I don't know that router, itself, but it's probably 12V at 1.5 to 2 amps.
Just check the wall wart (adapter). It will list the output right on it.
Also make note of the plug's polarity. Usually, center is positive (there are rare exceptions where center is neg.)
Then, you can go to Radio Shack or some electronics store and see if you can get a 12V to 12V REGULATED adapter. It's the regulation that's important, because a battery can charge up to 15V easily. This COULD cause a problem with the router, unless it has good built-in regulation on power input.
Whatever you do, put an in-line fuse rated same as orig. adapter. DO NOT GO HIGHER. Doing so could blow up the router.
For the cam, I'm not near my cam right now, so I'm not 100% if it's 12V or 5V. I THINK it's 5V. Again, check its adapter. It will list it there as well as the amps.
Let's say it's 5V. Again, you can get, from Radio Shack or an electronics store, a car multi adapter. It's one that plugs into your cigarette lighter and you can switch voltages. Usually, 1.5V, 3V, 4.5V, 9V, 12V.
By the way, if you do see a multi that has 12V AND it has amps at least equal to the router's adapter's amps, you could buy 2 of these. One for the router and the other for the cam.
To make life easier, you could even buy 2 cigarette lighter sockets to use to connect this all up with. This would give you quick connect/disconnect. Just a thought.
Again, put a fuse in-line with the adapter to the camera; keep the amp rating equal to the adapter for the cam.
I might even go 1 step more and put another fuse, coming right off the battery to the Positive lead that powers BOTH adapters, equalling the total amps of both the other fuses, added together.
As for the plugs, just bring the 2 adapters with you when you go to get materials and have the person at the store match up to the same type.
Happy soldering!
