If you decide to do motion detection on the NVR AND continuous recording, you get a solid blue timeline. No way to see events other than "alarms" which are a joke being you have to keep the app open. Hikvision needs to check out how Blue Iris does alerts on mobile (just one example of whats better on Blue Iris). One guy develops that app and accompanying PC software. Im sure Hik being a large manufacturer could do better if they invested appropriately. You can have great hardware all day but if what you use to interface with that hardware is lacking OBVIOUS features, you leave customers feeling duped into a half-baked system. I wish they would investigate what other apps can do these days, take notes, and bring the software side up to par with their hardware because their cameras are truly great.
