best external security camera image
DPUCCIO
I am trying to use port forwarding to view security cameras over the internet. My camera system, using DHCP, has an IP address of 192.168.0.100. The data is set to come out of port 1026. The camera system is plugged into a hub with an IP address of 192.168.0.1 (set statically). That hub is, in turn, plugged into a DSL modem (which can also work as a Wireless Hub/DHCP server) with the internal address of 192.168.0.2 and an external address of 71.38.68.47. Internally, I can see all devices on the network whether I am plugged into the hub or have linked to the wireless modem. I have set port forwarding on the DSL modem to forward 192.168.0.100 port 1026 for both TCP and UDP protocols. It seems like I have done everything right. I have set-up a similar arrangement in the past with success. But currently, I cannot call the WAN IP address of the modem : port number of the cameras and get the picture. Maybe it is in how the modem and wired hup are linked. Appreciate any help.

On the *nix box in question type:
netstat -anp | grep LISTEN
and it'll show you all the open ports.
From another box use the nmap program (find on Yahoo! search) to scan for open ports on your boxes.

Home security camera surveillance-how much does a basic set up cost?

Lost of crime in my neighbor and interested in home camera surveillance. Is it expensive and is it worth it?
Answer
You can purchase a variety of different systems, ranging from a few hundred dollars to a few thousand. You probably don't need the most expensive systems (unless your house is huge). A good option would be to place external security cameras in areas that a thief would most likely pass through before he entered your home. You can then attach the security cameras to a DVR so that they only record when there is activity.
However, I think its important to point out that while security cameras are great, they are only one (optional) component of home security. Your first goal should be a home security system. You can purchase these online and install them yourself. They are the same models as you would receive from ADT or Brinks, but at a fraction of the cost, since you do the actual installation (which is not that difficult). The site below is a good resource for home security systems and camera systems. Good luck.
