The technical indicators of the quality of the LCD splicing screen are related to the quality and technical indicators of the entire security system, so the selection of the LCD splicing screen is very heavy. Many customers choose low prices, so there is no quality guarantee, LCD splicing screen is a system, not a display.
The principles of choosing LCD splicing screen are as follows:
(1) Be sure to select products that have passed the certification of the national statutory quality supervision and inspection department and relevant management departments and are allowed to be produced and sold. Their product quality and technology should meet the requirements of relevant national regulations and standards.
(2) The actual technical indicators of the LCD splicing screen should be consistent with the product specifications given, and the technical specifications given in the manual should be more detailed and specific.
(3) The technical indicators of the selected LCD splicing screen should generally be higher than the technical indicators of the entire system.
(4) For the size requirements of the LCD splicing screen, the choice is: of course, the larger the size, the better. Now the stitching gap of the 55-inch LCD splicing screen is 5.3mm, because the larger the stitching gap is, the smaller the viewing angle effect will be. The better. According to funding requirements, you can choose 46-inch LCD splicing screen, the price is relatively cheaper.
(5) When choosing the LCD splicing screen, it is best to have a fan, the LCD liquid crystal screen has a higher heat generation, and the LED liquid crystal splicing screen generates less heat.
(6) It is best to choose a liquid crystal splicing screen with a metal shell. Such a liquid crystal splicing screen has better shielding performance, (especially after its shell is grounded) and is not susceptible to interference from space magnetic fields.
(7) The position of the LCD splicing screen equipment should be such that the screen is not subject to strong external light. When unavoidable strong light is incident, corresponding light-shielding measures should be taken.
(8) Quantity: The number of LCD splicing screens can be determined according to the number of cameras on site. Generally, 4: 1 is used. If there is limited space, you can configure several small-size LCD monitors on two LCD splicing screens.
(9) Sharpness: According to the resolution index of the camera used, the LCD splicing screen with a higher definition should be selected. The brightness of the current LCD splicing screen is relatively good, 450cd / 700cd.
(10) The setting of the LCD splicing screen should be considered in accordance with the design of the monitoring center, with a reasonable layout, easy operation, and easy maintenance.
No matter which brand of LCD splicing screen is used, its safety is crucial. Various safety performances must be guaranteed for the relevant standards of LCD splicing screens.
