URGENT: IP vs HD over analog for New Gas Station build

Hi - I'm trying to figure out what cameras to install for a new gas station we are building. I'm not a CCTV expert which is why I'm here. Basically I need to know if I should be using IP cameras or HD over analog (and hence run cat5 or coax cables). I need cameras inside the retail store (not big - 1200sqft) and cameras outside (include covering 4 fuel pumps).

I need to make a decision regarding coax or cat5 ASAP so any advise is appreciated.

Also - anyone have experience with optiview cameras? http://optiviewusa.com/

My current CCTV guy is recommending using HDover coax cameras from optiview (and run coax cables). I was doing a little research to make sure this is the best option.

thanks

Run Cat6 better than Cat5. Forget about coax, if you want to use HD over coaxial cable, at least use UTP cable witb baluns.

I would go with cat 6 also and look into if by code in your area you need outdoor rated and or plenum rated cable. I know that there are specific requirements for fire blocking conduit from pump islands to main building.
