Sony helps a Chinese prison introduce IP video surveillance

En el exterior del centro penitenciario de Yicheng se han sustituido las antiguas cámaras y se han instalado 200 equipos SNC-ER580 y SNC-CH240 de Sony. El objetivo es migrar la solución de seguridad CCTV analógica hacia un sistema de videovigilancia y monitorización digital.

Las limitaciones presupuestarias hace que las prisiones de China tengan instalados sistemas de monitorización y seguridad de baja calidad. Este es el caso de la penitenciaria Yicheng, un centro ubicado en el distrito de Hefei de la provincia de Anhui (República Popular China), que data de 1983 y alberga hasta mil internos.

Este centro disponía de un anticuado sistema de seguridad CCTV analógico que había provocado varios problemas. The cameras installed outdoors suffered the consequences of a low level of environmental protection, which caused dust to enter their body and optics, resulting in blurry images. Extreme temperatures, the rain, snow and fog present additional challenges. The electrical interference affecting the old cameras contributed even more to the poor image quality. This led to costly repairs and some devices were discarded after just one year of use.

Besides, This old system posed a major security challenge. Prisons are inhospitable environments with a low tolerance for surveillance failures. The malfunction of a camera at a monitoring point in the peripheral area became a security problem for the prison administration and the system integrator,, as it was necessary to test,, install, and replace the camera..

Faced with this situation, Yicheng Prison decided to renovate its infrastructure and implement an IP video surveillance solution,, installing cameras with Full HD resolution in Sony all exterior areas of the facilities.. In total, The prison has 25 PTZ cameras SNC-ER580 and 176 SNC-CH240..

The SNC-ER580 camera provides images with Full HD resolution, (1080p) very detailed over a wide viewing area,, with high sensitivity in low-light conditions.. The 20x optical zoom with unlimited rotation of 360 Degrees and high speed of the IP camera help ensure that security personnel do not overlook rapidly developing incidents.

The SNC-CH240 is a fixed IP camera that captures images in Full HD resolution with sharp details. Sony's Exmor CMOS sensor ensures high performance in terms of noise level under low-light conditions.

Both cameras feature advanced analysis functions built into the front end, which depend on the user's needs, such as identifying or recording fights through voice frequencies or defining warning lines, which helps prison staff as it allows for more systematic monitoring and analysis of inmates' movements and behaviors.

The Sony video surveillance solution, thanks to its intelligent monitoring system, has enabled prison staff to identify potentially dangerous situations and respond quickly to them. The stability and reliability of Sony's solution platform allow Yicheng prison to maintain greater security, as high-quality Full HD images are always available.

This migration has been carried out in Yicheng by the company USTC Sinovate Software, w.
