Any chance of adding Anpviz camera profile so we can use 2 way audio with SecuritySpy? That would really make it ideal. I can use other profiles or ONVIF but those do not support 2 way audio with Anpviz cameras.
It's possible, but firstly, could you please try both the Dahua and Hikvision profile in turn, to see if either of these work with your cameras? Many cameras are rebrands of products from these companies - I'm not sure if Anpviz are, but it's certainly worth a try.
Some Anpviz are indeed Hikvision OEM cameras but from what I can they have available in the UK many appear to be their own ‘generic’ Chinese units.
