If it's ONVIF compatible, you might. The image below allows for the usual setup and at bottom is a place for channel number. It's from the manual for the 7" VTH series. BTW, I don't own either product.
Thanks Tony for the feedback. Tried this but created a user on the HIKVISION and minimum password length is 8 characters, and on the DAHUA the maximum password length that can be entered is 6 characters. Unless there is some modified firmware for the DAHUA monitor. Or else could the DAHUA monitor allow some form of SSH management to create the IPC?
Perhaps. Here's the index to some manuals ==>> here. BTW, I had to use Google Chrome to view, my IE11 may be broken, it stalls & won't finish download of the PDFs.
