Constant Frame Rate (CFR):This mode maintains the target frame rate. Video
quality may suffer and the bit rate may exceed the target value.
Quantizer Control Mode:
Standard:
High on Motion Area:
Resolution:The total number of lines (width × height) in the video image. The greater the
number of lines produces a more detailed, clearer and sharper image, but requires more
bandwidth and storage. The following resolutions are available:
CIF: NTSC (352 × 240) and PAL (352 × 288)
2CIF: NTSC (704 × 240) and PAL (704 × 288)
4CIF: NTSC (704 × 480) and PAL (704 × 576)
D1: NTSC (720 × 486) and PAL (720 × 576)
Compression Mode:This parameter cannot be changed. The compression mode column
displays the method of encoding currently being used on the Edge device. For the multiport
devices, encoders 1 and 2 are set to H.264 and encoder 3 is set to MPEG4. For the
single/dual devices, encoders 1, 2 and 3 are set to H.264 and encoder 4 is set to MJPEG.
NOTE: For devices running analytics and the S1816e-SP and S1816e-SRmodels running
in single or legacy mode, only two streams are available. In this case, Encoder 1 is
set to H.264 and Encoder 2 is set to MPEG4.

Video Profile
Video Profiles define both the quality of the video images and the storage and bandwidth
requirements of the video files. All Video Profiles include at least the following settings: frame rate,
resolution, and bit rate. For each video input, you can configure the image parameters. With each
video input, the S1800e series devices supports up to quad-stream encoding (triple-stream
encoding on the multiport devices and quad-stream encoding on the single/dual port devices).
Encoding the video inputs provides multiple live-view streams using different sets of parameters
providing high or low quality video for analysis and a single recording stream using H.264 video
compression providing high quality video at a substantially lower bit rates than previous standards.
NOTE: Nextiva video management software currently supports a maximum of two streams and
provide four video profiles for the S1800e series devices. For more information configuring
video profiles, refer to the Nextiva VMSAdministrator Guide.
