Using an autonomous version of the sensors in LifeGuard to create a silent and passive electronic tripwire, DKL International Inc. SilentGuard detects only living humans by sensing the unique electric field created by a beating human heart. SilentGuard can be concealed in walls or doorways, or buried underground, and can reduce the false alarms associated with other sensor systems, as part of an integrated perimeter system for military, security or medical use.
