Passive GPS Tracking
Provides in-depth offender monitoring

What is Passive GPS Tracking?
Similar to active GPS, passive GPS tracking is also a system for monitoring an offender's movement and compliance data 24/7, anywhere in the world. Each STEALTH TRAC passive GPS device continuously records location data throughout the day and is programmable to remember zones that are off-limits (schools or a spouse's residence, for example). Each unit can also remember the areas an offender is required to be in at certain times (at work from 8:00 AM to 5:00 PM and at diversion sessions on Tuesdays from 6:00 PM to 7:00 PM, for example). If the offender isn't compliant to these parameters, STEALTH TRAC's passive GPS unit will note a violation.

A passive unit transmits updated tracking information less frequently than an active GPS device does - normally at the end of the day. Authorized personnel can then see updated information once the data has been transferred. Most passive systems transmit data over regular phone lines rather than through cellular networks. This ability to utilize land-lines is necessary for many agencies covering rural or remote areas where cellular coverage may be inadequate.

Passive systems also cost less than active systems and are ideal for agencies that don't require immediate notifications.

How does it work?
Our passive GPS unit tracks the individual every 10 seconds and remembers the person's boundaries and stipulations as set by the government agency. STEALTH TRAC's passive unit also has an on-board processor which immediately detects and records when the individual is in violation, but the passive unit doesn't contact the data center at once. When the offender places the unit in the charging base (usually when he returns home for the day), the unit calls our data center and transfers the day's information. The corresponding officer can then use any PC connected to the Internet (no additional software required) to connect to tracNET24 and access offender tracking, violation, and compliance information.

Since tracking points are recorded every 10 seconds, criminal justice personnel can review animated offender movement in the finest detail possible, complete with time/date stamps and velocity information. This is extraordinarily useful when an offender is in a vehicle and can dramatically change locations in less than 60 seconds.

Does it save you time?
Absolutely. Since our passive GPS system is exception-based , it streamlines your workload, rather than adding to it. Our system only gives you the information you find helpful.
