Wireless Video for Sound Cart- Does 2.4Ghz Video Transmission interfere with Camera Dept operating on 5G?

[jslocationsound]

For years I've been hardlining my video feed to my cart, not wanting to get into the every changing wireless video and congested 2.4Ghz 5G frequencies used on busy sets. 

 

Many Sound Mixers I've worked with have tried to purchase wireless video solutions (Vaxxis, Hollyland, etc.) to be told be camera to turn them off because they think it's interfering with their equipment (which it very well might be if it's frequency hopping).

 

 

I'm pretty new to 2.4Ghz/5GHz on set as none of my current equipment runs on these bands, so here's my question:

 

I just purchased a DJI SDR Transmission Combo, with the understanding that the bandwidth it transmits is much lower then a Teradek/Vaxxis system (although lower res then what camera transmits which is fine for a Sound Mixer). On the DJI, I can set it to a 2.4Ghz frequency and turn off frequency hopping so it's not competing with the Teradeks for frequencys.

 

All the camera equipment on our set is operating on 5G, if I have a frequency set in the 2.4 range, can it cause interference with their equipment in 5G? 

 

 

I've tried doing some research but haven't found an appropriate answer.

 

Thanks,

I use the Accsoon Cineview transmitter which has both 2.4 and 5g. I can hard set a channel on my transmitter which I normally park towards the upper end of the spectrum. I also have an amp which boosts the signal even more for those frequency hoping pieces of camera gear. I park my Zaxcom Zaxnet signal at 2475, with antenna and amp and let camera know to go no where near it as they will not win that battle. If they don't want me to run wireless I just say then provide me with a signal from "Insert wireless system they have, Q-take, Teradek etc"... Otherwise sorry.. Also, electric has recently joined the battle for frequency dominance and enjoy throwing these illegal, high power overseas WIFI boosters that will oblitirate anything on or near it's channel.. Really good fun..

Our amazing utility figured out the way the Accsoon SE works is that you can select the 5GHz channel with the side wheel control but it will just select a 2.4GHz channel on its own on boot up and there’s no way to lock it on a certain 2.4 freq. But we don’t think that it frequency hops once it’s up and linked so it should be possible to work with other systems. The Accsoon user manuals are mostly useless.  These are so cheap and work well enough that everyone seems to have their own now including video assist and script. 
 

Don’t leave your BNC at home though…

I have the Accsoon CineEyes Pro. It works really well and works at a greater distances than my friend's Teradek Bolt. 

 

When I am shooting House Hunters, the producer is able to see my video feed on the second floor when I am in the basement. The other DP has a Teredek and more often than not, the producer has to be on the same floor as him in order to get a reliable signal. 

 

But, the Accsoon sometimes interferes with some Bolt receivers. I don't have a field spectrum analyser capable of scanning 2.4 or 5 so I can't tell what is what scientifically. 

 

I can recommend Accsoon. I have had my unit for 5 years. When the transmitter display backlight stopped working they replaced the hole display free of charge. Outside of warranty.
