That does sound shit, sorry you've had that experience!

But I believe lidar should be able to do the same as a camera in terms of real-time updates - from a tech point of view it's just a different type of sensor to a camera, there's no reason (other than difficulty/cost) why lidar robots can't be constantly scanning & understanding the difference between a chair that you've moved since 5 minutes earlier and a cat that keeps moving. Both camera and lidar products can be made dumb enough to fail badly, or smart enough to do a great job. After all, self driving cars have been demo'd using full lidar, it's not like that technology itself takes hours to image a room.
