Is film replay legal

So, my school would possibly like to use a film replay system for scouting opponents. The device used to record would not be in the driver box, nor the device that is recieving footage. So, my question on this topic is, if the host allows it would this break any of the rules in the vex game rules???

So you would have someone recording matches from where the audience is allowed to be? And you would have a hub somewhere else that is taking in all the information? Nothing illegal about that.

As long as any wireless communication isn’t interfering with the networks on the ground, should be good. But if the robots are at 2.4 and the event is at 5 that doesn’t leave much WIFI left for you… I always ask people at my events to shut off WIFI… So how are you planning on handling the data?

As far as scouting goes, sounds like a lot of work. You would have to have one person recording all of the matches, then someone else handling all the videos that come in.

Or, do you want a reference later in the day of their autonomous routines before you have a match with them? I just noticed you said opponents and not alliances.

Thwre is someone in the audience recording and the footage is being recieved by an antenna thar broudcasts the signal. It is however not wifi, it is a broadcast signal. Think radio waves. It uses 5g braoudcasting to send the footage at the high speed, and doesn’t interfere with the vex server because we can change the frequency channel on the system

Actually we have one person who handles the recording and watching of footage

As mentioned before - check with your Event Partner about wireless transmissions in the competition area. Interference happens not just for robots, but mobile scoring. Just because you are not setting up wifi does not mean you won’t interfere on the spectrum.

That is why we are able to change the channel of the signal so that it wont cause issues.

Yes, but you won’t know if there are issues in the first place unless you are in touch with the event partner. If the tablets go down, as they have done for me in the past, I’m not going to realize that the person recording the match is taking up bandwidth unless they let us know. When they go down I don’t start shaking down people in the audience!

Event partners use the 5ghz WIFI, what do you mean by 5g?
Do you mean ?

There are always people recording matches and I have no idea if they are using wireless.

I would also think about a system where you are using flash drives or SD cards as a backup in case you are having issues. It will probably work better for you anyway.

Not trying to give you a hard time, but when things happen at event we usually don’t have time to keep trying, we just use our backups. So, if my tablets go down, I’ll spend a couple of minutes trying to fix it, but I have to run an event… So we just go to paper. This degrades the quality of the event, takes more time from my volunteers, makes it more likely that we will make errors, and I will have no time to trouble shoot with you as I am running an event. If the EP asks you to turn off your WIFI, it’s because we need you to do it.

As an event partner, I am with @sankeydd on this one. We typically set up two different 5ghz wifi networks. One if for guests and one is what we use for the tournament. In the driver meeting, we typically warn the teams that if anyone is caught broadcasting on any other 2.4 or 5 ghz networks, it can mean disqualification for their team or organization. The guest network is throttled so nobody is doing any heavy usage. We have it there for Vex Via.

We routinely use various sniffers to look for and identify anyone broadcasting. As a result of these precautions, we simply do not have interference issues we have seen at other venues including at Worlds.

Always talk to the EP. 5GHz has a lot of room so it is possible to have this kind of setup and not cause interference, but there might be other circumstances that would make it reasonable for an EP to refuse letting you do this (for example, our networking guy likes auto channel select so you never know what channel the WiFi might switch to in the next moment).

@BottomNotch unfortunately, that is our problem. We have a “netowrking” guy who does not quite understand how all that works so he accepts what the router does for him rather than taking control of the situation. In our type environment, it is rare that auto select will do as good of a job and give as consistent connection as a network that is manually set uo by someone who knows what he/she is doing.
