It seems the cameras stopped working, so they are no longer in use. Since I haven't confirmed their operation, they are being sold as junk items. No claims and no returns, please. Due to the weight, I cannot send everything at once. If you are interested in purchasing, please contact me. In that case, I will relist them in separate listings, or I will list them individually.
