More than 3,000 of Rainbow's 1/3" WDR cameras have been used by HSBC at branches in Mexico city.
These are units whose firmware suits lighting conditions created by the client's glass-clad buildings. The cameras are modified versions of Rainbow's models which capture highlight and shadow detail in the same scene while also offering true day and night images through use of a moving filter.
The bank is benefiting from 540 TVL and an ability to obtain footage at minimum illumination of 0.6 lux. These cameras have an on-screen display and the generic equivalent models in Rainbow's standard range are supplied with a three-year warranty.
While glass coverage has “green” benefits in terms of heating and lighting, it can be problematic for suppliers of surveillance products. Traditionally, cameras suffer from lack of detail in high-contrast and back-lit situations, low clarity when shadow is predominant and image washout from glare reflection which is a problem in banks if the teller is separated from customers by a glass partition.
HSBC is enjoying superior color rendering and optimal exposure across a wide range of lighting situations including lobbies, main vault areas and within treasury office spaces.
The engineering values in these units reduce pixel blooming, vertical smearing and camera blindness, factors often known as noise. The choice of camera was made by local integrators TECSIS who drew on extensive experience to conduct site surveys. Evaluation was made of the client's precise requirements, and the optical performance of many camera types was compared under these unusual conditions. TECSIS have worked closely with the client to enable bank staff to identify clear-cut incidents as well as observing unusual patterns of behavior.
HSBC are recording the footage provided by the Rainbow WDR cameras to stand-alone DVR units from March Networks.
HSBC's Mexico headquarters are in an affluent area of downtown Mexico city adjacent to The Angel of Independence. About 2,800 people work at this 12,000-square-foot tower, which has 36 stories and cost US$150 million.
