try energizer... try without the sd card... your not getting any pics with it so whats wrong with getting 50+ pics without it... also MAKE SURE TO USE THE IR AIM to make sure that the camera isnt pointing into the sky/ground. Looks can be deceiving on where it is aimed... Also go buy a bag of corn and put out in front then set IR aim to ON go over to corn pile and move arm or leg around it. If cam is set a good angle the red light will light up. Go over turn to auto. shut lid... back up wait for light to stop blinking then go by corn pile and make sure cam takes some pics of you then leave for 4 days.. if you do this you WILL have pics given your cam isnt broke or you have no deer in your area....
