SMART® ACTIVE TRACKING
System Overview
Pro Tech’s Wearable Miniature Tracking Device (WMTD) utilizes GPS satellites to establish an
offender’s location by utilizing the cellular network to transmit the data.

WMTD Communication and GPS Point Storage
• The standard WMTD call-in interval is once every hour while in compliance
• The WMTD will call Pro Tech as soon as a violation occurs, if a Contact is selected
• If the WMTD is not able to make a call because of poor cellular coverage, it will
continue trying to call in until it is successful
• The WMTD collects a GPS point every minute. If a Geographic Rule is in violation,
the WMTD will collect a GPS point every 15 seconds.

WMTD Indicator LEDs
There are three LEDs on the top of the WMTD, identified as Power, GPS, and Zone. The three
LEDs work separately and provide the offender with information. It is possible for any LED to
be flashing Green or Red and it is acceptable for the LEDs to be off. The WMTD will vibrate to
provide an indication that the offender must look at the LEDs. The LEDs function as follows:
PWR Zone
GPS
PWR LED
• This LED indicates the condition of the WMTD battery.
o LED off and WMTD deactivated: Acts as a battery indicator during the activation
process when the Alert Button is pressed
o LED off and WMTD activated: The WMTD is in power save mode
o LED blinking Green: The WMTD is either activated or in the process of being
activated. The battery does not need to be charged
o LED blinking Red: The WMTD is activated and the battery requires charging
• When the WMTD is connected to the charger, this LED will be solid (not flashing) Green
or Red.
o LED Red: The WMTD is not fully charged and should not be disconnected from
the charger
o LED Green: The WMTD battery has been completely charged and the charger
may be disconnected
GPS LED
• LED off: In normal condition
• LED flashing Green: It will flash in unison with the flashing “ZONE” LED during
activation
• LED flashing Red: Indicates a Motion No GPS warning or violation
ZONE LED
• LED off: In normal conditions
• LED flashing Green: It will flash in unison with the flashing“GPS” LED during
activation
• LED flashing Red: Indicates an Inclusion or an Exclusion Zone warning or violation

Rule Definitions
Hardware Rules
WMTD Battery
• The battery is getting low and the device needs to be charged. The device must be
charged for a minimum of two hours daily (the hours do not have to be consecutive).
When the battery needs to be charged, the device will vibrate three times
consecutively and then once every ten minutes until connected to the charger. During
this time, the Power LED will blink Red.
Motion No GPS
• Occurs when the WMTD has accumulated 10 minutes of motion in a 60 minute
period without receiving a signal from the GPS satellites. The device will vibrate
three times consecutively and once every ten minutes until the violation has cleared
by acquiring GPS. During this time, the GPS LED will blink Red.
WMTD Strap
• The strap has been compromised or removed from the WMTD. There will not be any
notifications to the offender that this has occurred, unless the officer selects the
Notify Offender with Vibrate option on this rule.
WMTD Alert Button Pressed
• When pressed, this button sends an alert to the contact. If the offender presses and
holds the button for one second, a single vibration will occur. This will also send out
a notification to the contact(s) specified on the rule.
WMTD Unable to Connect
• It has been over 2 ½ hours since the WMTD has contacted Pro Tech. This is normally
due to poor cellular coverage in the area. The offender is not notified of the Unable to
Connect. Once the WMTD is able to use the cellular network to call in, it will report
the violation and download all tracking data.
WMTD Tamper
• The WMTD has been compromised in some form. There will not be any notification
to the offender that this has occurred, unless the officer selects the Notify Offender
with Vibrate option on this rule.

Rule Definitions Cont.
Geographic Rules
Zone Rules- The offender has violated a Zone set up by the user. The device will vibrate
three times consecutively and once every ten minutes while still in violation, if the Notify
With Vibrate feature is checked. The Zone LED will blink in Red.
• Inclusion Zone
o Geographic areas like home, work, or school where the offender is confined
during an officer defined schedule
• Exclusion Zone
o Geographic areas used to define off-limits areas to the offender
