Is Web Cam port 8081 forwarding a security risk?

Specs: Windows 8, I5 / 15Gb
I have one web camera that I use for remote monitoring my home. It is configured to forward out port 8081 and my router is configured to do that. I can view it remotely just fine, and I use an Android AP on my phone to few the camera with my Android phone.

My ISP uses dynamic IP and changes my IP address occasionally. I am using DDNS and access my camera using a host name, and I use their DNS servers. My router supports this particular DDNS service and seems to be working just fine. The Android AP uses naming and works just fine as well.

I get the typical port scans from China as just about everybody does. They focus on port 8081. My camera has a password, but it is only 7 characters.

The other internal LAN PCs are all protected with Antivirus and Malware programs. I have UPnP disabled on my router. The camera is on 24/7, but my other PCs only as required.

Since I have port 8081 forwarded, that “opens” the port to the Internet for anyone to try on that port. My only protection is the DDNS naming and 7 character password on the Web camera.

Given that I have port 8081 forwarded, am using DDNS, and the camera password is only 7 characters, is it possible for a persistent outsider to gain access to my camera?

Should they be successful, can an exploit be used to access my other internal LAN PCs?

The port scans don't focus on that port because of your camera. Your camera isn't the only thing that uses that port.

There should be a way to move the camera to another port. Read their docs or contact their tech support.

Oh I can move it to any of the 65K port numbers. I'm just trying to limit the port scans and if my web cam was being detected. All the port scans reported by my router are on 8081. I wish there was a way to block all port scans, but that will restrict my ability to use the Web Cam remotely.

You can't block all port scans but there is a program that will tell whomever is doing the scan, that all ports are opened. That makes the port scan worthless. I don't know if that program is available, for windows. Check the documentation, of the camera or contact them to see if you can change the listening port #.
