Hi, I have IPC-HFW5231E-Z12E 2MP (12x zoom) and IPC-HDW5231R-ZE IP (5x zoom). I will reference them here as 12x or 5x zoom so I can type faster. The 5x zoom works flawless with motion detection and sending me alerts. The 12x doesn't seem to work? I have set the 12x zoom to have the same settings as the 5x zoom but motion still doesn't work in that when something passes in between zones, it should send me an alert. The night vision of the 12x is awesome! The 5x zoom has some minor issues that I need to fix but that is for another thread.
