Transmission Switch

WHY DAHUA SWITCH ?

Non-Blocking Video Transmission Considering the high data rate and jumbo frame (I frame), Dahua switches adopt a larger buffer memory compared to normal switches improving parallel transmission for large frames. Moreover, Flow Control is another feature which is able to smooth the video transmission. Wide Working Temperature Design The temperature of tradional enterprise switches ranges from 0 to 40°C. If temperatures are out of range, some devices may malfuncon or operate less efficiently. The Dahua switch can funcon normally in a wide range of extreme temperatures from -40 to 75°C.

Normal Switch

Frame 0.25-0.5Mbit buffer memory Not able to handle too many parallel data frames so that causes video lag.

1-4Mbit buffer memory Powerful enough for parallel transmission of video stream. Frame
