How To Reset A TV-IP-551W Camera and Access / Configure It Manually

After being reset to factory defaults, the default IP address for the Trendnet TV-IP551W is:
192.168.10.30 and the default login is: Username: admin       Password: admin
The live video URL for the TV-IP551W is:
http://<camera.IP.address>/video.cgi
See the "HTTP Port..." section below on how to use a modified URL to view the camera from anywhere on the Internet.

To reset the TV-IP551W to factory defaults, insert a paper clip or similar object into the hole on the side of the camera above the WPS button and depress the reset button and keep it depressed for about 5 seconds until the WPS button lights up. You can then remove the paper clip and let the camera boot up (takes about 15 seconds).
You can download a PDF of the user manual directly from Trendnet's Web site here:

You can download latest firmware for the TV-IP551W directly from Trendnet's Web site here:

(SHA-1 Checksum: B857691E0584B64ABE66F2B66DCB8DBF429DD0FE)
ONLY update firmware using the WIRED (not WiFi) LAN connection to the TV-IP551W
To manually set up the TV-IP551W without installing the TRENDnetVIEW software:

1. Connect a network cable between your PC's LAN connection and the wired LAN connection on the TV-IP551W.
2. Boot up your PC and assign a static IP address to it of 192.168.10.4.
3. Plug the power cord into the TV-IP551W and reset it to factory defaults as shown above.
4. On your PC, open a Web browser and browse to: http://192.168.10.30
5. Log into the camera using the above default login credentials.
6. Click on the Administration button above the camera image.
7. Click on the Configuration button on the left side of the page.
8. Click on the System link under Configuration and change the Admin ID and Admin Password. (You can also disable the flashing LEDs in this section if you wish.)
9. Click on the Network link under Configuration and change the camera's network settings to match those of your network.

NOTE that changing the camera's network settings will likely disconnect your from your PC and you'll have to re-establish a connection to the camera to do any further configuration.

The HTTP Port Setting and Internet Viewing

The HTTP Port option in the network settings area offers you the ability to access multiple cameras in your home from anywhere on the Internet. If you have several of these cameras each one will, of course, have a unique IP address, but you could then use the HTTP Port field to assign each of them a unique port number also. This will allow you to set up a separate port forwarding rule for each camera in your Internet gateway router so you could look at the cameras from anywhere on the Internet. Just be sure to use a "non-standard" TCP port number so you don't have problems as some ISPs will block traffic for specific port numbers. The higher the port number the less likely it is to get blocked by an Internet router. TCP port numbers that are already being used are listed here:
https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
HOWEVER, be aware that if you change the HTTP Port value in the TV-IP551W settings to anything other than the default 80, you'll need to include the port number in the URL to access the camera video. For example, if the camera's HTTP Port value is the default 80 you would access the camera video using the URL:
http://192.168.1.100/video.cgi
You would have to change that to start incorporating the non-standard port number in the URL. So if you set the HTTP Port value to 19475 you would have to use the following URL to access the camera video:
http://192.168.1.100:19475/video.cgi
You would then set up a port forwarding rule in your home Internet gateway router to forward port 19475 to IP address 192.168.1.100. That way you could look at that same camera from anywhere on the Internet just by substituting the camera's "inside" IP address (the 192.168.1.100) for whatever public IP address your ISP assigned your modem/router. Or if you are using a Dynamic DNS service to map a domain name to your public IP address, you would use whatever Dynamic DNS domain name you're using, for example:
http://the-smith-ranch.freedns.com:19475/video.cgi
By adding an additional port-number-to-IP-address mapping for each camera on your internal network, you would use this same URL to access all of the cameras from anywhere on the Internet simply by changing the port number.

NOT The Same Port Forwarding Don't confuse the "port forwarding" we're talking about here with the UPnP Port Forwarding option in the Networking settings section of the TV-IP551W configuration. The two are not related in any way. For reasons related to security, you'll be better off disabling BOTH the UPnP and UPnP Port Forwarding options that are just under the HTTP Port option in the Networking settings section.

Associating a device's IP address to a port number is what makes devices (like cameras) on internal, private networks accessible from the public Internet. It provides the basis for the port forwarding that Internet gateway routers do. Using the same functionality, you could set up a Linux system running the Apache Web server software. When the Apache Web server software is running it opens port 80 on the Linux system to listen for requests from browsers. (Web browser applications like Firefox and Chrome request Web pages from servers using port 80.) You would then set up a port forwarding rule in your Internet gateway router to send all incoming traffic for port 80 to the IP address of the Linux system. This is how you can have your own Internet Web server on your home network.
