What are the recommended system requirements for your products?

Graphic cards are said to have great influence on the DVR Boards. What graphic cards do you recommend?

The first recommendation would be the graphic cards manufactured by ATI(Rage 128pro, Radeon).
Another recommendation would be the GeForce2 MX 200/400, from nVIDIA, but when using this graphic card you will have to use the driver which we supply, and only use in a Windows 2000/XP environment(storage speed decreases when used in Windows 98).

What are the differences of RGB and YUV image signals?

RGB signaling refers to the method of dividing an image signal to the fundamental three colors(Red, Green and Blue) when processing the signal. This image signal has a clearer, crisper looking picture.
YUV signaling refers to the method of expressing an image signal by the vertical and horizontal signal synchronization(Y), and its color signals(U, V). This image signal has a softer picture that is more pleasing to the eye.
On the Sharpvision DVR, both image signals can be carried, allowing the choice to be up to you, depending on which picture you like better.

What are the backup devices supported by the system?

Data backup devices include CD-RWs, DVD-RAMs, DVD-RWs, DATs, etc., any device that Windows recognizes as a drive, and you can also backup on a network drive.
The unit of the data is 1 minute, and can only be viewed through the supplied Backupviewer. Data backup is also possible on the Search program, where it can be saved in AVI format, making it conveniently viewable through the Windows Media Player (by enabling "View-Caption" from the menu, you can also conform information data).

Windows 98 uses the FAT32 file system, while Windows 2000/XP also supports the NTFS file system. Which file system should I use?

Each file system has advantages and disadvantages to them, but we recommend the FAT32 method over the NTFS system. Using the NTFS system as your database can result in small data glitches.

What is the supported picture quality when recording on Sharpvision?

Each model seems to require different IRQ settings, how should I do it?

There are no special IRQ setting requirements for the Sharpvision-CAP2X30, 2x60, 120, 240, because they can share an IRQ with other devices. However, with the Sharpvision-CAP30/60 you must be careful to make sure an IRQ collision does no't occur. We recommend that you disable all devices not being used when installing these products (MIDI ports, USB ports, etc.).

What is the recommended Windows picture quality for Sharpvision software?

Sharpvision DVR, Sharpvision-Net, and Sharpvision-Web were all designed in a 1024x768 environment. Setting the system to a lower quality can result in screens that are cut-off, so be sure to set your screen to 1024x768 before using your software.

What are the precautions when recording sound?

With Windows 98 or 2000, Direct X 8.0 or better must be installed. Windows XP is supplied with Direct X 8.0.
Soundcard configurations and usable microphones differ depending on how many channels you use. Be sure to check your settings.

What can be done about dynamic IP?

Currently in Korea, dynamic IP systems are more popular than fixed IP systems, including many of the ADSL and Cable modem systems, meaning that the IP address will change frequently.
Sharpvision has the function of e-mailing the current IP address whenever the system starts, to the user designated e-mail address. You can use this address to log-on to the Sharpvision DVR system.
