Ihave my cam set at 4 minute intervals and on numerous nights I have multiple pictures after the flash. doesn't seem to bother them much. What I have seen is right before dark I had some come in and my cam has a flashing red led on the front. A large doe was spooked when it got close to the cam and I could not figure out why untilI figured out the red flashing LED was spooking her. Idisconnected the red LED.
