AXIS V5938 PTZ Network Camera
The web interface
Trigger delay: Enter the minimum time that the tampering conditions must be active before the alarm triggers. This can help
prevent false alarms for known conditions that affect the image.
Trigger on dark images: It is very difficult to generate alarms when the camera lens is sprayed, since it is impossible to distinguish
that event from other situations where the image turns dark in a similar way, for example, when the lighting conditions change.
Turn on this parameter to generate alarms for all cases where the image turns dark. When it's turned off, the device doesn't
generate any alarm when the image turns dark.
Note
For detection of tampering attempts in static and non-crowded scenes.
Audio detection
These settings are available for each audio input.
Sound level: Adjust the sound level to a value from 0–100, where 0 is the most sensitive and 100 the least sensitive. Use the
activity indicator as a guide when you set the sound level. When you create events, you can use the sound level as a condition.
You can choose to trigger an action if the sound level rises above, falls below or passes the set value.
PIR sensor
The PIR sensor measures IR light radiating from objects in its field of view.
Sensitivity level: Adjust the level to a value from 0–100, where 0 is the least sensitive and 100 is the most sensitive.
Shock detection
Shock detector: Turn on to generate an alarm if the device is hit by an object or if it is tampered with.
Sensitivity level: Move the slider to adjust the sensitivity level at which the device should generate an alarm. A low value
means that the device only generates an alarm if the hit is powerful. A high value means that the device generates an alarm
even with mild tampering.
Video input
Each video input is terminated using a coax/BNC connector and displayed as a numbered channel.
Connect a 75 Ohm coaxial video cable; the recommended maximum length is 250 m (800 ft).
Automatic: The default setting. The encoder detects the video standard and resolution automatically.
Manual: Lock the channel to the selected video standard and resolution.
Reload: Click to restore to the current encoder settings.
Mark as configured: Click to acknowledge the video input settings. The video input is shown as configured in the Status page.
Save changes & restart: Click to save the changes and restart the device. If you restart the device, it will affect ongoing recordings.
