I'm using a dash cam no brand name made in China in my heavy truck on the road recording cycles and when i'm parked for cargo/diesel theft; i paid approx 100$, but works well, good quality video, has motion sensor and infrared for night; cigarette lighter power cord charging battery. This comes with 2GB card, but with 32GB is recording over 36-48 hours cycles.Imop,would work in house also, smaller than a pack of cigarettes can hide it anywhere.
