For the MJPEG compression mode, the parameters are:
„
Target Bit Rate—(SM4 and MPEG4) The maximum number of bits per second generated
by the device. Valid bit rates range from 9 to 6000 kbps.
„
Target Frame Rate—The maximum number of frames per second (fps) that will be
encoded and transferred by the transmitter. This parameter can be set to 1 to 7, 10, 15,
or 30 fps in NTSC mode and 1 to 6, 8, 12, or 25 fps in PAL mode.
„
Minimum Quantizer—(SM4 and MPEG4) The high video quality boundary. The lower the
value, the higher the video quality and the file size. The value range is from 2 to 31.
„
Maximum Quantizer—(SM4 and MPEG4) The low video quality boundary. A higher
quantizer value means less video quality but a smaller file size. The value range is from
2 to 31.
„
Input Filter Mode—The level of filtering applied to the video signal before it is encoded,
helping to remove high frequency noise from lower quality cameras or noisy video
feeds. The available values are Low, Medium, High, or None.
„
Noise Reduction Filter Mode—The filtering of small variations in pixels in otherwise
motionless sections of the video, to be used in all conditions to reduce the bit rate.
Using this filter also helps reduce the number of false alarms in low light conditions. To
see this parameter, you need to deactivate the second video encoder (see page 45).
The available values are Low (default), Medium, High, and None.
„
Resolution—The measure of how clear and crisp the video image appears. Each
resolution corresponds to a specific number of pixels (columns * lines) for each picture
of the video sequence. The available resolutions are: QCIF, CIF, 2CIFH, 4CIF, All lines,
2/3 D1, and VGA.
