In “TCP/IP Setup” web page, you can assign a static IP address for your camera, even you can alter the HTTP Port or RTSP Port for your camera. In most cases, this TCP/IP setup web page is useful for the people who needs:
- Assign a static IP address for camera to avoid IP conflict.
- Alter the HTTP port or RTSP port from 80 to other value if there is another device or software requires 80 port.
- Assign a constant IP address for camera in order to remotely access the camera web application when the router doesn’t support UPnP feature.
What is IP address?
On your home network (LAN) all your computers, printers and other network connected devices have an IP address. In every IP address there are 4 groups of digits that can each vary from 1 to 255. For your home network the first 3 numbers are already determined by your router’s address, which is typically something like 192.168.0.1 or 192.168.1.1 or 10.0.1
To pick a permanent address for your camera you first need to know your router’s IP address. It is shown in your camera’s “System” menu (at the top of the setting screen) if you scroll down to “Default Gateway“. The router’s IP address determines the first 3 groups of digits for your camera’s IP address.
Now we need to select a valid number for the last group of digits. We don’t simply pick a random number because we have to avoid numbers that are already taken or could be used by your router. The router uses addresses in a range set aside for this purpose (called the DHCP range). For many routers, this DHCP range is from 2 to 100 but you’ll have to check your specific router’s DHCP menu. Sometimes this is shown as start and end address, or start address plus number of available addresses.
Why is this important? We want to select an address outside this range to make sure that your router would never pick this address for another device.
For example, if your router uses the DHCP range from 192.168.1.2 to 100, You could choose 192.168.1.101 as a permanent IP address. Conversely, if your router uses DHCP addresses from 100 to 255, you could use 192.168.1.50 to be outside the range. Never use addresses that end in .0 or .1, since that is reserved for your router, and never use addresses that end in a number higher than 255 since that is the highest possible limit.
See TCP/IP setup web page
The Titathink camera is setup to obtain an IP address automatically (DHCP) from your Network by default, so these settings should not be needed by most users. If your network supports a DHCP server (e.g. router) select this option to have the IP address is assigned automatically. If you select Obtain an IP address automatically and you should select Obtain a DNS Server address automatically.
When you have a need to assign a constant IP address for camera, you should select “Use the following IP address“.
See the mean of each parameters:
- [Use the following IP address] Select this option when a fixed IP is required.
- [IP address] Type the IP address of your camera (Required).
- [Subnet mask] Type the subnet mask (Required).
- [Default gateway] Type the default gateway (Required).
- [Primary DNS IP address] Type the IP address of the primary DNS server, if necessary (Optional).
- [Secondary DNS IP address] Type the IP address of the secondary DNS server, if necessary (Optional).
- [HTTP port number] The default HTTP port number is 80.
- [RTSP port range] In order to view video over RTSP, the router should be setup to forward a port in the range 30000 to 30100 to the camera’s IP address using UDP with an internal port in the range of 30000 to 30100.
Thee procedure of assigning an IP address manually
- Click on “use the following IP address”. Then enter the IP address you picked that is outside your router’s DHCP range.
- Do not change the subnet mask. The default setting of 255.255.255.0 is correct unless you have a very unusual home network.
- Then enter your own router’s address in the “Default Gateway” box. Note that the first 3 groups of digits should be the same as your camera’s IP address. Usually the last digit is 1, sometimes it is 254.
Note: It is very important to add the “Default Gateway” when assigning static local IP. While the camera gets this information automatically from the router when using DHCP, the camera will not obtain this information if a local IP address is assigned manually.
- Then click on “Use the following DNS server” and Leave DNS server settings blank or enter both the primary and secondary DNS addresses that you obtained from your router menu or from your computer’s network connection menu.
- HTTP/RTSP PORT: Leave it the default setting. The HTTP port is usually 80.
- RTP port range: Leave it the default setting or enter the RTP port as below: The RTP port range should start at 30000 for your first camera. For all additional cameras the start of the range increase by 2, for example your 2nd camera would have a starting RTP port of 30002, the 3rd camera would have 30004, 4th camera at 30006 etc.
- After you click on “Apply”, you need to log in to the camera at the address you just picked. Remember to add the http:// in front of the IP address, as in http://192.168.168.120. If your port is not 80 you need to add the port too.
From now on, regardless of what computers or other devices you have on your own network and regardless of the order that you turn them on or off, you camera’s IP address will always be the same.
On some routers, for example some older models of Leviton or NetGear, you may also need to tell your router about the network camera’s IP address, so that it shows up as a known device on your network.
