Mega-Pixel security system. should i get BNC or POE ?

[Ron Ron]

I currently have analog BNC set up. I want to get a new system with Mega-Pixel cameras.

I was able to find analog BNC 8 ch 4MP camera system for $450 w/ 8 cameras (Costco Wholesale).

I found a POE system 8 ch 4MP camera system $600 w/6 cameras. Audio in all.
(Swann 8 Channel 1080p HD IP NVR Security System with 4 3MP Cameras, 2TB Hard Drive, and 100' Night Vision - Sam's Club)

I am not sure which one is better to get? Audio in all cameras would be good but for the price I dont know if its worth it. Will I see a difference in these two? When I zoom will I get same clarity on both? or what about sharpness of the face or license number?

Please help

Depends on the cabling you've already got installed. If none, definitely go with an IP solution.
As always, you get what you pay for, and Costco / Swann are notoriously poor quality.
