[Gordy 0]

Thank you for having this forum open to discus issues about cctv .

My problem is I have a new roter modem set up the problem is I cant not use the PTZ cameras via internet, I can on the lan . I was not having no problem before I think there is a port that I forgot to open can anyone tell me what port # is for the PTZ controls. Thanks You . Mr Gordy

Need a little more info before anyone can even think about answering this...

 

What make/model of PTZ?

What make/model of DVR (if any)?

How was it connected before - modem, router, etc.?

What remote software or viewing method (browser) are you using?

Hi Soundy

I have a geovision 800 16 channels , my PTZ cameras pelcos , and my router modem is 2 wire , I have a Geo RS-485 for the PTZ . I was not having any problems before so I know everything is ok accept my port that is not open to have my PTZ work . Thanks

I forgot Im using a internet Explorer .

Router ports should have nothing to do with it. The GV software communicates directly with the PTZ via the RS-485 port, the signal doesn't go through the router. The web client (via IE) allows you to control the software. If you can access the software remotely, your ports should be fine.

 

Only thing I can think of is if the remote client sends camera control on a different port, as I know some remote clients do... but I wouldn't think that would be the case with the web-based client.

 

In any case, you can test it by finding the "DMZ" section of your router, and setting your DVR's IP as the DMZ... that will forward ALL otherwise-unassigned ports to the DVR.

You might have to call tech support. I had to do this with Dedicated Micros, at which point I learned that the images go over port 80... but the PTZ controls go over port 1025 via UDP.

 

In other words, you may have to forward another port.

So funny you say that about DMZ, I got so fed up so I click on the DMZ box and everything works fine .

Good stuff, but you might not want to leave it that way - that essentially leaves that machine wide-open to the internet, and with a PC-based DVR (particularly a Windows-based DVR), that means it becomes a LOT more hackable.

Thank you so much for everything Im going to do a little more research and see what port PTZ uses , I think Sawbones you are right is another port but God knows what the number is Im going to try 1025 and see.

Soundy thanks for everything and have a great Xmas to all. Mr Gordy

Try opening a DOS window on a remote PC connected to your DVR (Windows popup key,run, type in "cmd" in the box, on a Windows machine.)

 

In the window, type "netstat -a" (without the quotes) This will show all active ports, look for ones that say "established" with the remote IP listed.

 

This is a method I use for less-than-well documented pieces of equipment of many types to learn what ports are being used.

Thank you so much Hardwired for the great information I'm going to try that.
