V4 Pan Cam Automatically Dimming Spotlight

I recently bought a V4 Pan Cam. I set up an automation to turn on the spotlight. This is in combination with two V3s with spotlight kits. Together they light up my dog Yard nicely and I like to use them instead of my floodlight. However, the V4 will dim after about 5 minutes. I want it to stay on bright. I have to rerun the automation to get it back for another 5 minutes. The spotlight is in manual mode otherwise with the motion sensor off. The automation is NOT the one that has a timer. It is “Turn Spotlight On”. Is this a defect with the camera or is it designed to do this?
