Hollyland Cosmo C1 300m 無線 SDI HDMI 影像傳輸套組

Got it working on my first try with a rental kit on set — the 300-meter range is no joke and the signal stayed clear even through two concrete walls. Was worried about pairing but the SDI input locked instantly, making the whole setup feel seamless.

Used it on a live event shoot this weekend, and the 300m range was a lifesaver when the camera was on the far side of the venue. The video stayed crisp at 1080p60 with zero noticeable lag, even through a couple of walls. Definitely getting another one for my next job.

Bought this for a doc shoot where we needed to move around a lot, and the 300-meter range let me keep an eye on the monitor from across the parking lot. The video stays crisp at 1080p60 with zero noticeable lag, even when I walked behind a thick concrete pillar.
