GoPro HERO4 Exclusive Timecode Synchronization System Rare item with few listings. This is a peripheral device that synchronizes timecodes through wireless RF signals emitted from multiple GoPro HERO4 cameras. By setting one GoPro as the master and the others as slaves, synchronization is achieved, avoiding risks such as "wanting to shoot one video with several cameras, but experiencing synchronization issues during editing." By connecting via :pulse to the B:LINK Hub dashboard and using the SyncBac PRO, you can remotely control and monitor multiple GoPros from smartphones, tablets (iPhone, Android, etc.), Macs, or Windows PCs. By connecting, you can remotely adjust camera settings, start and stop recording, and even extend the GoPro's battery life, especially when gear-mounted or in situations where operation is impossible. Honestly, this is a product for professionals, but it was quite convenient. It was a high-end peripheral device that cost around 40,000 yen when I bought it. I used it in the past, but I have no use for it now. (I've already sold my GoPro HERO4) As for the operational check, I've confirmed that it starts up with the included USB cable and connects to a PC, but I can't confirm anything further since I don't have the main unit. However, it was working properly back then. The main unit had undergone hydrolysis, so I wiped it with alcohol to remove the stickiness. However, it's not exactly clean, so I've marked the product condition as "has scratches and dirt." ※ This is a peripheral device exclusively for GoPro HERO4. Please note that it is not compatible with other series. You can purchase it anytime, but it might be difficult to use if you don't have the knowledge. Please understand that this product is for those who can understand timecode synchronization without needing an explanation. I cannot answer questions about how to use it (I only have a basic understanding from the past). #GoPro #HELO4 #TimecodeSync #SyncBac #Pro #TimecodeSystems #SPR01
