• If there is no audio, check the audio server settings of the camera and also check the
sound and audio device settings for the PC.
• If you are using the Admin Viewer with the administrator authorities, check if the
camera is connected to the RM Viewer or another viewer that lets the administrator
use audio.
• In VB Viewer, audio cannot be used if the Canon Network Camera Audio Receiver
add-on is not installed.
• When you are using Internet Explorer 10 or 11 in a 64-bit operating system and the
camera is registered as a trusted site and protected mode is enabled, reception and
transmission of audio may be disabled. If this occurs, disable protected mode.
• If you connect the Admin Viewer as an administrator, you will have exclusive
possession of the camera control privileges. If you connect to the Admin Viewer as an
Authorized User, you cannot control the camera unless the administrator releases
camera control. Consult the Administrator (p. 136).
• Check the network and PC for abnormality.
• Reboot the PC and connect again.
• You can initialize all settings of the camera excluding date and time using the reset
switch (p. 180). The administrator password required for initialization is "camera".
Note, however, that network settings such as the IP address and subnet mask will be
initialized and must be set again.
• Check the upload destination in the [Upload] menu, as well as the upload operation
upon event in the [Event] menu, to see if both are set correctly.
• You can perform an operation check based on the currently set upload destination by
running a test (p. 67) from the [Upload] menu.
• Check [Maintenance] > [View Logs] or logs on the server to check the detailed
operating environment. For [View Logs], see "Application (Uploader) Messages"
(p. 169). Also see "Important" in p. 66.
• For the server settings, contact your System Administrator.
• You cannot use recording-mode stream transmission if [Upload] > [Upload] is set to
HTTP or FTP. Set [Upload] to [Upload Disabled] (p. 66).
• To record video to an memory card when an event occurs, check the [Video Record
Action] settings under [Event] in the setting page. When [Video Record Action] is set
to [Upload], change it to [Record to Memory Card].
• When recording-mode stream video that could not be transmitted due to network
errors or video for which the HTTP/FTP upload failed is not stored on the memory card,
check [Operation Settings] under [Memory Card] in the setting page. When
[Operation Settings] is set to [Save Log], change it to [Save Logs and Videos].
• To manually save recordings to an memory card, obtain camera control privileges.
• Windows prohibits saving to certain folders. Accordingly, an attempt to save a file may
fail. Specify [Documents], [Pictures] and other folders.
• Select [Memory Card Information] under [Memory Card] in the setting page to check
[Video Management Information Status]. When [Video Management Information
Recreation Required] is displayed, click [Exec] in [Recreate Video Management
Information] under [Memory Card Operations]. When video management information
has been recreated, make sure that [Video Management Information Status] is
[Normal].
