Thanks scorpion, i think this might work, but im not that good on circuit, though i cracked few on my college years. i might need some few refresh on it. yeah thats true this is a low cost setup. i will post again hopefully if i make the circuit.

THANKS scorpion, yes im using two stations. what im trying to do is: 1.controller 1 and controller 2 can control all ptz cameras. 2.controller 1 and controller 2 should not have interference. 3.controller 1 and controller 2 will not control one camera at a time "no worries, i told operators to do so". yes avp101 have a dvr input which can control the dvr, but unfortunately the that dvr input(rj11-rs232 on dvr side) sends the same protocol and baud rate as it sends on its ptz port, meaning its dvr and ptz port throws the same data. but i haven't tried the 1 controller directly to dvr. hope it will works, thanks for the suggestion. multiplex system i think wont help it. because my requirement was to control all ptz with both controllers.

Anyone? has an idea how to integrate or parallel connect two(2) avp101 to control lots of cameras, without jamming signal when using both ptz controller, i just simple parallel connect their wires, etc.... i came about jamming the signal passing through the ptz cameras, both controller broadcasting same signal when using both, so when running two diffrent cameras with both controller their going nuts. anyone has an idea?? avp101 doesnt seems to have a slave and master capability.
