62AXIS 241Q/241S - Technical specifications

Frame rates - Motion JPEG

The following test results show the frame rates in frames/second (fps) for Motion JPEG streams from the AXIS 241Q/241S, using a compression level of 50%. Note that these values are guidelines only - actual values may vary.

	AXIS 241Q/241S
	fps (NTSC/PAL)
4CIF	30/25

Frame rates - MPEG-4

The following test results show the frame rates in frames/second (fps) for MPEG-4 streams from the AXIS 241Q/241S. Note that these values are guidelines only - actual values may vary.

The MPEG-4 test conditions:

•Compression level = 50%

•Video Object Type = Advanced Simple

•GOV structure = IP*

	AXIS 241Q/241S
	fps (NTSC/PAL)
4CIF	30/25
2CIF expanded	30/25
2CIF	30/25
CIF	30/25
QCIF	30/25

Note that setting the GOV structure to use “I-frames only” will increase the frame rate.

*The GOV structure can take two different forms; I and IP. The I-structure sends complete images (I-images) whereas the IP-structure mostly sends the differences compared with the previous image (P-images) and only a few I-images. The IP-structure requires much less bandwidth than the I-structure.
