The Hollyland Mars M1 Enhanced is a 5.5-inch all-in-one wireless camera monitor that can work as a video transmitter, a receiver or a plain on-camera monitor, letting a small crew build a wireless video link from two units instead of a separate transmitter, receiver and monitor. In transmitter mode it accepts HDMI 1.4b and 3G-SDI inputs (with HDMI loop-out) at up to 4K30 on HDMI or 1080p60 on SDI, sending H.264 video at 12 Mbps in the 5 GHz band with about 0.08 s latency and up to 150 m (450 ft) line-of-sight range. In receiver mode it outputs HDMI up to 1080p60. The 1920 x 1080 touchscreen is rated at 1,000 nits with 1000:1 contrast, and the unit offers a 3.5 mm headphone jack, USB-C for updates, DC in/out and an NP-F battery plate (7-16 V DC in). It measures 152 x 96 x 40 mm and weighs about 400 g without antennas. The single-monitor pack includes the monitor, two capsule antennas, a screen protector, OTG adapter, D-Tap to DC cable and manual. Check that 5 GHz bands are permitted locally.
