AXIS 212 PTZ - Video Streams

Video Streams

The AXIS 212 PTZ provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 212 PTZ provides access to MPEG-4 and Motion JPEG video streams, as well as to single JPEG images. Other applications and clients can also access these video streams/images directly, without going via the Live View page.

How to stream MPEG-4

This video compression standard makes good use of bandwidth, and can provide DVD-quality video streams at less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients.

Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The available options in AMC are:

Unicast RTP	This unicast method (RTP over UDP) should be your first consideration for
	live video, especially when it is important to always have an up-to-date
	video stream, even if some images are dropped.	Unicasting is used for video-on-demand broadcasting, so
RTP over RTSP	This unicast method (RTP tunneled over RTSP) is useful as it is relatively	that there is no video traffic on the network until a client

		Note: There is a maximum of 20 simultaneous viewers.
RTP over RTSP over HTTP	This unicast method can be used to traverse firewalls. Firewalls are
	commonly configured to allow the HTTP protocol, thus allowing RTP to
	be tunneled.
Multicast RTP	This method (RTP over TCP) should be your first consideration for live	Multicasting provides the most efficient usage of

		multicast broadcast cannot pass a network router unless
		the router is configured to allow this. It is thus not
		possible to multicast over e.g. the Internet.

AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed above. This order can be changed and the options disabled, to suit any specific requirements. Right-click the video image and select Settings from the menu to access the AMC menu.
