Since the sensor has a certain operating power, it does not work as well on very high doorways (>10ft) or in direct sunlight. Also the field of view cannot cover a very wide doorway (>8ft). Obstructions, reflections, and odd room geometry are common problems, but they can often be solved in software/configuration. Within spec, the algorithm does well tracking 8+ people at a time, and even when a line of people extends through a doorway we usually don't have to track more than that.
