    identifying the SA, be careful not to specify an 
    inbound SPI whose value is already used in the SPI for 
    another AH. 
    Note
    If IPsec is used, video transmission performance drops.
    Important
     To run this camera with IPsec, the communicating devices 
    and network must be set beforehand. Contact your System 
    Administrator for these settings. 
     When connecting with IPsec, set the camera IP address 
    manually.
    For IPv4 addresses, use addresses set with [Network] > 
    [IPv4 Address Setting Method] > [Manual].
    For IPv6 addresses, use addresses set with [Network] > 
    [IPv6 Address (Manual)].
     If any setting is changed from the [IPsec] menu, the camera 
    may become inaccessible from the active web browser. 
    Check beforehand the precautions in “Important” in “[Reboot 
    Item] Setting Items Requiring Rebooting” (p. 72).

    Note
    To install an intermediate certificate and a primary intermediate 
    certificate, use a text editor or similar software to place them in 
    the same file and install them as an intermediate certificate.
    (5) [Delete Certificate] 
    Click [Exec] to delete the certificate. However, if SSL

    When a memory card is inserted in the card slot, it is mounted 
    automatically. It is also mounted automatically if inserted in the 
    camera at the time of booting. 
    For inserting and removing the memory card, see “Installation 
    Guide” > “Using a Memory Card”. 
    (2) [Operation Settings] 
    Set write operations to the memory card to [Save Log] 
    or [Save Logs and Videos].
    Note
     The following settings and operations will record video on a 
    memory card.
    - When a network error occurs during recording-mode stream
    - When uploading fails
    - When [Video Record Action] in the [Event] menu (p. 56) is 
    set to [Record to Memory Card], and an event (volume 
    detection, external device input or timer) setting is enabled 
    and [Enable] is selected for [Video Record]

    occurrence (p. 77)
    - When manually recorded to memory card from the Admin 
    Viewer (p. 140)
     New files cannot be saved to the memory card if there is no free 
    space.
    (3) [Video Format]
    Select the [JPEG] or [H.264(1)] video format to make 
    recordings to a memory card. 
    Video is recorded with 
    the settings defined under [Video] > [H.264(1)] (p. 46). 
    [H.264(2)] cannot be used. Video is recorded in this 
    format when [Record to Memory Card] is selected in 
    [Event] > [Video Record Action] (p. 56).
    Note
     When [JPEG] is selected in [Video Format] and an upload error 
    occurs, the frame rate of video recorded in JPEG format is 
    always 1 fps.
     When a network error occurs during recording-mode stream, 
    video is saved in the JPEG format regardless of the [Video 
    Format] setting (the frame rate is fixed at 1 fps).
     Video size and quality of the recorded video are made 
    according to the settings in the [Video] menu.
    (4) [Pre-event Buffer (number of frames)] / [Pre-event 
    Buffer (sec)]
    Enter the number of frames or seconds of video to be

    Format].
    (5) [Post-event Buffer (number of frames)] / [Post-event 
    Buffer (sec)]
    Enter the number of frames or seconds of video to be 
    buffered after the event. The maximum amount is 
    number of frames for a [JPEG] selection and number 
    of seconds for an [H.264(1)] selection in [Video 
    Format].
    (6) [Overwrite videos]
    Select [Enable] or [Disable] for the overwrite setting of 
    video that is recorded to a memory card when an 
    event occurs. If you select [Enable], videos recorded 
    using an event and timer will be overwritten. 
    Overwriting is performed when the number of 
    recordings that can be stored (100,000 files) for each 
    of events and timers is exceeded. Overwriting is not 
    performed when there is insufficient space on the 
    memory card.
    (7) [Format]

    memory card becoming inaccessible. 
    You can use the Memory Card Unmount Tool (p. 15) to mount/
    unmount memory cards from multiple cameras at the same 
    time.
