If no joy from the above suggestion, specs infer it's ONVIF compatible. If so, download and run
ODM, put in cam's user/pass into ODM, at the upper part of bottom panel click on "Live View". If it comes up, the RTSP URL is down at the bottom-right. That can be manually inserted in
Blue Iris for the video path if a "find/Inspect" in Blue Iris doesn't work for the cam.
