CVA23 0 Posted May 10, 2011 Hello everybody. I have experience installing IP cameras but recently I had to install several converters to allow some analogue cameras (I never worked with this kind) to be part of my customer's network. Everything was OK but some of these cameras are PTZ domes and I also have to integrate this function. The converters have serial ports to be selected as RS485 or RS232, and at the back of the video multiplexer there's a connector called "SDA". According to the user's guide, these are the Biphase outputs. Are these cables which I have to connect to the converters' serial ports? Are the Biphase outputs controlling the PTZ? Which if not? Thank you all. Share this post Link to post Share on other sites
SDM Group 0 Posted May 10, 2011 Biphase is a Bosch/Philips proprietary communication protocol. You may need a Biphase to RS485 Converter. Alternatively, although I don't know your set up, you could leave the PTZ control just the way it is otherwise you may be converting an analogue signal to digital and then back to analogue to no benefit and extra expense. Please give more information if you need further assistance Share this post Link to post Share on other sites
CVA23 0 Posted May 16, 2011 Thank you for your answer, SDM Group. Then I guess the Biphase outputs are the PTZ controls, is it right? Dome cameras and Video Multiplexer are Philips branded. The VM is one LTC 2600 Series. Moreover, the converter supports several PTZ drivers. Here is the list: DynaDome/SmartDOME Ernitec Lilin PIH-7x00 Pelco D Control Samsing/SmartDOME Sony VISCA Canon VCC1 Canon VCC3 Canon VCC4 Will the Philips cameras support some of these ones too?
