I don't think this unit in comparable to the hdcctv style products at all.
Almost every camera has some cable between the image sensor and the processing/encoding board. For most cameras, this cable is very short because the desire is to keep all the parts inside of a single small enclosure that can be sealed from dust, elements, etc.
For this camera, Axis targets a small niche, customers who want to mount camera sensors in unique enclosures or areas. This could be for covert purposes, for aesthtic purposes, or other reasons. But for those cases the desire is to have an image sensor in the smallest possible form factor.
Hdcctc products generally exist to reuse coax cables (though there are options for twisted pair), and they all try to emphasize the max cable length they can support. They also usually connect back to a DVR, which handles encoding, viewing, storage and so forth. The Axis camera base really would need a VMS in most cases (yes, I'm sure it has a simple web interface and maybe an SD card slot, but it wouldn't be a "full" system for most uses).
