Specs say ONVIF, try running
Onvif Device Manager; if it comes back as Qvis, look at the MAC address revealed by ODM, copy it, go
here and paste it in, select "Lookup Vendor".
I have an Amcrest that I know is made by Dahua, ODM says nothing but Amcrest, I copied the MAC address and pasted into the above site, selected "Vendor Lookup" and it came back as "Dahua."
BUT.....
I have an 8 year old Trendnet IP cam that's not ONVIF; I put in the MAC address, got nothing on "Vendor Lookup", selected this time "Lookup MAC address" and it came back "Trendnet".
It's not a sure thing but you might get lucky and know more than you know now.
