Hi Picers!!

I want to use this motion detector for security purposes (detect human motion)

When putting a fresnal lens over the PIR Motion sensor it increases the detection distance.

Without the lens I will get about 10 feet detection distance and with it about 20 yards.

My question is, will the motion detection be more reliable without the lens if I only need 10 feet detection distance?

Thank you very much!!
