This is a Wansview automatic pet feeder with a built-in camera. It has a large 4L capacity for dry food. It supports two power options: a power cable and a backup battery. This is a used item. It was used last year and has been stored at home. Only the power-on function has been confirmed. The box and instruction manual are not included. Only what is shown in the photos is included. Due to being a used item, there may be minor scratches and stains from use. We have cleaned and disinfected it as much as possible.
