For sale: Hollyland Mars 400S Pro. Brand new, unopened. This is a popular wireless video transmission system for video production and streaming. It supports both HDMI and SDI, allowing for stable, low-latency video transmission. It can transmit up to approximately 120m and offers excellent image quality. I purchased this but never had the opportunity to use it, so it has been stored unopened at home. The outer packaging hasn't been torn, and the box has never been opened. Therefore, in the event of any initial defects, please contact the manufacturer. It seems this model is currently difficult to obtain, so don't miss this opportunity if you're looking for one. Instant purchase is welcome. #hollyland #ホリーランド (Hollyland) #ホーリーランド (Hollyland) #カメラ (Camera) #新品 (New) #未開封品 (Unopened) #動画撮影 (Video recording) #映像制作 (Video production)
