Ankle Bracelets: Monitoring Alcohol, How Do They Work?

how does a ankle bracelet for alcohol monitor work

Alcohol-monitoring ankle bracelets, also known as SCRAM (Secure Continuous Remote Alcohol Monitoring) bracelets, are used by courts and probation departments to monitor individuals who have been ordered to abstain from alcohol consumption, especially in cases related to driving under the influence (DUI) or other alcohol-related offences. These bracelets are typically worn around the ankle for a set period, ranging from 30 to 90 days, and they provide 24/7 transdermal alcohol monitoring by sampling the wearer's perspiration every 30 minutes. The SCRAM bracelet detects alcohol excreted through the skin, even in the absence of noticeable sweating, and transmits this data to a monitoring agency, which can then notify the court or supervising officer in case of alcohol consumption.

SCRAM CAM bracelet: A 24/7 transdermal alcohol-testing device that samples perspiration every 30 minutes

The SCRAM CAM bracelet is an alcohol-monitoring device that can be worn on the wrist or ankle. It is often used by courts and law enforcement agencies to monitor individuals who have been ordered to abstain from alcohol consumption, especially as a condition of probation or parole. The device provides 24/7 transdermal alcohol testing, sampling the wearer's perspiration every 30 minutes.

Here's how it works: the SCRAM CAM bracelet contains a pump that draws in insensible perspiration, which is the sweat that is always present on the skin even when we don't feel it. This perspiration is then tested for the presence of alcohol using an electrochemical fuel cell, similar to the technology used in breathalysers. The fuel cell reacts with ethanol, the intoxicating agent in alcoholic drinks, to detect alcohol consumption. This process is automated, with the device taking a sample every 30 minutes, ensuring continuous alcohol monitoring.

The SCRAM CAM bracelet is designed to be durable and secure, with advanced anti-tamper technology that detects any attempts to obstruct or remove the device. It is also equipped with a GPS locator, allowing authorities to track the wearer's location, which is particularly useful for monitoring house arrest or curfew compliance. The device transmits testing data wirelessly to a base station, where it is stored and uploaded to SCRAM Optix, an online monitoring software. This data is then analysed by trained professionals who review any alerts and report violations to the appropriate authorities.

The SCRAM CAM bracelet is an effective tool for promoting sobriety and accountability. It fills the gaps that exist with other forms of alcohol testing, such as breathalysers, blood tests, and urine tests, which only provide 'narrow-window' testing and can be easily manipulated by drinking or abstaining around test schedules. By contrast, the SCRAM CAM bracelet provides continuous monitoring, making it difficult for wearers to cheat the system and encouraging long-term behaviour change.

GPS tracking: SCRAM bracelets are often equipped with GPS locators to monitor the wearer's location

SCRAM bracelets are often used for offenders who are placed on house arrest or probation. They are equipped with GPS locators to monitor the wearer's location and ensure they do not violate the terms of their house arrest or probation. This feature allows courts and probation departments to keep track of the wearer's movements and provides context to their location data.

The GPS functionality in SCRAM bracelets offers superior location accuracy and long-lasting battery life. It is integrated with Google Maps and Google Info Windows, allowing officers to identify a client's exact location and understand their movements. The GPS data is distilled into clean, easy-to-view information, saving time for clients and officers. The GPS tracker also has a transmission rate of up to one location point every 15 seconds, aiding in client apprehension.

SCRAM bracelets with GPS functionality also have features like Wi-Fi tracking, GPS jamming, and sophisticated detection mechanisms that enhance tamper detection capabilities. The slim, one-piece design is shock-resistant and waterproof, and it virtually eliminates false alerts. The GPS tracker can also be converted to RF monitoring when in range, reducing location and communication alerts and maximizing performance.

While the SCRAM Continuous Alcohol Monitoring (SCRAM CAM) bracelet does not have built-in GPS, SCRAM Systems offers solutions that can be used in conjunction with the alcohol monitoring bracelet. For example, the SCRAM TouchPoint Mobile Smartphone App is a convenient way to stay in contact with clients and can generate a GPS point for every scheduled or on-demand check-in. This allows supervision officers to observe and confirm a client's location.

Court-ordered use: Courts can order the use of SCRAM bracelets as an alternative to incarceration or as a condition of probation

SCRAM bracelets are often used as an alternative to incarceration or as a condition of probation. Courts may order the use of SCRAM bracelets for those who have been convicted of driving under the influence (DUI) or other alcohol-related offences. In some cases, a judge will only release a defendant from jail if they agree to wear a SCRAM bracelet.

SCRAM bracelets are also used as a pretrial condition of release from jail, allowing courts to continuously monitor defendants who are out in the community. This provides an alternative to the costly option of keeping DUI offenders in jail to maintain sobriety.

Courts generally cannot order alcohol monitoring without evidence that the person has a drinking problem or that drinking contributed to their criminal conduct. SCRAM bracelets are typically ordered along with other forms of treatment, such as Alcoholics Anonymous (AA) sessions or classes at a rehabilitation facility.

The offender typically bears the cost of the SCRAM bracelet, which includes an installation fee and a daily monitoring fee. However, in some cases, the court may subsidize or cover the cost if the defendant is unable to afford it.

SCRAM bracelets are worn 24/7 and are designed to detect alcohol consumption and any tampering with the device. If an offender attempts to remove or tamper with the bracelet, the monitoring company will be notified and will report the tampering to the court or probation department. Such actions can lead to severe consequences for the offender, including termination of probation or jail time.

False positives and negatives: SCRAM bracelets can give false readings due to equipment malfunction or certain medical conditions

SCRAM bracelets are known to give false readings, despite being the most advanced devices for transdermal alcohol monitoring. False positives can occur due to equipment malfunction or certain medical conditions affecting metabolism.

SCRAM bracelets sample insensible perspiration every 30 minutes to detect alcohol consumption. If alcohol is detected, three additional readings are taken to ensure the reading is correct and not caused by some other element. However, SCRAM bracelets are sensitive enough to detect very low levels of alcohol, and their high sample rate can provide an accurate timeline of drinking. This can lead to false positives, especially if the wearer has used products containing alcohol, such as mouthwash, cologne, or cold medicine.

False positives can result in serious consequences for the wearer, including termination of probation or revocation of sentencing agreements. It is important to consult an experienced attorney who understands the technology and can challenge SCRAM evidence in court.

Additionally, SCRAM bracelets can give false negatives if the wearer has not consumed alcohol but has been exposed to environmental alcohol sources. However, SCRAM CAM technology can distinguish between drinking and environmental alcohol exposure, providing courts with confidence in the test results.

Frequently asked questions

SCRAM stands for Secure Continuous Remote Alcohol Monitor. It is an electronic device that is worn around the ankle to monitor the alcohol content in the body.

The SCRAM bracelet tests the wearer's perspiration for the presence of alcohol every 30 minutes. It then wirelessly transmits the test results to a monitoring agency or centre.

Courts use SCRAM bracelets to monitor people who have been ordered to not drink alcohol, often as a condition of probation or parole. They are also used for house arrest monitoring.

If alcohol consumption is detected, the SCRAM system notifies the court or a supervising officer, and the offender risks further penalties like more jail time, bigger fines, and prolonged probation.

There is an installation fee and a daily monitoring cost. The installation fee ranges from \$50 to \$100, and the daily monitoring fee can be between \$10 and \$15, so monthly costs can be as high as \$450.
