The monitoring console is the core device in the monitoring system. From here, all the devices in the system are issued and controlled. The high-quality monitoring console can make the monitoring work easier and more efficient. The following small series will talk about how to purchase the monitoring console.
The monitoring console is divided into the main console and the sub-console. How do we choose to buy them separately? 
First, the main console (total console)
The console itself is a combination of various specific devices, including video distribution amplifiers, video switchers (or picture splitters), control keyboards, video recorders (or long-delay video recorders), and power supplies (powering devices such as cameras). Dedicated power supply and so on. Some consoles are currently produced, and some use a multimedia computer as the main control device of the console.
Since the main console is a combination of multiple devices, and this combination is set according to the functional requirements of the system, the main console has similar functions in general, but the details are quite different. Therefore, when selecting a combination of consoles, it is important to understand the requirements of the system before ordering. If you consider that the system is likely to expand in the future, you should have a spare input port or space for expansion when considering the combination of the console (there is a need to expand the device when there is an extension in the console cabinet). space).
When purchasing a monitoring console, the main principles to follow are:
1. According to the number of cameras in the system, select the maximum number of input channels of the video switcher (or screen splitter). The maximum number of input channels should be larger than the number of cameras, so as to leave room for future expansion.
2. Select the number of recorders based on the risk level of the area protected by the system and the number of key locations in the area. In the case of 24-hour recording, the "Long Delay Recorder" should be selected.
3. When the number of cameras in the whole system is large, consider using a matrix control system.
4. According to the requirements of system control, consider whether to set up a sub-console outside the main console.
5. Consider the power supply settings according to the requirements of the entire system power supply.
6. When the system has multiple long-distance signal transmission, it should also consider whether a demodulation device should be added in the console according to the way of long-distance signal transmission (video transmission, optical fiber transmission, radio frequency transmission, video balanced transmission, etc.). (corresponding to optical fiber transmission or radio frequency transmission), compensation device (corresponding to video transmission), restoration device (corresponding to balanced video transmission), and remote handover control device (corresponding to remote switching mode of video transmission) and the like.
The consoles combined according to the above basic principles can generally meet the system requirements.
Second, the secondary console
The secondary console is actually an operating keyboard. On this keyboard, it has exactly the same functionality as the operating keyboard on the main console. Therefore, the entire system can be controlled and operated by the sub-console (operating keyboard). In the working room of the sub-console, there is generally only one monitor, and this monitor can be used to switch the monitoring screen returned by each camera.
The setting of the sub-console is generally used to set one or several monitoring points in addition to the monitoring center where the main console is located. The connection between the sub-console and the main console is generally in the form of a bus, and the connection is very convenient. At the same time, priority control can also be set between each sub-console and the main console. For example, if a sub-console has the first priority control, when the sub-console operates and controls the system, the main console and other sub-consoles have no control and operation capabilities on the system. .
The above is how to purchase the contents of the monitoring console. If you want to buy a satisfactory monitoring console, it is best to ask a professional to guide, so that you can rest assured.
