You can verify if your PS4 Camera can see your controller's lightbar by using the PS4 camera setup tool on your PS4 under:
Settings > Devices > Playstation VR > Adjust Playstation Camera
When you see the video feed from the camera, make sure you can see both your PSVR headset AND your DUALSHOCK 4 controller from your seated gaming position. The image below is an example where the headset would be tracked correctly but NOT the controller. In this example, the PS4 Camera is too high and would need to be moved/lowered for the proper tracking to occur during gameplay.
