Great test...
Any thoughts on why the IP camera version of h.264+ (daytime) is 6x more efficient than the DVR version? Is it added noise from the cable? Can the parameters be set identically in both?
Just curious, is most of the wire spooled?

Interesting to see the length of cable runs improving. I don't see as noticeable of smearing as anticipated at the 1500' length. Would/does RG-6 lessen the smearing and increase the usable distance?

Is it the cameras that are limited to 15fps or the DVR?

The Dahua IP camera's day bit rate is 10% of that of the Hikvision. Is there any picture quality compromise with compression artefacts when high levels of scene change occur?
