function Portal_A_Define_Spawn(pUnit, Event)
    pUnit:RegisterEvent("Lets_Get_Ready_YOERUSOJ", 1000, 1)
end
function Lets_Get_Ready_YOERUSOJ(pUnit, Event)
    pUnit:RegisterEvent("We_Need_To_check_For_players_If_there_Are_teleport", 2500, 0)
end

function We_Need_To_check_For_players_If_there_Are_teleport(pUnit, Event)
    local player = pUnit:GetClosestPlayer()
    if player == nil then
    else
        local PlayersAllAround = pUnit:GetInRangePlayers()
        for a, plr in pairs(PlayersAllAround) do
            if plr:HasAura(STEALTH_ID) == true then
            plr:RemoveAura(STEALTH_ID)
            end
            if plr:HasAura(STEALTH_ID_B) == true then
            plr:RemoveAura(STEALTH_ID_B)
            end
            if plr:HasAura(STEALTH_ID_C) == true then
            plr:RemoveAura(STEALTH_ID_C)
            end
            if plr:HasAura(STEALTH_ID_D) == true then
            plr:RemoveAura(STEALTH_ID_D)
            end
        end
    end
end

RegisterUnitEvent(NPCID, 18, "Portal_A_Define_Spawn")

I quickly pulled this together for you, save it as a Lua file and put it in your scripts folder. At the top change the NPC ID to the npc id to a npc you want to check for stealth, next change the STEALTH_ID's to the spell id's of stealth (theres 4 different ranks I believe).
If it doesn't work tell me, good luck!
