iPhone TV doorphone set: Main unit JL-1M and entrance unit JL-DA. This is an intercom with a monitor and call function, with adjustable volume and brightness. - Model: Main unit JL-1M Sub unit JL-DA - Accessories: Mounting hardware - Functions: Monitor, call function - Volume adjustment: Volume adjustment button available - Brightness adjustment: Brightness adjustment button available This is a used, working product. There are no noticeable stains or deterioration around the camera. Overall, there are fine scratches, dirt, and discoloration. I have checked the sub unit's call function, communication with the main unit, LED lighting, etc., and they are all working normally at this time, but I cannot guarantee future operation. Everything in the photos is included. The connecting wires were attached for the operational check and are not included as accessories. The power cord for the main unit is different from the original one (new condition). Please understand that there may be oversights or misunderstandings due to my amateur assessment. If there is a discrepancy between the photos and the description, the photos take precedence. Please take a good look at the photos and description and make your decision after careful consideration. Please refrain from purchasing if you do not understand that this is a used item or if you are looking for a beautiful or complete product. No returns or refunds. Thank you for viewing.
