This results in approximately 15 Gb per day per camera of video files. I found that the optimal bitrate is 2 Mbit: going to 4 only meant that the files were twice the size without any noticeable improvement of the quality. In the cameras’ settings you can choose the video bitrate, up to 4 Mbit. I started digging around, and I found that ffmpeg could easily record the RTSP stream from the cameras. The onboard firmware allows to record to an FTP server, but this was suboptimal, there was no easy way to define the clip length and was pretty clunky to set up.
One thing I wanted, though, was having the footage from the last 1-7 days available at any time. I’ve had a couple of Foscam FI9805W H264 IP cameras for almost a year, and I’ve been very happy with them: the 1280×960 image is sharp and clear both during the day and during the night, and their firmware has been very reliable.
