Good day, may be some one can help to us in next situation. We have object where installed Dahua HD-CVI DVR 7108 h-v2 and software for pharmacy storage (VMS). We has realized POS data overlay from VMS to this DVR after read this manual: http://dahuasecurity.com.ua/upload/file/ATM%20POS%20Function%20Introduction.pdf Everithing work well, BUT this is system based on CVI cameras, and we need use IP cameras, and want to use ILDVR Hybrid Server software. We find next manual: http://amax-sb.ru/_fr/2/P.O.S-ATM_machi.pdf , but have little problem, we cant set IP adress and port where will sending data for overlay and we just dont know which format of TCP packet accept this software. For example we try to send same TCP packet like Dahua version, but nothing happened Now factory explayne to us that his NVR support only POS devices, BUT any way POS device send SAME tcp packets, and after analizyng them NVR made overlay to video... Have any ideas? Best regards.
