VCA settings
The configuration of each individual VCA (Video Content Analysis) event is done in the
camera browser. Within the encoder, you are able to link actions to a VCA alarm from
IP cameras that support this feature.
The encoder can be set up to detect several types of VCA events, which can then
trigger a series of linkage methods:
• Audio Input Exception
• Cross Line Detection
• Intrusion Detection
• Sudden Scene Change
Audio input exception
Audio exception detection detects sounds that are above a selected threshold.
You can set it to detect a sudden rise and/or fall in sound intensity. The smaller the
sensitivity level set, the larger the change in sound needs to be to trigger detection. The
sound intensity threshold filters the sound in the environment. The louder the
environmental sound, the higher the value.
To setup audio input exception actions:
1. From the menu toolbar, click Configuration and then Remote Configuration >
VCA > Audio Input Exceptions. The Audio Input Exceptions window appears.
2. Select a camera from the drop-down list.
3. Select the type of audio input exception.
Click the Exception Detection tab. Select the type of audio input exception to be
detected: Audio Loss Detection, Sudden Increase of Sound Intensity, or Sudden
Decrease of Sound Intensity.
