G&G Bank/finance IP surveillance solution applies the wide range of cross-domain networking. The fluent transmission of single or multiple video could be guaranteed even under the limited bandwidth. And it is realized by main lines management, network auto-adaptability and transparent channel. Aiming at the wide dynamic range of illumination and low illumination of bank hall, G&G provides selected net- work cameras with corresponding functions. Furthermore, images from multiple cameras could be jointed to- gether as a whole image. Hence concern persons could watch a more direct and complete image. Combined with the fact that storage duration is 90 to 180 days, G&G surveillance devices could save storage space and reduce customers’ cost through VBR, automatic frame reducing and B-Frame. Besides, G&G IMOS platform could not only be associated and integrated with many subsystems such as alarm system and access control system, but also manage resources to enhance the security management of banks and financial institutions.
