The signals for those guys are not HDMI but SDI. Those that TV stations use are incredibly expensive but guarantee stable 24/7 operations. In the broadcast industry we call what you are looking for a video mixer.
#MIX TWO VIDEO SURVEILLANCE FEEDS INTO ONE WEB MONITOR HOW TO#
If you have any idea on how to accomplish this, please let me know. I could not find a video capture card for computer with multiple inputs that I could use to merge the images either. The video capture device I could find only have one input and one output to record then display the image (these are generally game streaming devices) and wouldn't allow me to merge the images in real time. I checked the available devices and none of them seem to be able to do this.Īnother solution would be to have a separate computer, able to capture video input from the outputs of the main computer, does the merging operation and send the image to the screen for display. if there is a red pixel 0xFF0000 on output 1 and a green pixel 0x00FF00 at the same position on output 2, the pixel becomes yellow 0xFFFF00), or any other method. output 1 write its image and the output 2 overwrite non transparent pixels), less ideally by addition (e.g.
It could work in different ways, for example with a system of priority (e.g. In case that isn't clear, here is a simple schema: 2 HDMIs) or different, anything that works would do. The outputs can be of the same type (e.g. A device that would allow to merge the image coming from 2 outputs (HDMI, DVI, VGA or any other type of image output) into one final image displayed onscreen.
