't deliver it, are there an equal number that deliver without claiming it?
*OEM meaning they are OEM'ing, not that they are the OEM.
