Motion sense is quick. It’s a very very good system for the money spent and ease of install. I have no doubt you could spend thousands and get higher image quality etc etc but for the couple hundred dollar price category it’s about impossible to beat. Videos upload to the cloud almost instantly so even if someone’s saw the camera and ran off with it I still have the video of them doing it. We use it to keep track of the kids, which of their friends come over, whether they had their glasses on when they came home or left them at school, etc etc. endlessly handy. We were on vacation in Texas and saw that a relative had left the garage walk in door open and got a neighbor to go close it for us. We know when the mail shows up too.
