Hikvision secures Greenwood Police crime lab

The solution provided integrates the Video Content Analysis tool (VCA) and fisheye cameras from 6 MP DS-2CD6362-IV. An infrastructure that allows protecting forensic evidence from external threats, as well as monitoring the department's procedures.

The Greenwood City Police Forensic Laboratory (Colorado) needed a video surveillance solution to protect the different forensic evidence stored there such as firearms, drugs or cash recovered from raids.

The forensic laboratory needed to expand the surveillance coverage of the facilities, incorporate a more sophisticated system to increase the use and intelligence of the closed-circuit television system (CCTV) that they already had. Besides, they wanted to incorporate cameras in the exterior areas where they lacked them.

We wanted to optimize the system we had, which was already obsolete. It only allowed us to make live recordings, it did not detect motion and was only installed in limited areas, where the evidence is located. We wanted to move from this one-dimensional system to one that offered us greater coverage, viewing both the exterior of the building, as well as the interior of our vehicle processing area and test room, comments Joe Gutsgell, commander of the Greenwood Village Police Investigations Unit.

The company Safe Systems was responsible for carrying out this improvement project for the video surveillance system and opted for the technology of Hikvision to carry it out. In this way, the Video Content Analysis tool has been implemented (VCA) in the critical areas of the laboratory and six fisheye cameras have been installed and 6 MP DS-2CD6362-IV to expand coverage and provide detailed images of the areas to be covered.

Fisheye technology is designed to capture images from all corners of a given place and eliminate blind spots. High-resolution images up to 3,072×2,048 at 30 fps permiten que la policía de la ciudad de Greenwood disponga de una visión global en tiempo real. Besides, el infrarrojo proporciona visibilidad a una distancia de hasta 15 metros en condiciones de poca luz o incluso en total oscuridad.

Una de las características más destacables de esta cámara de ojo de pez es su vista panorámica de 180 o 360º, idóneo cuando se necesita una cobertura completa. También dispone de vistas dewarped, que permite reorientar el punto de la lente redondeada de ojo de pez y que hace que el vídeo parezca más realista. Finally, una función suave ePTZ facilita el giro, inclinación o zoom. La cámara de ojo de pez es una solución muy útil y rentable para pequeños espacios de interior, como este, ya que un equipo realiza el trabajo lo que se requiere tres o más cámaras fijas estándar.

“Aprovechamos el ojo de pez de 360° para controlar las imágenes de tres puertas simultáneamente: el exterior, una puerta interior a otra parte de la oficina y la sala de pruebas”, explica Marcos Overland, senior Safety and Life Security Consultant de Safe Systems.

En la habitación donde se almacena las propiedades confiscadas por la policía (weapons, drogas ilegales y dinero en efectivo) se ha instalado la mini cámara domo de 1,3 MP de Hikvision DS-2CD2512F-IS-los. Una segunda cámara minidomo está siendo utilizado en la sala de procesamiento de vehículos, donde se encuentran los coches involucrados en investigaciones.

Dos cámaras de 3 megapixels (DS-2CD2132-I-4MM) vandal-proof IK10 and with IP66 protection, are located outdoors and are responsible for capturing images of people and vehicles entering and leaving the laboratory. 24 hours of the day.

Their infrared offers coverage up to 30 meters and they are equipped to operate at temperatures well below zero to withstand the cold days of the surprisingly cold Colorado winters.. The WDR functionality prevents images from being blurry or turning into dark areas in direct sunlight or high contrast..

The new security infrastructure also includes 16 Hikvision DS-9616NI-ST NVR, a device that offers RAID functionality and support, along with eight SATA interfaces and up to 48 TB de almacenamiento. Some equipment that is responsible for providing remote vision.
