This company sells primarily video security equipment. But they have cameras
down to 1" cube, so you're sure to be able to find the perfect camera for your
installation. 

As far as splitters are concerned, they usually produce 4 images (quad split),
9 images, or 16 images. While it's possible to do a 2-way split, you'd lose
half of each camera's image. With a quad split, you'll see all of each
camera's image, but each image will be 1/4 size. Remember, whatever splitter
you use is another piece of electronic equipment you'll have to carry. So
there's still no free lunch.

My best suggestion for two cameras is a simple A/B switch. This is also the
cheapest option. The switched output can be fed to a VCR as well as to the
monitor, so provides a convenient way to select what camera you are recording. 

Another option is two separate monitors. Same equipment count as the A/B
option, but takes more panel space.
