I bought my first security cameras 5 years ago. After a year I thought I was ready for an upgrade but by not doing proper research I made a poor choice. Now I'm ready to try again but hopefully this time I can get it right. After reading though some of the forums it seem that the camera of choice is Dahua. Now I need to figure out which one. My first decision is should I get a camera with auto tracking? I have seen many videos and it seems very useful but does it work and is it practical? My concern is that if there is multiple things going on in a scene that maybe one moving object could pull the camera away from something more important that is going on. If multiple things are moving will a Dahua camera keep everything in view or will it choose one of them and start tracking it? I have read reviews on other cameras with auto tracking and people say they turn it off because its unstable or just doesn't work. Is Dahua tracking good? What is the general thought on auto tracking?
