Description

System and method for monitoring prisoners in accommodation facilities using intercom terminals}

The present invention relates to a technology for monitoring prisoners in a detention facility using an intercom terminal. More specifically, the present invention relates to a technology for monitoring prisoners in a detention facility using an intercom terminal installed in the detention facility. It is about a technical idea that enables efficient management of the control area by generating or not generating a re-alert.

In a conventional CCTV video surveillance system, a camera starts capturing video based on a detected item and outputs the video to a video surveillance monitor, and at the same time, an alarm means is configured to perform an audible/visual alert.

However, since unnecessary alarms or malfunctions frequently occur depending on the detection performance or detection method installed in various control areas, the workers who control them often ignore the alarms. As this situation continues, the warnings are often caused by poor control. Unforeseen circumstances may arise.

Also, when there is an access restricted area among the areas under control, and it is necessary to control the people who passed through the area to pass through the area again after finishing their business, it is difficult for the control room personnel to keep an eye on the video of the area where the alarm occurred. In many cases, it is difficult to confirm at the appropriate time whether the person entering the area has left the area within a certain period of time, which may lead to unexpected casualties.

In particular, when a conventional CCTV video surveillance system needs to control multiple access restricted areas, the location where the alarm occurred may be unclear, and alarms may also occur in other areas at the same time, and in many cases, alarms are malfunctioning and require long-time control. As this happens, managers lose concentration, making it difficult to check whether the visitor has returned or not checking due to negligence in work, which frequently occurs.

For example, the control room manager knew that an inmate who was confined alone in a prison cell was going to the bathroom through movement detection and alarm. However, the control room manager, who has to control multiple inmates, saw it as a routine act because it was difficult to keep an eye on only the inmate in question. It was not possible to continuously monitor whether a person came out of the bathroom or not, and as a result, there are cases where fatal accidents occur in the bathroom and are only discovered after a long period of time.
