The Dahua DHI-M70-4U-E is the 4U chassis at the centre of Dahua's M70 video wall system. It takes pluggable cards for decoding, video input and video output, and uses them to put camera streams and other video sources onto a wall of screens. It is aimed at control rooms, monitoring centres and large sites where operators need many cameras visible at once.
The chassis has 12 slots: 2 for main control boards and 10 for video and audio function boards. Fully configured, Dahua rates it at 80 channels of 8MP decoding or 320 channels at 1080P, and it can splice output across up to 60 LCD screens, with zoom, merge, roam and overlay of windows on the wall.
Six gigabit RJ-45 ports handle matrix control, preview and central storage, and the system can be run from a web browser, the local GUI, a video platform, a network keyboard or an iPad. Dahua's ordering information lists the chassis on its own, so decoding and output cards are chosen separately to suit the size of the wall.
