Hollyland Mars 400S PRO Video Transmitter Receiver

You can expect a latency of less than 0.08 seconds, or 80 milliseconds. This is generally fast enough for real-time monitoring without noticeable lag for most professional video production workflows.

The transmitter features both HDMI and SDI inputs, but you should use one or the other for your video source. The receiver also provides both HDMI and SDI outputs, allowing you to connect to different types of monitors or recording devices.

The system allows you to connect up to two mobile devices via the Hollyview app simultaneously. This turns your smartphones or tablets into portable monitors, which is incredibly useful for directors or clients on set.

The units are quite flexible. You can power them using Sony L-series batteries for wireless mobility, or use the included DC adapter or a USB-C power source for continuous operation when you are near a power outlet.

The 400-foot range is measured in a clear line-of-sight environment. In real-world scenarios with obstacles like walls, crowds, or other electronic interference, you should expect that range to decrease, so it is best to maintain a clear path between the transmitter and receiver whenever possible.

No, the Mars 400S PRO supports video resolutions up to 1080p at 60 frames per second. It is designed specifically for high-definition workflows rather than 4K.
