Vi-video inter-phone has a literature name-Building Speaking System. It is different form the two way radio. Vi-video inter-phone is a machine that can talk to others through video but the two way radio can not do that. But we usually install the machine on our house or office to see someone out the door.
Flying has made PCB on two way radio for several years. With rich experience on the foundation, we explore to break through the hardship and make the PCB circuit close to flawless. Many people think that Flying just does things as customers demand. But in fact, Flying always spend lots of time to revise the imperfections of the PCB design with extreme carefulness from customers. And our customers are glad and enjoy the service we have offered. We do things for only once and make it at the first time.
Here is a sentence from one of our customers: our products can make our customers see what happens inside their homes when they are outdoors and make people inside their homes communicate with people outside the door conveniently. Flying PCB meet all our needs of our product and we will keep a long trading relationship with Flying.
