SD Range
Quick Overview Of Default SD Record Settings
SD units provide out of the box:
High performance recording on ALL cameras with minimal configuration.
Consistent recording duration and smooth motion video per camera regardless of the number of
cameras.
The product range has Normal, Medium and Low record rate models.
Normal
Continuous 5pps MPEG4 recording on all cameras, on all channel variants (default out of the box).
Medium
Continuous 2pps MPEG4 recording on all cameras, on all channel variants (default out of the box)
Low
Continuous 1pps MPEG4 recording on all cameras, on all channel variants (default out of the box)
Complete Flexibility
The picture quality can be increased if less than 30 or 60 days standard recording is required.
The advanced record menu can be used to configure individual cameras to suit specific
requirements e.g. Entry/Exit routes. Various storage sizes are available dependant on the
combination of the number of cameras, the 30 or 60 day storage options, and the Normal, Medium
and Low record rates selected.
With Global record rates of up to 100pps (PAL) and 120pps (NTSC), the SD Range offers recording
of up to 5pps on each camera, out of the box, at a record duration of 7, 14, 30 or 60 days (the
default is 14 or 30 days depending on variant).
Note:
It is the Installer/Owner’s responsibilty to ensure that the record duration is set to the
necessary requirements of the application.
Multi
Mode
Recording
The unit supports
Multi
Mode recording, which is a storage technology developed by Dedicated
Micros. This offers the ability to set different recording rates, resolutions and compression formats
across scheduled, normal and alarm modes for each individual camera.
By varying the quality, bit rate and file size of the recorded images, the
Multi
Mode function can
increase recording capabilities of the unit.
Multi
Mode
offers:
Ability to set different recording resolutions.
Ability to set and switch MPEG or JPEG compression recording as required.
Ability to set PPS recording rate per camera.
Dynamically switchable resolution when switching from Normal to Event recording.
Dynamically switchable compression between MPEG4 and JPEG from Normal to Event
recording.
Differences between MPEG-4 and MJPEG(JPEG)
JPEG (short for Joint Photographic Experts Group) is an ISO/IEC standard algorithm for the
compression of digital still images. It can reduce files sizes to five percent of the original size
although some detail is lost at that level of compression. Ratios of 10:1 to 20:1 may provide little
noticeable loss. The more the loss can be tolerated, the more the image can be compressed.
