With the increasing requirements of users on the quality of surveillance video, the application of high-definition video in security monitoring has become more and more popular, resulting in a dramatic increase in storage space and costs. Compared with the H.264 encoding technology currently in use, H.265's high compression rate feature can save about half of the storage space, thereby significantly reducing the video storage costs. Compared with H.264, H.265's greatest ability is to reduce the data transmission bandwidth to half that of H.264 on the premise of maintaining the same image quality. At the same time, it also supports a resolution of up to 7680×4320, so even 2160P or even higher levels of Ultra HD video can be encoded in the H.265 format.
With the development of semiconductor technology and after solving the bottleneck of H.265 computational complexity, H.265 is bound to replace the current H.264 in terms of UHD surveillance applications, just like MPEG-2 before H.264 replacement. technology.
Overhead Sectional Door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
