Behavioral Video for Correctional Facilities

Assessing and validating the physical locations of inmates within a correctional facility or jail can be a difficult challenge but is critical to the public safety of both the facility's inmates and staff. As inmates move through the facility, monitoring their movements requires constant vigilance by corrections officers to accurately and completely identify individual prisoners: By sight as they pass through security posts, by frequent telephone and radio communications between officers at two or more security posts, with paper passes authorizing inmates' movements, and with dry-erase or clip boards with handwritten records to note when prisoners left one area and entered another. Video surveillance systems are essential in providing effective security enhancement in prisons and correctional facilities. State-of-the-Art advancements in video surveillance technology are enabling facilities already utilizing video surveillance to upgrade to more comprehensive monitoring technology that increases the level of safety for both inmates and staff.

PLE is developing a system for unattended continuing surveillance to provide a work-force multiplier that automatically alerts a breach of security inside or outside the wire. The behavioral video system provides alerts and corrobrative evidence to deal with inmate on inmate or inmate on staff violence. It can be used to continually monitor inmate movements and perimeter zones for incoming illegal contraband.

AVT234© deals well with targets being obscured by other objects, particularly in the presence of non-stationary noise sources such as trees blowing in the wind, lapping waves on the shore and sun glints on a barren desert for perimeter and border environments, and in the presence of rapid illumination changes due to clouds moving across the sun. Intruder detection is provided by AVT234© using TMC to perform pixel foreground/background segmentation while TTM groups coherent foreground pixels over time into traceable targets. Once TTM tracks a consistent target for a minimum frame threshold, a detection alarm is raised signaling an intruder.
