Keep an eye on Brazilian juvenile rehabilitation

Keep an eye on Brazilian juvenile rehabilitation

Beginning in early 2011, 23 juvenile detention facilities in Rio de Janerio, Brazil have deployed Hikvision Digital Technology both analog and IP video surveillance equipment to help monitor inmates. Local system integrator, Interimagem, implemented the systems consisting of Hikvision Digital Technology IP cameras, mini domes, analog cameras, to meet the different needs of the two different types of facilities, Degase and Criaad. The system integrator worked in partnership with Hikvision official distributor in Brazil, VMI Sistemas de Seguranca.

Degase, the first type of detention facilities was reserved for more serious juvenile offenders. The facility has a higher number of inmates and faces higher risks of violence and vandalism. There are a total of six such facilities located within Rio de Janerio. One of the challenges was preventing inmates from disabling, manipulating or vandalizing the cameras at the low ceiling facility, said Alvaro De Souza, CCTV Manager at VMI.

For indoor monitoring, 2-megapixel vandal-proof mini network domes were installed in corridors and rooms to prevent camera tampering. The cameras come with alarm system that notifies security control room of camera tampering. In addition, 5-megapixel network cameras were placed indoors at key access points and other areas of high importance. The cameras 5-megapixel function reduces infrastructure costs, and could be placed in higher locations to prevent tampering, said Alvaro De Souza.

At Degase, 540 TVL IR bullet cameras housed in IP66 rating enclosures that met Brazilian government's request for weather-proof cameras were deployed for outdoor surveillance. The cameras utilize 40 meter IR distance range, with D/N and automatic color or black/white capability. The final touch to the center's surveillance system was a H.264 compression card. “This card saves on video storage capacity by utilizing the card's motion detection feature with analog cameras, and using an IP camera's internal motion detection ability,” Mr. Souza noted.

The second detention facility, called Criaad, is referred to as a semi-liberty facility used by less-serious juvenile offenders. There are 17 Criaad facilities located throughout the state of Rio de Janeiro and require lower level security than Degase. As with Degase – and for the same reasons – Criaad's primary outdoor cameras were 540 TVL IR Bullet Camera. The detention facility also used a Hikvision standalone DVR. “One helpful feature of the DVR is when a system crash is imminent; an alarm automatically sounds, allowing the DVR to automatically save its video data and information is not lost,” said Souza.

Tying this solution together is Hikvision's VMS – a full platform, capable of controlling not only DVRs and compression boards in the same interface, but also IP cameras. This software can manage up to 256 pieces of equipment (cameras, DVRs, etc.). The installation of the system has curbed and eliminated vandalism, prisoner riots, and other misbehavior.
