Signdotcom Sdn Bhd is an established advertising signage company in Malaysia over 38 years. We know the signage for the future is going to be active electronic signage; therefore, we have expended our service into manufacturing LED screen and message display. We have developed using radio wave wireless remote control communicate with LED message board. This is something many people never think of possible. Using radio wave i can easy change wording i want even the screen is high up or far away. How far? If without any signal interruption, radio wave can travel about 3 miles. We have exported this products to Korea and macau. My client who owned the 5 stars shopping mall in Malaysia (pavilion kuala lumpur) is very happy with the LED display technology. We have changed the way people think about GSM LED message display. Before, we have to go through a lot of trouble in setting up the LED display with either the computer or cell phone. No MORE SPENDING TIME ON ALL THAT SETTING. We have designed a easy to use GSM LED message display. All you need to do is place a SIM card into GSM adapter, and you can send messages to your LED message display no matter where you are. In order to enhance the security, we have added PIN to each screen. But of course if you are just looking for LED message display connect to computer to change message, yes we do. If you need anything else feel free to contact us. We will always be there for your need.
