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)

Hey, I'm late on this, but for all the future people who see this:

The answer is because when you die, your humanoid is deleted and a new one replaces it. Therefore, all connections related to humanoid are destroyed. Every time a new character is added, you have to redefine that connection.
