I'm just getting into the world of surveillance cameras, but I think it's more important to decide what you want to get out of any given camera, than to be concerned with any particular brand of hardware. For example, if you are hoping to capture license plates you will likely want a camera with a narrower field of view so you can get the maximum pixels per inch of coverage area. If instead you want to monitor a large area to just see people coming and going, you might want a very wide field of view, but then don't expect to be able to read license plates or get a really clear face shot from that camera.

Only catch with the Pi might be decode/encode performance if you plan to do anything with the video on that side of things, you'd have to have video software that can take advantage of hardware acceleration on the Pi.
