IP address
Obtain Address
Automatically
If selected, the Network Camera will obtain its IP address and related information from a DHCP Server. Only select this option if your LAN has a DHCP Server.
Use the following IP address If selected, you must assign the following data to the Network Camera.
  • IP Address - Enter an unused IP address from the address range used on your LAN.
  • Subnet Mask - Use the same value as PCs on your LAN.
  • Default Gateway - Use the same value as PCs on your LAN.

DNS Server Address
Obtain DNS server address automatically If selected, the Network Camera will obtain the DNS server address automatically.
Use the following DNS server address
  • Primary DNS Address - Use the same value as PCs on your LAN. Normally, your ISP will provide this address.
  • Secondary DNS Address - This is optional. If entered, this DNS will be used if the Primary DNS does not respond.

Secondary Port
HTTP Secondary Ports This sets the port number for HTTP (Web) connections to the Camera, whether for administration or viewing video.
  • If HTTP Secondary Port enabled, you can connect using either port 80 or the user-defined port. You must enter the user-defined port number (between 1024 to 65535) in the field provided.
Note that when using a port number which is not 80, you must specify the port number in the URL. For example, if the Camera's IP address was 192.168.1.100 and the User-defined port was 1024, you would specify the URL for the Camera as follows:
     http://192.168.1.100:1024

RTP/RTSP
RTSP Port The RTSP (Real Time Streaming Protocol), a standard for connected client(s) to control streaming data (MPEG-4) over the World Wide Web.

If desired to change, enter the RTSP Port number (between 1024 to 65535) in the field provided.   The default RTSP Port is 554.

RTP Data Port The RTP (Real-Time Transport Protocol), an Internet protocol used for transmitting a single real-time multimedia data such as audio and video to a select group of connected clients.   The RTSP uses RTP to format packets of multimedia content.

The Network Camera's data Port number has been pre-configured and can be used for multi casting, and does not normally need to be re-configured. If a port number does need to be changed, please contact your network administrator.

If desired to change, enter the data Port number (between 1024 to 65534) in the field provided.

Max RTP Data Packet If desired to change, enter the Max RTP Data Packet Length (between 400 to 1400 bytes) in the field provided.

Multicast RTP/RTSP
Video Address / Audio Address The RTP (Real-Time Transport Protocol), an Internet protocol used for transmitting a single real-time multimedia data such as audio and video to a select group of connected clients.   The RTSP uses RTP to format packets of multimedia content.

The Network Camera's Video and Audio IP Address has been pre-configured and can be used for multicasting, and does not normally need to be re-configured. If an address does need to be changed, please contact your network administrator.

If desired to change, enter the Video Address / Audio Address in the field provided.

Video Port /
Audio Port
The Network Camera's Video and Audio Port number has been pre-configured and can be used for multicasting, and does not normally need to be re-configured. If a port number does need to be changed, please contact your network administrator.

If desired to change, enter the Video Port / Audio Port number (between 1024 to 65534) in the field provided.   The Video Port / Audio Port number you entered must be even values.

Time to Live Enter a reasonable length of time (usually measured in 'hops' - the number of network routers that can be passed before the multimedia data packets arrives at its destination or is dropped.), if the packets fail to be delivered to their destination within.   The Time to Live you entered must be in-between 1 to 255.

UPnP
Enable Discovery If enabled, the Network Camera will broadcast its availability through UPnP. UPnP compatible systems such as Windows XP will then be able to detect the presence of the Network Camera.
Enable Traversal If enabled,  HTTP connections (from your Web Browser or the Viewer and Recorder utility) can use secondary port instead of port 80 (the standard HTTP port) to access the camera.

QoS
Enable QoS Mode If enabled,  the throughput level (for Video and Audio) is guaranteed through QoS (Quality of Service).
