Important • Using preset tour with MPEG-4 or H.264 format will consume a large amount of disk space. • The preset tour settings can effect the durability of the camera's pan/tilt mechanism. Note The camera returns to the first preset position after reaching the last preset position. Hint Click [Start Test] to run through the preset tour once to confirm your settings. About the Warning Message Displayed During the Preset Tour Depending on the preset tour settings, a warning message about the camera's pan/tilt mechanism may be displayed when you click [OK] to close the [Preset Tour Settings] dialog box. If this happens, consider changing the settings according to the following guidelines. A warning will appear when the pan/tilt mechanisms reach their estimated lifetime of 100,000 round trips over the full range of motion. „ Specify the Option for Recording Before and/or After an Event You can record a number of seconds before and/or after an event, such as sensor input or intelligent function, using the [Recording Options] setting. (1) (2) (1) [sec. before event] Number of seconds to record before an event (max. 30 seconds). (2) [sec. after event] Number of seconds to record after an event (max. 999 seconds). Note • [Recording Options] cannot be specified when setting continuous recording. • Even if [sec. before event] and [sec. after event] are both set to 0, recording will continue when events are continuously generated. • The higher the value for [sec. before event], the greater the memory usage for the Storage Server. If the Storage Server has insufficient memory, the server will run out of virtual memory, which consumes hard disk space, significantly reducing processing performance. • If you specify a preset camera angle for sensor recording, the camera angle will change to the preset angle when sensor recording starts. Therefore, the camera angle of the recording before the sensor recording event will be different from the one after the event. If [Recording Options] is set to record a short time after an event and the sensor input is very short, recording may stop before the camera reaches the preset camera angle. 90

About the Warning Message Displayed During the
Preset Tour
Depending on the preset tour settings, a warning
message about the camera’s pan/tilt mechanism may be
displayed when you click [OK] to close the [Preset Tour
Settings] dialog box. If this happens, consider changing
the settings according to the following guidelines.
A warning will appear when the pan/tilt mechanisms reach
their estimated lifetime of 100,000 round trips over the full
range of motion.
Specify the Option for Recording Before and/or
After an Event
You can record a number of seconds before and/or after
an event, such as sensor input or intelligent function,
using the [Recording Options] setting.
(1)
[sec. before event]
Number of seconds to record before an event (max.
30 seconds).
(2)
[sec. after event]
Number of seconds to record after an event (max. 999
seconds).
Note
•
[Recording Options] cannot be specified when setting
continuous recording.
•
Even if [sec. before event] and [sec. after event] are both set to
0, recording will continue when events are continuously
generated.
•
The higher the value for [sec. before event], the greater the
memory usage for the Storage Server. If the Storage Server
has insufficient memory, the server will run out of virtual
memory, which consumes hard disk space, significantly
reducing processing performance.
•
If you specify a preset camera angle for sensor recording, the
camera angle will change to the preset angle when sensor
recording starts. Therefore, the camera angle of the recording
before the sensor recording event will be different from the one
after the event. If [Recording Options] is set to record a short
time after an event and the sensor input is very short, recording
may stop before the camera reaches the preset camera angle.
