ok, so this might be a bit of a long one.
i have several pan/tilt IP cameras that i view on my laptop via my LAN. now what i want to know is, how can i use these cameras anywhere i want, even without an internet connection. is it possible? can you crate a LAN without an internet connection? i want to be able to deploy my cameras anywhere i want and still be able to view/control them from my laptop/tablet. ..what i was hoping was that id be able to crate a LAN and connect my cameras to it nomatter where i am. i know it sound like something from Mission Impossible, infact, thats where i got the idea, haha. but there must be some way of doing this....?
thanks for your help:)
Answer
It sounds as though your configuration consists of a wireless capable Internet router, a wireless connected laptop and a number of Ethernet connected IP cameras.
If I have got that right, then disconnecting the router from the connection to the Internet but leaving the other connections in place, should be the basis of the system you are seeking.
Most home wireless routers will provide a local area network including wireless when the Internet connection is disconnected.
If you don't want to use your normal Internet router, you can purchase a router for $20 to $30 that should do the job. Leave its WAN/Internet port unconnected, and configure the other settings with the same IP address and wireless settings as your Internet router and you should be set. If you are testing this at home, turn off the original Internet router to ensure that you are using the correct wireless network.
I hope this helps.

Connecting router with security cameras?
Josh
I just put in a new router at the office and wifi works great but now the 4 Sharx security cameras do not work. They used mulit-view to be over saw when working. anyway how to line the cameras with my router?
Answer
Most security systems have to be configured on the router. I would connect the old router to a PC or laptop via Ethernet and examine it's configuration. Especially, look at the port forwarding and DHCP address reservation sections. Jot down any camera specific settings and transfer the same configurations to the new router.
Here is how it works,
Your security system DVR will have a IP address. It needs to be in the same subnet as your router and you would want to reserve it on your router (DHCP) or set it static on the device so it doesn't change. For example if your router is 192.168.1.1 you could set your DVR to any unused IP from 192.168.1.2 - 192.168.1.254
Your security system will have settings for web port and media port. You really need to look at the manual to see how to set these up. For my Swann system the web port is 85 and the media port is 9000. The web port is used to access your DVR from your local LAN or the Internet using a laptop or PC. The media port is used for mobile phone access.
Both ports must be properly forwarded on your router to the IP of the DVR. For example if your DVR is 192.168.1.2 you would forward the TCP and UDP port 85 to the IP 192.168.1.2.
Then you would access your cameras from your local LAN using the IP followed by a colon and the port number such as http://192.168.1.2:85
To access them from the Internet you will need the WAN address. You use the same process, the WAN IP followed by a colon and the port number.
Let me explain:
A router connects two separate networks and manage the traffic between them.
In most home network applications the router connects your local group of computers and devices known as the LAN with the Internet, commonly called the WAN or Wide Area Network.
The router usually assigns unique Local IP addresses to all of the devices connected to it via a service known as DHCP. The addresses assigned by your router are private addresses http://en.wikipedia.org/wiki/Private_network and are not routable across the Internet.
Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. http://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol
Your cable or DSL modem will get a Public WAN IP address from your ISP. The modem is connected to the WAN port on your router. The router will manage the traffic between the devices on the LAN and the Internet.
You can see your current public WAN IP here: http://www.mywanip.com/
Depending on your ISP your WAN IP might be dynamic (changing periodically) or static (fixed).
If you have a static WAN IP, you will have no problem. However if you have a dynamic WAN IP your IP will change periodically preventing you from accessing your cameras via the Internet.
If the latter is the case then you'll need a DDNS (Dynamic DNS) service. http://en.wikipedia.org/wiki/Dynamic_DNS
Many security camera manufacturers provide free DDNS service. There are also DDNS companies. http://dyn.com/dns/
This will allow you to always be able to access your cameras even when your public IP changes.
Good Luck...
