The web interface on the Aprica CCTV DVR is terrible, it requires a proprietary plugin to view video and doesn’t have many of the features I would like.
In the past I’ve played with MotionEye for recording and managing IP network cameras, MotionEye uses motion in the background to get the video streams from the cameras. Unfortunately motion does not support the RTSP protocol or H264 codec used by the CCTV DVR’s web interface.
