1.Solution::You can directly use the internal red light to focus, but this requires the power supply to have a 24v port. If the power supply does not have a 24V port, you can connect an external 24v power adapter, and the current can be set to 0~3A.  
2.Notes:The thinner the red light, the closer to the focal length.
