4.2 General configuration information
■ Configure your system with all cameras connected and all final camera
perspectives set, for best results. This enables precise calculation of images
sizes detected in SmartDisc 10IP configuration mode.
■
If possible, use conditional refresh mode (differential image compression).
This method is more efficient than the option single image compression.
SmartDisc 10IP only records conditional refresh images if the interval
between two consecutive images is not greater than 10 seconds. For larger
intervals, significant image changes are assumed and therefore full image
recording is activated. The advantages of conditional refresh mode are:
■
The available storage capacity is used more efficiently. This increases
the period available for recording images.
■
Recording speed is increased.
■
Online evaluation is faster. This is of advantage when using narrow
bandwidth communication paths such as GSM, MODEM, or ISDN.
■
It is additionally recommended on analogue video signals to Record
preview images if the evaluation is to be made over narrow bandwidth
communication channels such as GSM, MODEM, ISDN.
■
Camera noise, e.g. caused by poor lighting, can cause excessively large
images, even in conditional refresh mode - factory setting - as camera
noise is interpreted as image change.
■ Image quality can be set separately for each camera input, and for image
transmission and image recording. Additional options for resolution and
multi image display mode are available for image transmission. Full format
live transmission allows adjusting resolution by the viewer during
transmission.
■
If you want to control recording on several cameras using movements, i. e.
the integrated motion detection on analogue cameras, consider using
external motion detectors. The integrated motion detection is not desi-
gned for outdoor recordings and should therefore be reserved for indoor
cameras. This avoids false alarms.
■ The integrated motion detection for analogue cameras allows you to set
different levels of sensitivity for controlling recording and alarm forwarding
to a SmartControl station
■
When defining the pre-alarm and post-alarm sequence, please note that
new messages generated during an event (e.g. caused by alarm contacts
or the integrated motion detection) on analogue cameras will be ignored
at first and will only be processed after the post-alarm time or after the
adjustable retrigger time has elapsed.When defining pre-alarm and post-
alarm sequence: New messages generated during an event (e.g. caused by
alarm or motion detection) will be ignored at first and will only be
processed after post-alarm time or after adjustable retrigger time is up.
■
The number of events will be reduced by the frame storage device if
storage space allocated to any camera for any single event is less than
3 MB.
■
The device gives highest priority to image recording triggered by input
state change, i.e. when recording via Edge + or Edge – is enabled. If the
device has detected a change on a control input, it will interrupt recording
triggered by a different status, by status change or (on analogue cameras)
