AurorAcorD design is that all program information is retained
during power outages, and when the power outage ends,
AurorAcorD resets itself and reloads all the user settings. Thus
an AurorAcorD-based system is up and running as soon as
power is restored and does not require an operator to restart it.
Vicon strongly recommends the use of line conditioners, voltage
regulators and uninterruptible power supply (UPS) systems in
the electrical power service.
Passcodes
AurorAcorD incorporates optional passcoding that restricts
access to the programming screens. The passcode can be set so
that it is required to permit modifying the program parameters.
The passcode can also be set to limit the ability to change from
one display format to another. Furthermore, using the password
activation, any video can be locked out from the live display
while still being encoded and recorded. This feature gives an
administrator the ability to collect video while maintaining the
privacy of areas monitored by locked cameras.
In addition, the loss of passcoding can be easily retrieved by a
call to Vicon. This clever method requires a simple call to Vicon
Tech Support to forward an internal encrypted code in exchange
for the lost passcode.
Recording Duration
Recording duration is a very important aspect of any digital
recorder. AurorAcorD uses a wavelet compression algorithms to
condense video information, thus extending the amount of
video that can be recorded.
In addition, AurorAcorD utilizes a “motion-compensation” algo-
rithm that extends the recording even further by comparing refer-
ence scenes to new ones. The following charts are for reference.
Recording durations vary greatly depending on the level of activi-
ty in each scene.
Factors that can affect record duration are motion and contrast
in the scene. The following are examples of these factors that can
limit normal hard drive storage capacity and record duration:
1. A motion-intense camera scene such as a busy street corner,
a
hotel lobby, a highway, an ocean view, etc.
2. A constantly moving item in a camera scene such as a fan, a
monitor, a fish tank, a blinking light, etc.
3. A dark camera scene with the camera’s AGC adjustment set
too high causing excessive display noise.
4. A camera scene with a large amount of contrasting colors and
shades such as a bouquet of flowers.
