Access Engine Log

A list of messages shown in the Storage Server log file nvr_ae_log_<N>.txt (<N> is either 0 or 1) is shown
below. These messages are generated by the access engine (Win32 service) that runs as part of a Storage
Server.
Messages

startup complete.
Log level = <log
level>

has finished shutting
down.
Cause
The recording frame rate has been
changed from y% to z% because the
load of the recording engine continued
to increase (decrease).
An HTTP 400 error occurred when
getting the image.
Recording video stream requests were
made to the VB-C500VD/VB-C500D/
VB-C60 from multiple Storage Servers.
Cause
It indicates that startup of the access
engine has been completed.
The access engine has been stopped.
Action
Even though there is no necessary
action, you can reduce the system load
using the following methods if you want
to avoid frame rate decrease events.
1. Reduce the amount of data to record
(For example, lower the resolution or
frame rate).
2. Install an additional hard disk.
3. Implement an action such as
upgrading the CPU, or increasing
memory or existing hard disk space.
It may be connected to SNC-P5, DF40N
in the MPEG mode. Change it to the
JPEG mode. For other causes, see the
corresponding HTTP error code in "Error
Codes in Log File" ( P. 9-31).
Change the settings such that the
recording video stream request is only
made by one unit.
Action
No action is required.
