Ordered these cameras with the highest of hopes. There discription sounded great. When I rec'd them I was delighted. After setting up (very easy) day viewing was ok. Night nothing. Tried all that the seller suggested with no results. Refused new item. Doesn"t work 1st. time I'm out. (no 3 strikes) Waited almost three weeks for return to find that they charged me for the shipping twice. Had to contact Amazon to ajust. Update. They told Amazon it was scratched thats the reason for the double charge on shipping. THEY lie. My suggestion. Stay away.
