Hello everyone. This is my first post and my first security system for my house Its a Swann 8 video NVR Power Over Ethernet. 1080 cameras. Great quality during the day, but night time I am having issues with the quality in certain spots. 2 cameras are facing my driveway and they have a lot of grain (noise) coming from them. DOnt know why. turned them towards other objects and it clears up. Im guessing its just where they are pointed but I need my driveway covered. Any thoughts. NO ARTIFICIAL LIGHTING IS PRESENT. should I buy illuminators, flood lights for my driveway?? I Attached some photos of what I'm talking about. Any tips would help THANKS
