What Is an Ankle Monitor?

An ankle watch is a wristband-like device that sends data about the wearer’s health to a monitoring center located in a remote location. The information is usually relayed through radio transmission or global location systems (GPS) technology.

Ankle monitor system

Certain models have sensors built in that notify authorities if the user attempts to take them off or interfere with their function. The fact that they cannot be removed is a factor for the monitor’s other name the tether.

Applications of Ankle Monitor

One of the most popular applications for ankle monitors is to supervise the location of the wearer. It is usually needed as the wearer is either under house arrest or has been released on parole. In either case, using monitors can eliminate the need for continuous supervision of the perpetrator by the police officer.

Certain studies suggest, however, that the use of monitors might not be as efficient in preventing further criminal acts from the person who wears them in comparison to others rehabilitation programs.

Ankle Monitor Use

Another common use of this ankle monitoring device is the evaluation of the consumption of alcohol. In this instance, it analyzes sweat to determine if it is contaminated with alcohol. Most often, this kind of monitor is employed to determine if the person who wears it has been found guilty of committing a serious alcohol-related violation, like driving under the influence. An ankle monitor could be used as a sanction or rehabilitation tool that stops the person who is in violation from drinking alcohol for a specific amount of duration.

How Far Can You Go With Ankle Monitor?

The first is the distance technology allows. The majority of receivers have the ability to transmit data of fifty and 150 yards. A lot of systems require wearers to be within 25-30 feet of the unit at home for upload and transmit data at certain time intervals.

The judge ultimately decides the allowable distance. The allowed distances are determined dependent on the requirements of the person wearing it and the motivation behind the wearer’s monitor. A lot of cases are classified as house arrests.

If the person does try to leave the court-approved zone, the ankle monitor warns the wearer and alerts the appropriate authorities.

Certain ankle monitors allow wearers to travel out of the house. In these cases, judges determined that the wearer must be able to travel to other locations. They could be:

  • transporting from and to and
  • going to church services.
  • taking part in prison meetings, court appearances or parole hearings
  • leaving to receive medical care
  • receiving rehabilitation services

Who monitor the location of the bracelet know what time and where it is. For emergencies and unexpected occasions, the wearer is generally required to notify those responsible and get authorization to depart.

If the primary reason to wear the ankle bracelet is for control of alcohol consumption. In this case, the wearer is free to move around freely if they refrain from drinking alcohol. The situations aren’t common, however, because most alcohol monitors are still in place and restrict the wearer’s movements.

How Do Ankle Monitors Work?

The people who qualify for house arrest typically committed a minor or non-violent crime. A few offenders can be released for good behavior even after their sentence has been completed. An ankle bracelet could be a condition of the release. Sometimes parole officers will also use ankle monitor bracelets to release parolees.

Surveillance agencies

If the judge assigns an ankle monitor watch to a person typically, the judge will set the monitor’s calibration to limit the wearer’s activities to a specified geographic area or to a particular alcohol consumption threshold. Based on the way in which the monitor is installed, it will notify officials or surveillance agencies if it:

  • Wearer leaves the designated area
  • Unit requires charging
  • Wearer attempts to take off the item, modify it or protect the device
  • The bracelet is able to detect the presence of alcohol
  • System malfunctions

Most monitors relay some form of location information. Certain models are more specific than others and certain devices can detect and relay various items. Some bracelets transmit data continuously and others keep track of data on a specific schedule.

Types of Ankle Monitors

There are three kinds that ankle monitoring devices come in. All of them can monitor the whereabouts of the wearer however, they differ in the way and the manner in which they do this and the information they transmit. The type of wearer is dependent upon the type of the crime(s) and the motive for the monitor, the limits set, the amount of travel permitted, and the kind and quantity of information required.

1. Radio Frequency (RF)

The RF monitors function by informing those who are monitoring them about the location of the device with respect to the unit at home. They generally do not provide an exact location rather, they notify users when the device enters the range of or leaves a specific zone. They are typically used in curfew situations and instances of house arrest in cases where the person is expected to be at a particular area at certain dates and times.

2. Global Positioning System (GPS)

GPS ankle monitors provide specific geographic coordinates that the user can use. They’re typically extremely precise and are able to transmit location information regularly or in regular intervals. They are helpful for individuals who want to move in accordance with pre-planned timetables. They also prevent certain offenders from being close to certain areas or individuals.

3. Secure Continuous Remote Alcohol Monitoring (SCRAM)

SCRAM systems can also monitor locations, too, but their main function is to identify alcohol. They regularly test wearers’ sweat for alcohol levels and provide the results to the organization that monitors it. SCRAM devices are typically utilized in repeated DUI (DUI) instances.
