I accidentally purchased this item, and although I've opened the bag, it's unused. I bought it for around 1500 yen. It's specifically for the camera CMS-HC72 HC73 and compatibility with other models is not guaranteed. This is an extension cord to connect between a security camera and its power supply. It's made in China, but the company ELPA seems to be a Japanese company. Returns and exchanges are not accepted, so please check the photos before purchasing.
