8-channel DVR. This device uses AHD cameras which are a type of HD over coax. Should only be used for existing coaxial. Is reportedly compatible with older analog cameras as well.
The user manual for this DVR reports a stream accessible at rtsp://<user>:<pass>@<ip>:554/A/B Where A=01(ch1), 02(ch2) B=0(mainstream),1(substream)
Note that this has not been tested in practice, but is likely to work. RTSP may need to be enabled.
