UM-600B and UM-600BGSM
GSM/RF Home base unit with built in motion detection tamper sensor

Tamper Proof Strap Mount GPS/GSM RF unit, with battery saver circuitry


The UM-600 GPS tracking set is designed to be used in applications where an offender or Alzheimer movement requires outdoor monitoring.

Passive/Active Offender GPS tracking system comprises a UM-600T GPS bracelet unit containing GPS/GSM and RF transceiver, and a UM–600B or optional UM-600BGSM home based transceiver unit designed to communicate by sending supervisory RF signals to UM-600T. The home base unit containing G force accelerometer/motion detection circuitry to ascertain subject to be monitored does not carry away the UM-600B or UM-600BGSM home base unit.

The UM-600T is easily mounted on offender’s ankle by use of an optical strap (patented) to prevent tampering or removal of unit. The UM-600T upon detection of strap tamper it reports to a monitoring station via unit GSM cellular modem or RF transmitted signals. UM-600T contains a built-in in microphone for the monitoring station be able listen during an event.

The home base unit has adjustable range sensitivity from 10 meter (30 feet) to 100 meter (300 Feet) radius. If the subject carrying UM-600 leaves the home base dedicated area the base unit will generate audible alarm. The UM-600T unit due to communication loss with the UM-600B or UM-600BGSM it automatically “powers on” internal GPS receiver/ GSM modem (Patent pending) to provide automatic GPS tracking signals to a monitoring station PC, PDA, Smart phone, by SMS or GPRS data containing longitude /latitude information relating to subjects location.

UM-600T contains low power RF transceiver which is used to communicate at time interval (every 1 min) with the UM-600B or UM-600BGSM home base unit, to determine subject to be monitored is present at a dedicated location.

UM-600T benefits from the (patent pending) stand by battery power circuitry, which it’s internal circuitry turns “ON” the GPS/GSM circuitry power automatically only when subject to be monitored moves away from the home base unit, to provide user less frequent battery charging.

The UM-600B-GSM home base unit having additional GSM modem, which provides two way cellular communication with monitoring station or others, such as when offenders leaves the home at a time which is not allowed to leave the home, listen in to mode, report of home base unit tamper, GPS bracelet unit tamper, or Bracelet low battery condition, A/C power fail and restore, upload-able menu etc. And in addition the unit provides user two number to call for Emergency assistance need, by user pressing one of the two buttons or by using a wireless emergency pendent Transmitter unit, which will provide two way hands free voice function.
