SCHELL COVERT 4 SERIES SIGNALING TRANSMITTERS FOR CONTROLLED DELIVERIES

The Schell Covert 4 Series Signaling Transmitters are for controlled deliveries and feature credit card sized dimensions for easy concealment. They are capable of being hidden to the extent of being undetectable in a controlled delivery package. The RF transmitter can typically be monitored by law enforcement with existing VHF radios or scanners.

	SCHELL COVERT 4MDLD SIGNALING TRANSMITTER The Schell Covert 4MDLD Signaling Transmitter is a motion detecting/light detecting transmitter that tells monitoring officers the controlled delivery status. The officers will know before and after the box has been opened if the container is moving or still. They will also know immediately when the box has been opened (any ambient light that enters the package will alert the officers).
	SCHELL COVERT 4MDT SIGNALING TRANSMITTER The Schell Covert 4MDT Signaling Transmitter is a motion detecting/trip wire transmitter that tells monitoring officers the controlled delivery status. The officers will know before and after the box has been opened if the container is moving or still. They will know the package has been opened as soon as the trip wire has been broken. A change in duty cycle will alert the officers.
	SCHELL COVERT 4 SIGNALING TRANSMITTER The Schell Covert 4 Signaling Transmitter is a trip wire fired unit only. It will send a beacon transmission to the monitoring officers. When the package has been opened and the trip wire broken, the transmitter will change duty cycle. This signal will immediately alert the officers that the package has been opened.
