I would also like to see the color/BW version, although I'm not sure I'd pay substantially more for it. I think the existing BW version does as much as I'd ever need. The zoom capability could be enough to justify a moderate price increase, though.
As for the lens, I didn't mean the camera optics. I assume you're referring to my comment about marking the top of the system. My thought is that if the assembler can identify the orientation of the optics before attaching the semi-transparent screwtop (which I referred to as a lens), they could simply mark the orientation on the outside of the housing. It's really no big deal. It just seems like an easy improvement, regardless of how minor or unnecessary it may be.
I don't share your concern about the parking lot system, although I may be making an erroneous assumption. I haven't given it much thought, but I would think a parking lot system would be designed much differently than the retail SecureView I have. I'm not a techie, but I'm assuming that just about any type of existing parking lot camera configuration could be emulated. We know that cameras exist for this purpose today. The value added by using a SEVU system would be the use of existing wiring, rather than having to hard wire a new system. That's a more appropriate issue for Adam to address. I honestly don't have a clue.
