Here's a new argument, courtesy of the HD-CVI Academy:
Gas Station
Different form other applications, the largest challenge for gas station application is the electric spark. For HDCVI surveillance system, all signals are transmitted in coaxial cable, which has thick insulating layer, so users shall never worry about the electric spark caused by unreliable cabling. Moreover, HDCVI 3.0 support POC. Therefore, the cameras can be powered by existing coaxial cable, instead of directly powered by power supplies. This can remarkably enhance the electric safety capability at reasonable cost.
FUD at its finest.
