Basically, you will need a PC or a router with enough intelligence (OS) to run the aircard and provide power.

The chip set in the aircard is smart enough to see the network and recognize it, but will only connect when something/someone tells it to. That's where the PC client from Vz comes in. You need that or something similar to control aircard. Companies like Digi and Airlink (now part of Sierra Wireless) make routers like that, but they already have a wireless modem embedded. Look at Linksys and Junxion to see if they have anything that might work.

Now, that may settle the problem of getting on the air, but there are two other issues you'll have to face:

1) What is the camera going to do and where is it sending its video feed? That's really what you are going to need a smarter device to control.

2) Be prepared for a horrendous phone bill from Vz. You may even get an invitation from them to stop sending over their network!

What will will do is via a FTP server is send x number of frames per/min. With the understanding that megapixel cameras (i.e. 3.1 is compressed to about 225k), this problem with a disastrous phone bill no longer becomes such an issue, only simply mathematics.

I don't believe that you will be able to directly interface the router to the air card, what you might have to do is use a computer for the air card and run the ip camera to a switch or the LAN port on the computer. One problem is that the air cards log off after a certain interval of time, and you need to restart them. Where is the camera being installed? do you have another means of viewing it over a network?
