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.

• 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.

• 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.
