What kind of display screen Wuxi Security Monitoring Will choose
Security monitoring It is widely used in modern life and work, such as emergency headquarters, schools, hospitals, banks, enterprises and other places will set up a monitoring room, and the indoor display terminal needs a display screen to display the images recorded by the camera in real time. Due to the large number of monitoring points placed in this type of monitoring room, the images of each point need to be displayed on the display screen separately, and it also needs to be powered on continuously all day, so professional display screen products need to be used. What kind of display screen should be used for security monitoring?
1. LCD splicing screen
LCD splicing screen is the most widely used display screen in monitoring display at present. It is the same industrial panel as LCD monitor, but it has splicing function and narrow frame, so it can be used for multi screen splicing, that is, it can achieve single screen segmentation and cross screen display, with strong functions. At present, LCD splicing screens on the market are mainly composed of Samsung and LG panels, which are stable and can be used 24 hours after startup. If we have hundreds of video surveillance channels, they can be displayed on the LCD splicing screen at the same time to form a large monitoring screen. The screen size mainly includes 46, 49 and 55, and the seam size includes 3.5mm, 1.8mm, 1.7mm and 0.88mm. The smaller the seam size, the better the display effect. The LCD splicing screen is often used in monitoring centers, emergency command centers, large enterprises, hospitals, troops, energy production and other fields.
2. DLP large screen
DLP large screen is also a device used for monitoring display. It is different from the first two display products. It uses rear projection display technology and emits light through optical mechanism. Its feature is that the size of a single screen is large, usually between 50 and 100 inches, the seam is very small, and the two sides are only 0.2mm, so its splicing display effect is good, but its cost is very expensive. An ordinary screen can reach tens of thousands of yuan, and the brightness is low, so installation and after-sales are very troublesome, so its market application range is not large. With the introduction of ultra narrow seam of LCD splicing screen, the market of DLP large screen has been severely compressed. Generally, DLP large screen will not be selected, but only used in a few high-end markets.
3. LCD monitor
LCD monitor is a commonly used monitoring display screen, which is mainly used in occasions where the number of monitoring points is small. Its characteristics are economical and practical; Its panel is an industrial level panel, which supports the continuous startup requirements; There are many screen sizes, ranging from 22 to 100 inches in large and small sizes. However, its frame is wide, and it does not have the splicing function, so it can only display the monitoring image in a single screen, rather than cross screen splicing. Generally, LCD monitors are used for about 10 monitoring points, such as kindergartens, residential areas, banks, etc.
