I found an Audio-Technica video switcher, model AT-SW1, while organizing the parts storage. This device automatically switches between two video inputs using a timer. Input 1 can be set to 5 seconds / 10 seconds / random, and Input 2 can be set to 1 second / 2 seconds / 4 seconds. If Input 1 is set to 5 seconds and Input 2 is set to 4 seconds, Input 1 will be displayed for 5 seconds, then Input 2 for 4 seconds, and this cycle will repeat. It's for 12V vehicles. I'll upload photos of the packaging, so please check them on a large screen like a PC. I bought this for displaying a multi-camera system, but it ended up unused. Since it's been in storage for a long time, I tested it before listing it, and it works perfectly. The included items are the packaging, the main unit, the instruction manual, and double-sided tape. The plastic packaging is thick, which will increase shipping costs, so I will send it without the packaging. The condition is almost like new, as I only tested it for functionality. 251219-z1
