When you go to China and other electronic markets to ask for monitoring products, many businesses will set up several prototypes, and the images you see are displayed through display devices. Note that the author's use is to display devices instead of monitors. In the industry, strictly speaking, the display device should be a monitor, but it is not surprising that the monitor acts as a monitor for consideration in the consumer market.
The monitor is confused with the display application. The BNC interface tells the truth.
I wrote an article before. DIY In the article of family monitoring system, some netizens think that the display device part has not done a detailed introduction. Today, we set up a column for the problem of display device to tell you how the monitor acts as monitor when DIY family monitors.
We still take the simulation monitoring system as an example, the front-end monitoring under multi-point control. Video camera The analog device is equipped with the backend DVR for record storage. Whether the monitor can be used as a monitor depends on whether the VGA interface on the DVR is powerful. For most of the DVR that I contacted and tested, Hard disk The video recorder supports VGA interface, even for those who are in touch with the monitor for the first time. Computer The pin of the display can be butted with DVR.
Comparison between VGA joint and NBC joint
Obviously, a simple connection can turn monitors into monitors, and it's really a bit of a "second second grid" posture. Display connection below Power Supply Then connect the camera to DVR with the BNC connector. Here, I tell some beginners the way to connect the interface. In brief, the surveillance camera must correspond to the video input interface. The serial number of the interface in 4 way DVR is entirely in accordance with personal preferences.
See for yourself. Digital Video Recorder There is also the video output port of BNC interface. This topic will return to our understanding of display devices. Let's talk about it. Let's talk about the display device on the BNC interface.
No matter in terms of concept or application, any monitor has BNC interface. This is the most popular explanation given by a security engineer in the industry. For a long time, the best way to distinguish the two is BNC interface.
Interface between VGA and BNC on DVR hard disk recorder
In the interface between DVR and monitor, we can easily find the BNC interface. Compared with the traditional video interface, it has a very tight connection, so there is no need to worry about loose interface and poor contact. When connecting, the BNC connector has a slot, aligning the video line and inserting the interface into the slot. In addition, the BNC connector can reduce mutual interference between video signals and achieve the best signal response effect.
BNC is mostly used for security industry monitors to transmit video signals and cable TV indoor wall interfaces. From the application area, BNC has unique status in the field of video surveillance. For consumer monitoring and display, is it worthwhile to purchase professional monitors? Let's look down.
We compare the same brand of monitors and monitors, we can not see the difference in terms of the following parameters, but from the price point of view, the difference between the two is 1000 yuan. Of course, the monitor has longer life span than the monitor, and it is more flexible to withstand high temperatures or harsh environments.
The difference between monitors and monitors
Today, I introduce the difference between monitors and monitors from the aspect of BNC interface. At the same time, I also let people who first enter the field of security to connect DVR with display VGA interface. In subsequent columns, the author will also introduce relevant contents around family security or DIY.
