Description

Object size r ela tive to window

size.

Object memory length.

Difference in luminance

between background and

object.

High level (100%)

Only very large objects trigger

motion detection.

An object that appears in

the window triggers motion

detection for a long time

before it is co nsidered as

non-moving.

Ordinary colored objects on

ordinary backgrounds trigger

motion detection.

Medium level (50%)

A large difference in luminance

is required to trigge r motion

detection.

Low level (0%)

Even very small objects trigger

motion detection.

An object that appears in

the window triggers motion

detection only for a very short

time before it is considered as

non-moving.

Only very bright objects on

a dark background trigger

motion detection.

Recommended values

5–15% 60–90% 75–95%

Default values

15% 90% 90%

Tips:

• To trigger on small objects or m ovements, use several small motion detection windows rather than one large w indow

and select a low object size.

• To avoid triggering on small objects, select a high object size.

• If no objects should appear in the Include Window, select a high history level. This will cause motion detection to trigger as

long as the object is present in the window.

• To only detect ﬂashing light, select a low sensitivity. In other cases high sensitivity is recommended.

Audio d etection

The Axis p roduct can be conﬁgured to generate an alarm when audio rises above or falls below the threshold value. The threshold

value can be set in the range 0–100 where 0 is the most sensitive and 100 the least sensitive.

1. Go to Detectors > Audio Detection.

2. Set the audio alarm level and click Save.

3. Go to Events > Action Rules and set up an action rule, see Setting Up an Action Rule, on page 27.

Note

dio alarm is disabled by default during PTZ movement. To enable, clear the Alarm automatically disabled during PTZ

movement check box option.

Detected audio is indicated by colored peaks in the Activity indicator. An e v ent is triggered when detected audio rises above or falls

below the threshold value, w hich is represented by the bar.
