Electronic monitoring programs help lower public safety expenses for taxpayers by reducing jail populations and requiring offenders to pay for services. In addition, electronic monitoring provides increased public safety by utilizing the latest ankle monitoring technologies and other supervision strategies.

Types of Programs

We offer several unique monitoring programs as described below. To learn more, see our client rules and regulations or monitoring technologies pages.

Benefits & Success

Based on the evidence collected, continuous alcohol monitoring is a viable deterrent for offenders. Of 3,707 people placed in the alcohol monitoring program, only 47 participants have had confirmed alcohol readings and only 85 others have been terminated from the program for other violations. 

Continuous alcohol monitoring is an effective technology for offenders with alcohol-related crimes. It is used on post-conviction cases that involve driving while intoxicated and driving under revocation and/or suspension. Alcohol monitoring is also used in pretrial cases involving alcohol in domestic violence cases, as well as habitual traffic offenses. 

The continuous alcohol monitoring program accepts referrals from the Denver County Court Probation and Denver District Court Probation. The program also works with the Colorado Department of Motor Vehicles. Enforcement hearing officers can refer people with suspended licenses to continuous alcohol monitoring as a condition for driver's license reinstatement.

Currently, alcohol monitoring in our department, uses a device that tests offender alcohol concentration through the skin (trans-dermal alcohol concentration, or TAC). The bracelet is water-resistant and tamper-resistant. The offender is tested at least 24-times per day. If alcohol is detected, the system automatically begins sampling every 20 minutes until alcohol is no longer present. The results are collected throughout the day and stored in the bracelet. The results are uploaded once a day via a modem to the offender's home, or once a week to the office. The results are then analyzed and posted on a secure website, so officers can access the information when needed. If the Defendant attempts to place objects (tape, playing cards, paper, etc…) between the skin and the bracelet to defeat it, the built-in tamper technology will alert the officer.

Benefits & Success

The overall success rate for electronic monitoring programs from drug court referrals is 88%. Electronic monitoring has been a highly effective consequence for offenders as well as a much less costly alternative to jail.

Drug Court utilizes electronic monitoring as an alternative to jail for offenders who are in the Drug Court Program in Denver District court. Most offenders are sentenced to a weekend where they are “locked down” or incarcerated in their home as the jail, utilizing a radio frequency monitor or  the continuous alcohol monitor. Traditionally, electronic monitoring has been used as a sanction by the court for offenders who violate court rules, but it has also been used for longer sentences.

Benefits & Success

The juvenile monitoring program provides parents with an opportunity to help resolve behavioral issues with their child at home while he or she serves their court sanction. Of the 848 juveniles placed on electronic monitoring, with an average stay of 26 days, 96% have completed the program successfully.

The Electronic Monitoring Program works with the Denver County Courts Juvenile Division and Juvenile Probation. The program works with juveniles, their parents/guardians, and probation officers to address specific needs to promote successful completion of electronic monitoring sentences.

The program uses a variety of technologies to monitor juvenile offenders. Most commonly, the juvenile is placed on radio frequency or cell units. Certain types of offenders are placed on the continuous alcohol monitor for alcohol abuse. Monitoring juveniles creates unique obstacles which differ from normal electronic monitoring programs. The courts have very few alternative sanctions for juvenile non-compliance, thus requiring a creative approach to enforcement of violations.

Benefits & Success

79% of the people sentenced for continuous alcohol monitoring through the Colorado Department of Motor Vehicles Enforcement Hearing Division have successfully completed the program, with an average sentence length of 43 days on the program. Some of those sentenced have asked to remain on the program after successful completion to encourage continued treatment.

The Electronic Monitoring Program works with the Colorado Department of Motor Vehicles Enforcement Hearing Division to continuously monitor offender sobriety 24-hours a day. Offenders may be ordered by hearing officers to complete continuous alcohol monitoring as a condition of license reinstatement. Hearing Officers are notified about violations and can choose to either terminate the offender from the program or extend the length of time they must be on the alcohol monitor. Additionally, offenders can choose not to wear the bracelet and be subject to alternative guidelines of license re-instatement set by law and the hearing officer.

Benefits & Success

More than 3,000 offenders are placed in a post-conviction electronic monitoring program each year, with an 89% successful completion rate. With an average sentence length of 38 days, the Electronic Monitoring Program saves the Denver County Jail over 100,000 bed days each year.

Post-conviction cases are the largest of the programs administered by the Electronic Monitoring Program, accounting for 57% of offenders monitored. The Courts utilize this program as an alternative sentence to jail and/or a condition of probation. The offender is required to meet with a probation officer either weekly or bi-weekly to address issues, verify employment, treatment, community service, school, and other court approved activities. 

Post-conviction client monitoring may utilize a combination of technologies. Most commonly offenders are monitored by radio frequency, cell units, and/or continuous alcohol monitoring. GPS technology can also be used and is determined for appropriateness by program staff and the the criminal history of the offender.

Benefits & Success

The success of this program has spawned new programs such as the jail work release, work search and remediation programs.The Sheriff Home Detention Program saves money and resources, and allows offenders to work while on the program. The program diverts non-violent offenders from the Denver County Jail, reducing the number of beds needed and lowering taxpayer costs.

Upon court approval, the Sheriff’s Department can release inmates to the Electronic Monitoring Program for supervision of their sentence. 

Sheriff Home Detention I & II

The original Sheriff Home Detention program allows the Sheriff’s Department to release inmates to the Electronic Monitoring Program. Inmates are then jailed in their homes and are allowed to work while under the supervision of electronic monitoring. This program utilizes several technologies including radio frequency, GPS, and continuous alcohol monitoring. The Sheriff’s Department and the Electronic Monitoring Program review the offender’s history and make a recommendation to the court on the viability of electronic monitoring and the type of technology that should be utilized. 

Jail Work Release

The Jail Work Release program was created to allow inmates to maintain their employment while serving their jail sentence. Offenders are released from the jail daily to work and then return to the jail at night. Currently this program utilizes GPS and continuous alcohol monitoring technology to monitor the inmates. By utilizing GPS and continuous alcohol monitoring, program staff are able to monitor the offender’s movement and sobriety.

Jail Work Search

The Jail Work Search program was created to allow inmates who might otherwise qualify for one of the other sheriff programs to be released from the jail to search for employment. The offender is allowed job search time and then returns to the jail nightly. Inmates are monitored with GPS and continuous alcohol monitoring. If the offender successfully finds employment they are then transferred to one of the other programs to complete their sentence.


The Remediation program serves as a final effort by the sheriff, probation, and electronic monitoring to keep an offender in the community before a more severe sentence is imposed. The Remediation program was created in conjunction with probation to give the court an alternative sentencing option for probation revocation filings. Offenders are initially sentenced to a stay of 30 days in the Denver County Jail and are then placed on monitoring. The Sheriff’s Department then determines what type of monitoring technology is needed, the length of sentence, and whether the offender will be allowed to serve that sentence at home or will have to report back to the jail nightly. This program is designed to facilitate successful completion of probation terms that were not being met prior.
