I went to see a customer this morning who has 2 x ultra 8 PTZ'S.
His current system is quite basic 16ch avtech DVR and 10 fixed cameras, he would like the 2 x PTZ'S installing.
I am not familar with american dynamics domes as most of the stuff i come accross is DM, pelco and samsung all use either RS485 or up the coax data.
From what i found on the internet the AD domes uses sensormatic, pelco etc all RS422 and coaxitron.
From what i cab gather the only difference between 485 and 422 is 485 is 1 way and 422 is 2 way, i did wire a 485 controller and change a few setting but it did not work.
So my question is is it better to get a dedicated controller for the domes or what type of convertor is best?
Is anyone familar with the address and protocol setup of these domes just so i know if i am doing correctly.
Thanks
Alan
