Pre-play storage
Unlike flexible PC systems, embedded recorders have a
hardware configuration which is tailored to their intended
purpose. As a consequence, the desired recording
schedule cannot always be achieved in the special case
of pre-play recordings. The available working memory is
a crucial parameter for the pre-play recording schedule.
Depending on the model, embedded recorders have
between 512 MB
–2 GB of working memory to manage
all the background processes of all cameras. In order to
create pre-play recordings, the information for each
individual camera, depending on the resolution,
bitstream settings and pre-play schedule, must be
permanently kept in the memory. A pre-alarm memory
of a few seconds is already hard to achieve with the use
of 1080p cameras. The higher the resolution of the
cameras and the more cameras connected to the
recorder, the lower the chance of having enough
memory ready for all cameras. Due to the variety of
models and configuration settings, as well as the
complexity of the evaluation of current scenes, we
cannot provide a reliable value for the pre-alarm
memory. As a result, we recommend using continuous
recording for critical cameras and then using the Smart
Search to easily filter out events.
Video Signal Loss
Please note that as your recorder searches
continuously for video signals, the following applies to
every channel.
If no camera is connected, the following display will
appear on the monitor:
This display does not mean there is a technical defect
or fault on your recorder unless there is a camera
connected to the channel.
It also causes a "video signal loss" error, which is
displayed in the "Alarm/exception information" window.
You will find this under the symbol below:
You can deactivate the display of "video signal loss"
errors manually under "Alarm/exception information->
Adjust -> Video signal loss checkbox".
Warning
Bear this information in mind when
problems/limitations occur in the local live
image view, and troubleshooting is required,
when the device is operating.
