4.10.7 Adjusting the picture quality
To adjust the picture quality, use either of two methods as follows:
• Adjust the picture quality of the transferred image on the recorder side.
• Adjust the picture quality of the received image to be displayed on the PC side.
To adjust the picture quality of the transferred image, use the slide bar of [Picture Quality] on the camera window
panel (
see 3.7 on page 12). In DX-TL5000 series recorders, you can specify the picture quality applied in
loading live images and that in playback of recorded images separately. When the picture quality of the transferred
image is decreased, the refresh speed increases even in an environment where the communication band is
insufficient.
To adjust the picture quality of the received image to be displayed, use the slide bar of [Decode Level] on the
camera window panel. There is no problem in decreasing the decode level when the image size is small.
Decreasing the picture quality of the displayed image helps to increase the refresh speed when the PC's
processing capacity is short.
Note
• In DX-TL2500 series recorders, recorded images are transferred at the picture quality level applied when those
images were recorded. You can't change this picture quality level. Even in DX-TL5000 series recorders, you
can't improve the picture quality of the image that was recorded at a low picture quality level.
4.10.8 Adjusting the refresh speed
Regardless of the picture quality, you can adjust the image refresh speed using the refresh speed slide bar on the
camera window panel (
this interval is, the less the restrictions become on the communication band to be used and the load applied to the
recorder.
When the recorder's communication operation is unstable or the network band is insecure, reduce the refresh
speed. When a PC to be used does not have sufficient processing power, reduce the refresh speed.
4.11 Downloading by specifying data section <Section download function>
When you click the Section Download button on the recorder panel (
box appears. Use this dialog box to download recorded images from the recorder by specifying the range of data
by date and time.
Specify the range of data you want to download by date and time and click the [Download] button.
While download is in progress, live viewing and playback of the recorded images of the recorder are automatically
suspended.
In the data downloaded by this function, frame loss may occur depending on the communication condition.
Therefore, the section download isn't recommended for backup use. To download a large amount of data from the
recorder for a long period, it is recommended to use the copy function of the recorder.
