I have a product: It is a front and rear car surveillance camera. 70mai Dash Cam 4K A810S HDR Set The camera features 4K Ultra HD recording resolution and uses a sensor to deliver superior image quality, especially the Sony STARVIS 2 IMX678 in low light conditions. The set includes a front camera, a rear camera, and the product supports features such as HDR night vision and built-in GPS. (Contact privately, and please only serious buyers. The device is still in its original packaging) I bought it for 750, and the reason for selling is the lack of need. The car broke down before I could install it.
