Can anyone suggest a camera off Ebay,seen someones foot print in snow around my shed.Something under $100 that uses SD card to record...theres hundreds of them on Ebay,mostly from China.So hoping someone can narrow it down a little for me.Dont need wifi one just something that records on card,greatly appreciate any help....AND also one that doent get interence from router,got wireless one off ebay but router scrambles the signal.

Got a trail camera,doesnt take pictures through house window for some reason,just doesnt detect distant movement that way.Windows have UV protection maybe thats why.And the camera I do have doesnt have any ability to record for itself...dont have a dvr and dont want to leave laptop on..so still looking for one that uses an sd or micro sd to record
