H.264, MPEG4, MJPEG are true full motion video with audio.
Internet browsers (IE, Safari, Chrome, Firefox, Opera…) typically cannot show this without an add-on program.
On PCs with IE7/IE8 the required add-on program (also known as ActiveX) is installed and activated automatically
if you click” Enter” on the camera’s main login screen.
On Mac and IOS device with the Safari browser, the camera defaults to “ RTSP H.264 stream” and “HTTP M3U8
stream”( HLS stream, HTTP Live Streaming), so the camera can directly stream audio and video on Safari browser
with http://xxx.xxx.x.xxx camera IP address.
On Linux computers the browser defaults to “HTTP MJPEG Stream” and you can see H.264/MPEG4 streaming
video and audio with a media player such as VLC if you open the RTSP stream for H.264, MPEG4, MJPEG.
On Google Chrome and Firefox browser, the camera defaults to “HTTP MJPEG Stream” with Video only.
MJPEG is Motion JPEG, basically a very quick sequence of images that resembles full motion video. However
MJPEG has no sound and therefore on Linux computers you would use the media player (such as VLC) instead of
the browser to access your camera if you want audio. The JPEG snapshot image is handy when you don’t want
video or audio and just want a current picture.
