On DVR what does this port allow you to do?

[supertech 0]

My DVR has a rs232 port and the spec says "RS-232 connector (ISP. For RD control)". What is that used for? I am looking for a way to connect a pc as a controller for the PTZ cameras. I want to use remote access to a pc next to the dvr for veiwing and controlling the cameras and backing up the recordings when the dvr is full. Have been looking for a pc application for controlling the ptzs but have not had any luck with that.

SO how do I get the video to work along with the DVR unit?

You haven't told us what brand / model the dvr is... you may or may not be able to do what you want depending on the model / brand.

 

RS232 can be used for many things (model depending) including:-

*Control PTZ cameras

*Mimic front panel buttons via PC

*Update firmware

*Use for system integration / POS integration

*Upload programming / settings

*Enter self test and similar manufacturer back end systems

*Connect a PPP modem

*Connect a GPRS / 3G modem

 

I have never in my life seen an RS232 port used for video footage backup though.

 

Also Scorpion has linked you to a site has software that allows you to control PTZ cameras (supporting Pelco-D / P) directly from your PC.

Here is a more direct link to the software / section of the site that states you can control Pelco-D/P cameras...

Wait a minute!

 

If I left some information that has some value then it was posted by accident!
