Circuit is equal to the supply voltage through a relay to switch the remote shutter release. Remote to switch the camera to capture objects moving through the beam.
Doiwongchon will pay an equal pressure distribution over the face touching the relay to a remote shutter release thotwit to the thotwit order, a camera, shoot the object moves through beam.
The circuit will be equal to Voltage Source via a relay contact on the remote control to switch the remote control to switch to a loud shutter Camera to take a picture through a beam moving objects.
