Inmate Phone and Canteen

As of September 2019 we have switched phone and commissary providers to TurnKey. If you would like to set up an account so your friend or family member can be in contact with you please go to https://team3.inmatecanteen.com/ there you can put money onto an inmates account, purchase commissary products for an inmate for delivery, allow phone calls or inmate messaging and also get set up for video visitation( Note: Video Visitation can only be done at a desktop computer). If you are having trouble setting up an account there is a help section on the above website for you to access help or ask questions.

Video Visitation

Video Visitation must be done from a computer using Google Chrome and an updated flash player. Before starting this process you must make sure that your Adobe Flash player is fully updated and that you are using Google Chrome. So I would set these two things up, restart your computer and then hop on Google Chrome on your desktop or laptop computer and go to https://team3.inmatecanteen.com/ and start the application.

Steps for how to start visiting are below:
-Go to https://team3.inmatecanteen.com/ on a computer (not supported on mobile devices i.e. tablets, cell phones, etc)
-Log in, select your inmate, and select the Video Visit an Inmate option.
-Depending on the facility, you may be required to fill out a form, submit a driver's license picture, and a picture of your face. Once submitted, the facility will either approve or deny it. Once approved you will be all set to video visit!
- Make sure you are allowing flash player to run in google chrome by selecting the lock icon to left of the browser:
-Flash Player needs to be set to “allow”. Then you can refresh the page and it should be good to go. If flash player is being blocked you will not be able to take a picture or see any video during the visitation
When you click on the video visitation link on the website, please visit the Audition Room to test your equipment. To find the Audition Room, please click on 'Video Visit an Inmate' and it will be located on the top of your screen. Here you can test and verify that your webcam and microphone are working. We highly recommend a hard line for video visiting, unstable internet can result in poor visit qualities.
