Kingwood 0 Posted February 27, 2008 If the PTZ dome can controlled by Special Keyboard,I think it's not a good dome,in normal,all PTZ dome must support standard Pelco_P and Pelco_D protocol. Share this post Link to post Share on other sites
rory 0 Posted February 27, 2008 Kingwood, many of the best PTZ brands such as GE etc have their own protocols and require their own specific keyboards to work with them. Optionally one can however generally buy an adapter from them to use other controllers. I cannot speak for this VCL dome though as I know nothing of it.

ronbo 0 Posted February 28, 2008 ya this dome does support the pelco D and P and VCL protocal and also two more, but is there a way i can use my PC DVR card (which i can select which protocal) to function with my PTZ dome as Honeywell told me that it can only be used with the keyboard and by doing that it defets the whole object which im trying to do. any ideas or are Honeywell right and i need a keyboard?? ron Share this post Link to post Share on other sites
ronbo 0 Posted February 28, 2008 But the fact that the unit only used up the coax means that the PC DVR card wont work? Share this post Link to post Share on other sites
Smit9352 0 Posted February 28, 2008 But the fact that the unit only used up the coax means that the PC DVR card wont work? Am I reading this correctly? He's stating that he does not have a RS-485 +/- , that the Protocol for the P/T/Z functions are ran through the Coax? IF I'm reading this right then you will need to find an adapter that will break off the P/T/Z signal out of the Coax line and have into a 2-wire type interface. Unless you can find a dvr (possibly pc based) that can control that type of data through the coax line. Goodluck tho, John Share this post Link to post Share on other sites
ronbo 0 Posted February 28, 2008 Yes but the PTZ does have the data +/- and i was trying to control the PTZ though that but after all my efforts ive found that this dome only uses 'up the coax' so and adaptor that takes the signal from the re232 through to the coax would solve the problem... Question is , does such an adaptor avalible? Share this post Link to post Share on other sites
ronbo 0 Posted February 28, 2008 ive tryed finding a DVR PC card that dcan use 'up the coax' but so far ive dran a blank as this method of controling PTZ seems to be old tech Share this post Link to post Share on other sites
