As you know FG (since you reportedly have a SecureView), the lens has somewhat of a fisheye effect. That increases the viewing area, but reduces much of the detail at distances. I don't know how many parking lot cameras using any technology provide the detail necessary to identify someone by face. The SecureView unit can certainly do so if they're relatively close, but that's about it. Most parking lot systems I have seen appear more interested in vehicle traffic or suspicious pedestrians or activity. The viewer sees something unusual, then moves to investigate it. I don't think the intent is to be able to compare someones picture with a police lineup.
Also, I don't know if SEVU plans to use the exact configuration I have for parking lots, or if they'll use something different. It would seem that the value is in the ability to transmit the image via existing electrical wiring, so I'd assume they could attach any type of lens they wanted.
