DDNS - Dynamic Domain Name Service. Use dyndns.org to track your IP on the Internet and
assign it an easy to remember domain name instead of an IP number.
Dynamic IP (DHCP) - A DHCP server assigns an IP address automatically when a device
connects to the network. A dynamic IP can change when a device is restarted.
Firmware - The built-in software that controls the DVR’s functions. Higher firmware version
may be released to provide additional features. Please check this product at www.svat.com to
ensure you have the latest firmware version installed. Go to Menu > System Setup to view the
firmware version running on your DVR.
Frame Rate - The number of frames that are recorded per second. Setting recording to 30
frames/second will provide smooth playback but will increase the file size. Setting recording to
lower frame rates will make playback less smooth, but will decrease the file size and you will be
able to record more video on your DVR’s hard drive.
IP (Internet Protocol) - A network and transport protocol used for exchanging data over the
Internet. The address is a string of four numbers separated by periods (such as 111.22.3.444)
used to represent a computer or other device on the Internet.
Monitoring Mode - The default mode when the DVR starts up. It will display a quad view of
your cameras.

You cannot enter recording mode or access the menu system directly from this mode.
Record Mode - The DVR enters this mode after you press record, or when there is a scheduled
time or motion recording. You cannot enter playback mode or enter the menu system directly
from this mode.
