Video switcher
- Apr 13, 2018 -

Multiple video signals need to be sent to the same place for monitoring. Each video can be assigned to a monitor. However, the monitor occupies a large area and the price is expensive. If you do not require constant monitoring at any time, you can add a switcher to the surveillance room. The output signal is connected to the input of the switch. The output of the switch is connected to the monitor. The input of the switch is divided into 2, 4, 6, 8, 12, and 16, and the output is divided into single and dual channels. You can also switch audio simultaneously (depending on the model). The switcher has manual switching and automatic switching. The manual method is to see which way to switch the switch; the automatic method is to make the preset video delay switch in order, and the switch time can be adjusted by a knob. Usually between 1 second and 35 seconds. The switcher is cheap (usually only three or five hundred dollars), the connection is simple, and the operation is convenient, but only one of the images in the input can be seen in one time period. To view multiple camera images on a monitor at the same time, you need to use a picture splitter.
