Record on

Select under which conditions video from the camera should be

recorded:

 Always: Record whenever the camera is enabled (see

"General" on page 86) and scheduled to be online (see

"Online period" on page 134) (the latter allows for time-

based recording).

 Never: Never record. Live video will be displayed, but—

since no video is kept in the database—users will not be

able to play back video from the camera.

 Motion Detection: Select this to record video in which

motion (see "Motion detection & exclude regions" on page

96) is detected. Unless post-recording (see the following) is

used, recording will stop immediately after the last motion is

detected.

 Event: Select this to record video when an event occurs

and until another event occurs. Use of recording on event

requires that events have been defined, and that you select

start and stop events.

Use the Configure events list, located below the other

fields to define events that suit your needs.

 Motion Detection and Event: Select this to record video in

which motion is detected, or when an event occurs and until

another event occurs. Remember to select start and stop

events in the neighboring columns.

Start Event

Select required start event. Recording will begin when the start

event occurs (or earlier if using pre-recording; see the following).

Stop Event

Select required stop event. Recording will end when the stop event

occurs (or later if using post-recording; see the following).

Pre-recording

You can store recordings from periods preceding detected motion

and/or start events. Select check box to enable this feature. Specify

the required number of seconds in the neighboring column.

Seconds [of pre-recording]

Specify the number of seconds for which you want to record video

from before recording start conditions (that is motion or start event)

are met. Usually, only some seconds of pre-recording is required,

but you can specify up to 65535 seconds of pre-recording,

corresponding to 18 hours, 12 minutes and 15 seconds. However, if

specifying a very long pre-recording time, you can potentially run

into a scenario where your pre-recording time spans scheduled or

unscheduled archiving (see "About archiving" on page 126) times.

That can be problematic since pre-recording does not work well

during archiving.
