PTZ control

[myplace46 0]

Hey guys,

How does one manage RS485 control of cams if the DVR card doesn't have RS485 connections?

The card I'm looking at is a hybrid but, only has PTZ control for IP cams.

Thanks,

John

i would say you would need a seperate joystick controller

Have you looked into an RS485 to USB converter

 

Also this may help you

Thanks for the link, Jason.

Looks like the way to go.

If your computer has a serial port, you should be able to use that:

Hey Matt,

Yeah, I went and ordered a 232 to 485 converter.

Then I realized I don't have a 232 port on my computer! my MB is so "advanced" it only has USB, SATA and firewire I/O ports.

And of course, PCIe expansion slots so I can't use my old PCI cards either. I just ordered a USB to rs232 converter.
