I am running a video/audio signal from a camera in a lobby to a Blackmagicdesign ATEM switcher that are about 150' apart but cable run will be closer to 200'. The video/audio from the camera in the lobby will be streamed online. My initial design for your feedback... Lobby will have camera with a Hollyland Mars 400S SDI/HDMI Wireless Video Transmission System. Once the signal is at the HDMI rx in the lobby it will output on an SDI port and make a 200' cable run to the Blackmagicdesign 8 port ATEM switcher.
Lobby Camera <--HDMI cable--> HDMI tx <--wireless--> HDMI rx with SDI output <--cable?--> Blackmagicdesign ATEM switcher to the live stream.
Will RG59 75ohm cable work for that 200' run or does it need to be a special "SDI" rated cable? Again, it needs to transmit both the video and audio.
Thanks.
