Just wait till you move from one eco-system to another, then the fun and games really start.
Seriously, although I have spent an inordinate amount of time dialing the Dahua gear in, the quality of image makes it worthwhile. Haven't had a random reboot in 20 hours and all the IVS events are working as they should.
Now it is time for me to swap out the rest of the Hik gear for good.
Good enough for what I use it for, a narrow area between two houses with ext lighting and no need for ir. If you need good night vision go with the 2mp starlights.
