This system employs an electro-magnetic subject disturbance theory determined by two unshielded coaxial cables.[19] The transmitter emits constant radio frequency (RF) Strength together a person cable and also the Electrical power is acquired by the other cable. Once the change in subject strength weakens mainly because of the presence of an item and reaches a pre-established reduce threshold, an alarm affliction is generated.
