You can select MPEG4 or MJPEG as the video format. It is recommended to select
MPEG4 for real-time browsing to optimize the bandwidth. MJPEG is a good choice for
the best resolution when video recording is required for collection of evidence.
Sensor Scan Mode: SXGA model will scan all sensor pixels (1.3 mega-pixels) and then
output; while VGA mode will scan all sensor pixels and scale down into VGA (640 × 480)
then output. Under the SXGA mode, the total frame rate (FPS) of MPEG4＋MJPEG can
achieve up to maximum 15fps, and 3GPP is not supported under this mode, For example, if
the total frame rate of MPEG4 and MJPEG is set to 15fps, each video encoder will reach 8fps
approximately. Under the VGA mode, the frame rate can reach 30fps for each video encoder
and 3GPP is supported, too.
Dual video encoders: Under SXGA mode, the primary video encoder is MPEG4, and the
secondary encoder must be MJPEG. On the other hand, under VGA mode, the primary video
encoder is MPEG4 while the secondary can be either MJPEG or MPEG4.
