I use Milestone XProtect Essentials and the Firefox (28) web client works fine for me (So does Internet Explorer 11). Phil Schaadt

Your comment regarding flicker is going in the right direction. However it is really about the simplifying the arithmetic of displaying an image at a digital display that has a refresh rate of 60 Hz. With 20 FPS, each frame is displayed three times on the display since 60÷20 is three. 25 FPS does not give an integer value for a 60 Hz refresh rate.

I have about two dozen Chinese Hikvision from Wrightwood and just upgraded them all to 5.1. I'm not using any exotic features but I have not noticed anything flaky with this firmware. I get 20 fps at 3mp resolution Go to Image Menu and expand "Video Adjustment" and set "Video Standard" to 60HZ

Carefully consider the total PoE power capacity per port as well as the total power capacity of the switch. The IEEE PoE Class 3 (IEEE802.3af) standard max is 15.4 watts per port. For example, the Acti KCM-5211 with a zoom lens consumes 10.8W. The small Hikvision Bullets are about 7 watts each. A PTZ may use the PoE+ standard (IEEE 802.3at-2009 PoE standard which provides up to 25.5 W of power) or require its own PoE injector Not all 8 port PoE switches have a beefy enough power supply to feed 8 PoE ports simultaneously at even the 15.4 watt per port specification. I happen to use Ubiquity Tough Switches but layout your actual camera power config before you buy a switch Phil Schaadt
