Why is Humanoid.seated not working after I reset or get killed in my game?

I am working on a security camera system, however when a player resets or gets killed and sits on the chair again, the stuff that's supposed to happen when a player sits on the seat does not. Why is that happening? I put the script in StarterPlayerScripts by the way.

Local Script:

camera = workspace.CurrentCamera
player = game.Players.LocalPlayer
character = player.Character or player.CharacterAdded:Wait()
humanoid = character:WaitForChild("Humanoid")
securityCams = game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("Security")
remotes = game.ReplicatedStorage.Remotes

humanoid.Seated:Connect(function(seated, seat)
    if seated then
        securityCams.Open.Visible = true
    else
        for _, element in pairs(securityCams:GetChildren()) do
            element.Visible = false
        end

        repeat wait()
            camera.CameraType = Enum.CameraType.Custom
        until camera.CameraType == Enum.CameraType.Custom
    end

    remotes.DisableSecurity.OnClientEvent:Connect(function()
        for _, element in pairs(securityCams:GetChildren()) do
            element.Visible = false
        end

        repeat wait()
            camera.CameraType = Enum.CameraType.Custom
        until camera.CameraType == Enum.CameraType.Custom
    end)
end)
