How to keep light on while there is continuous motion

My wired ring floodlight turns on fine when it initially detects motion, but then turns off even while motion is still going on in range of the sensor. Then about 10 second later it comes back on and then turns back off following that cycle. How can I get the light to stay turned on while there is continuous motion in front of the sensor?As a specific example, the light is pointed at our back deck. When people are sitting on the deck I want the light to stay on, constantly picking up that there is motion happening. But instead what is happening is the light only stays on for 60 seconds, turns off, and ~10 seconds later it picks up the same motion again and turns back on in a never ending cycle.
