NOTE:
is a mechanism that limits the lifespan of data in a computer or network.
TTL
Image size: select the desired resolution: 1280x1024, 1280x720, 640x480 or 320x240.
Frame rate: select the desired frame rate per second. Depending on selected resolution,
the following values are supported: 2, 3, 4, 5, 7, 10, 15, 20, 25 and 30 frames per second. For
1280x1024 or 1280x720 resolution, the following frame rate values are supported: 2, 3, 4, 5, 7, 10,
and 15. For 640x480 or 320x240 resolution, the following frame rate values are supported: 2, 3, 4,
5, 7, 10, 15, 20, 25, and 30.
NOTE:
To use a frame rate value higher than 15, set a resolution not higher than 640x480 for Н.264/MPEG-
4/MJPEG streams.
Quality: choose an option for the video quality of the video stream from the camera.
 Auto: the camera automatically adjusts the image quality and the frame rate according
to available bandwidth. In low-bandwidth conditions, the camera automatically reduces
video streaming rate and leaves the frame rate unchanged.
 Fixed quality: set the video quality to: [Excellent], [Detailed], [Good], [Standard], and
[Medium].

Fixed bitrate: set the video bitrate to a fixed value: 64, 128, 256, 384, 512, 768 kbps
and 1, 1.5, 2, 3, 4, 5, 6 Mbps.
IP interval: a numerical relation between i-frames and p-frames. The following values are
available: 1, 5, 10, 15, 30, 60, 120 and Auto. The less the value, the better the image quality and
the more bandwidth is required for video streaming. It determines, how many p-frames should be
sent before another i-frame (or a key frame) is sent.
NOTE:
If H.264 is selected in SETTING – Basic – Camera – General, the [IP interval] becomes unavailable and
the numerical relation between i-frames and p-frames sets to [Auto] (the camera automatically sets the
value).
