display. Reduce the number of display items, or select a layout with fewer monitor windows. You can also try shortening the camera name.

•During playback, a large value appears momentarily for the bandwidth and number of frames received. Refer to the number of frames displayed to confirm playback performance.

•The number of incoming frames is not displayed for layouts with 17 or more camera images. The number of frames recorded is maintained, but the number of frames displayed is limited. Confirm the number of incoming frames with a layout of 16 or fewer cameras.

•When the NSR is experiencing a high processing load, video images may freeze momentarily, and response time for button functions such as camera control operations (PTZ) may become slow. There may also be a delay in the image display of the NSR unit when compared to the image display of a remote client.

•When you select Border for the mask type, be aware that part of the mask may be cut off depending on the size of the monitor window. If this occurs, increase the width of the mask to make sure it displays correctly.

Camera Control

•After you register a camera, the AUTO buttons under Camera Control light up when focus/brightness adjustment is available. If the actual focus/brightness settings are not that of the auto settings, click the [–] or [+] button and then click the AUTO button to adjust to the auto settings.

•When you perform camera control operations (PTZ) while dynamic masking is active, the processing speed for mask tracking may decrease, exposing the masked area. Be sure to cover a sufficient area when configuring the masking settings.

•Direct pan and tilt, area zoom, and zoom operations with the mouse wheel can only be performed while pressing the Ctrl key on the left side of the keyboard. The Ctrl key on the right side of the keyboard does not work for these operations.

Recording, Playback, and Searches

•When you activate alarm recording in a recording schedule, any alarms that occur during an alarm recording will be ignored until the first alarm recording process completes.

•When you stop recording for multiple cameras simultaneously, some of the recordings may fail to stop if the NSR is experiencing a high processing load. If recording does not stop, perform the stop operation again.

•Searches for recorded images (quick search, PLAYBACK button, search screen) may time out when the NSR experiences a high processing load. If this happens, switch to the live image, and perform the search for recorded images again. If the search still times out, lower the processing load of the NSR, such as by reducing the number of monitor windows displayed, and then perform the search for recorded images again.

•Up to 5,000 results matching the specified search criteria are displayed in the Search screen. If there are more than 5,000 recorded images matching the criteria, narrow the criteria, and perform the search again. Be aware that the number of search results is not displayed.

•Image updating stops temporarily when searches (quick search, PLAYBACK button, Search screen, Export screen) are in progress. Updates resume once a search is complete.

•If you enable cleanup for a storage location, a system alert will not be generated when the remaining capacity for that location is lower than the value set for the alert function.

•The maximum duration for a pre-alarm of a schedule can be as long as the buffer for recorded images (approximately 5 MB) allows. The maximum duration available for pre-alarm recording can be determined from the recorded image size and frame rate.
