PC-CCTV supports ONVIF. PC-CCTV can be controlled by changing setting at the computer where PC-CCTV runs or remotely by means of ODM (ONVIF Device Manager).
The remote control/set up of PC-CCTV program can be very useful since you will be able to make changes of the setting remotely , for example, on the computer near DVR and don't need to be present at the computer where PC-CCTV program runs.
You can check where to download ODM and to see examples on how to use the program on our forum.
