For the last 6 months or so, I've gotten color at night (no IR), which has been great. Haven't changed a thing and now it's switching to IR at night, which is unfortunate. A side result of this is I get a motion detection each night when it switches from color to b&w and I'm wondering if anyone has had that experience and if they figured out a way to stop it from doing that. Just curious what the newest firmware that's out on this unit right now (I'm guessing not much, sense there's a newer model). Just curious if anyone with a Mac computer has been able to use live view with a web browser after updating to Catalina OS? I upgraded and locked myself out of that option, unfortunately, as the plug-in no longer works. iVMS-4200 works decent, but live view gets choppy after about an hour of viewing (resetting the image goes back to non-choppy for about an hour). Playback of recordings is never choppy, just live view. Thanks
