Troubleshooting

	The maximum frames per second is dependent on the utility frequency (60/50 Hz) of the Axis
	product. See Technical Specifications, on page 53.
Video and image problems, general

Image unsatisfactory	Check the video stream and camera settings under Setup > Video & Audio > Video Stream and
	Setup > Video & Audio > Camera Settings.
Motion Detection triggers unexpectedly

Changes in luminance	Motion detection is based on changes in luminance in the image. This means that if there are
	sudden changes in the lighting, motion detection may trigger mistakenly. Lower the sensitivity
	setting to avoid problems with luminance.
No audio

Incorrect setup	Check the sound card in the computer. Ensure that mute is not selected and that the volume
	settings are correct.
	Check that Enable audio support is selected under Setup > System Options > Security > Audio
	Support.
	Check that the correct Audio Input source is selected under Setup > Video & Audio > Audio
	Settings.
Poor audio quality

Stuttering	Reduce the number of listeners and viewers. Decrease image resolution and compression.
Unsynchronized audio and	Synchronize the product’s date and time settings with an NTP server. Go to Setup > System
video using H.264	Options > Date & Time.
Distorted audio	Check that the correct Audio Input source is selected under Setup > Video & Audio > Audio
	Settings.
Feedback loops	Feedback loops might appear in full-duplex mode. Try moving the microphone or the speaker, or
	use half-duplex mode instead.
Storage and disk management problems

Storage disruption	A storage disruption alarm is sent if a storage device is unavailable, removed, full, locked or if other
	read or write problems occur. To identify the source of the problem, check the System Log under
	System Options > Support > Logs & Reports. Depending on the problem, it might be necessary to
	re-mount the storage device.
	For information on how to set up a storage disruption alarm, see Events, on page 29.
Video cannot be recorded	Check that the SD card is not write protected (that is, read only).
