Alcohol Monitoring Unit
The HADM application consists of four independent components, all integrated to deliver a comprehensive and effective method of tracking.
- Patented Bluetooth ankle bracelet with continuous alcohol sensor
- Bluetooth enabled wireless handset
- Wireless network for data transmission
- HADM software application
Vigilant Tracking’s House Arrest Detention Method operates on a Motorola Bluetooth enabled handsets through the Sprint Nextel iDEN wireless network. Actsoft software uses Bluetooth technology as the chief communication protocol between wireless handsets and the ankle bracelet. The handset serves as the primary communication device and the Bluetooth ankle bracelet operates as a secondary device.
The handset is responsible for locating, establishing and maintaining a constant connection with the bracelet. As the primary device, the wireless handset continuously queries the ankle bracelet to determine if it is within acceptable range. Based on the level of Bluetooth in the bracelet, the range is approximately 30 feet. Each bracelet HADM a unique 12-character Bluetooth address enabling it to be identified independently.
During the initial fitting of the ankle bracelet, the offender’s baseline levels for various sensor items are set, including:
· Ethanol level to monitor alcohol consumption
· Infra Red to determine tamper events
· Temperature to monitor changes in body temperature
· Battery level to monitor charging requirements
Following baseline configurations, the application regularly monitors each bracelet’s status sensors. A unique feature of the bracelet is a built-in alcohol sensor, which detects traces of Ethanol in a person, indicating alcohol consumption. This innovative element differentiates Vigilant Tracking’s unit from most competitors. The HADM software also has the ability to store events and alerts in a history file. Agency personnel are alerted when an offender steps out of range or violates a condition (e.g. a pedophile cannot go within 2000 feet of a school). The device also provides a voice alert to the offender when the battery needs to be recharged.
