I knew i should have mentioned that but, the other 3 cameras don't have a light source near them. In fact, the camera in the backyard has close to zero light....and all of them have that same snowy look. I know these aren't high dollar cameras but Swann is a respectable entry level brand....the grainy night vision is basically useless on these though. Do cameras lose "something" over time? I feel like it has gotten bad over time, that it wasn't always like this. Any other suggestions? Or do i ditch this for something new? And if i replace, is there anything out there that's budget friendly, maybe less features, but with decent nigh vision? Thanks for the reply
