Advanced configuration

Default Speaker

Select a default speaker.

The ability to select a default microphone or speaker for the camera is only available if at least one

microphone and/or speaker has been attached to a hardware device on the surveillance system.

Recording

The term recording means saving video and, if applicable, audio from a camera in the camera's

database on the surveillance system server. Video/audio is often saved only when there is a reason to

do so, for example as long as motion is detected, when an event occurs and until another event

occurs, or within a certain period of time.

When you configure video and recording (see "About video and recording configuration" on page 64)

for specific cameras, recording properties include:

Name

Description

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.

Conditionally

Record when certain conditions are met. When you select this

option, specify required conditions (see the following) which

enables you to store recordings from periods preceding and

following detected motion and/or specified events.

Example: If you have defined that video should be stored when a

door is opened, being able to see what happened immediately prior

to the door being opened may also be important. Say you have

specified that video should be stored conditionally on event, with a

start event called Door Opened and a stop event called Door

Closed. With three seconds of pre-recording, video is recorded

from three seconds before Door Opened occurs and until Door

Closed occurs.

Built-in motion detection

Select this check box 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.

On event

Select this check box 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

in the neighboring lists.

Use the Configure events list, located below the other fields to

define events that suit your needs.

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).
