We are a small CCTV manufacture in Taiwan, selling our product in US and also Asia. We notice that almost all the manufactures have Pelco protocol built in their keyboards and PTZs so that the keyboards or PTZ can control or be controlled by the other brand’s devices. We would like to know that if Pelco D or Pelco P is an open source that all the manufactures are free to use? Or do we need a license agreement?
