How do you check what team a player is on using an "if" statement?

function getTeamsColorFromName(name)
    local color
    for _,v in pairs(game.Teams:GetChildren()) do
        if v.Name == name then
            color = v.TeamColor
        end
    end
    return color
end

game.Players.PlayerAdded:connect(function(player)
    repeat wait() until player ~= nil -- This event is not very trust-worthy.
    if player.TeamColor == getTeamColorFromName("Spectators") then
        player.CameraMode = "LockFirstPerson"
    end
end)

Broken down, the function at the top returns the Team's TeamColor from the name of it (Spectators) and then sets their CameraMode.

game.Players.PlayerAdded:connect(function(player)
        if player.Teams == "Spectators" then
            player.CameraMode = "LockFirstPerson"
        end
end)

That should work? I can't test it, RobloxStudio crashes every 1 minute for me.
