Sensors I use

These are the sensors I use. 

I think of each one as different tool and use the tool for the job.

Cognisys scout is a sturdy programable motion sensor system. Its a beam break system that allows precise camera focusing.

Camtraptions make a great motion sensor system. I use their sensor and flash triggers all the time.

Phototrap sensor by Bill Forbes is an easy plug and play system. I use the Phototrap all the time. He now has a day night switch I love.
