Solution for Smart Prisons. Investigation of crimes

Rapid detection of suspicious and illegal actions or criminal intent to ensure the people's safety and prevent crimes inside prisons


Smart prisons are also known as correctional facilities that leverage advanced technology to improve security, manage inmate behavior, and enhance rehabilitation efforts. These kind of facilities could use a combination of surveillance systems, biometrics, data analytics, automation, and communication networks to monitor and manage properly inmates and prison operations.

Inmate tracking and identification: facial recognition and fingerprint scanning can be used to accurately identify and track inmates when they enter, moving inside and exit the prison, during headcounts, and when they access different areas of the facility.

Visitor identification: identify visitors entering the prison. This can help ensure only authorized visitors trespassing, and it can also prevent the use of false identities or phone calls control to prevent smuggling into the facility.

Access Control: control access to different areas within the prison. For instance, only authorized personnel can access areas such as the control room, medical facilities, or storage areas.

Medical Identification: can be used to accurately identify inmates during medical procedures, ensure that the correct medication is administered, and prevent medical errors.

Biometrics in smart prisons refer to the use of unique physiological or behavioral characteristics of individuals for identification and access control purposes within a prison environment. This can include features such as fingerprints, iris patterns, facial recognition, voice recognition, or even DNA analysis.
