1. Control system cost: the display sending card and receiving card fees Guangzhou led unit board, are generally used Shenzhen Linsn synchronous control system. The main display area size is determined according to the number of cards led indoor unit board, in general, the larger the area, the higher the density of the number of receivers used by the card, the more led unit board, our company accounted for separately. 2. The cost of equipment: computers, air conditioners, audio amplifier, power distribution equipment, multi-function control card, surge arresters, and LED video processor, site wiring. (Of course, some of the equipment which the user can also bring their own good, of course, less than the device may not be equipped, our company will recommend reasonable configuration.) LED display used in video surveillance and video presentations, the main impetus from two points: first, with the rapid advances in LED display technology, the dot pitch LED rental display more and more small, high-density LED rental display in a limited area with greater resolution , display more clear and delicate. When displaying standard definition images, the resolution has been able to fully meet the requirements. The second is the price factor, once unattainable high density LED die, worth more close to the people. The price per square meter of display area and DLP and LCD products compared to competitive advantages are becoming apparent. It has a very strong competitive potential in surveillance.
