Viewing Dvr remotely error

[balmed out 0]

Hi Im trying to get my edr1600 to work remotely. I did everything like in rory's sticky already but im having a problem. I get to the stage where i can log into the cctv system but then as its opening the java application i get the following error message.

I have the cctv system runing from 192.168.1.100 with the router port forwarding to it on port 80. I can get past the router log in and the cctvs own log in from both the internet using the static ip and my own network using 192.168.1.100. It then starts loading the java applet and just as i would expect the camera display to appear i get the error whether accesing from the net or my own network. The cctv system, when i try to upgrade software responds that theres nothing newer available. If i set the cctv sysem to 192.168.1.254 then it all works perfectly but obviosly only from my own network.

 

Thanks for taking the time to read and any help would be great.

Well, the errors point to a problem with the Java runtime, if not the applet itself... but the fact that it works with the DVR set to a .254 address is odd. Since that does work though, can you not just forward the necessary port(s) to that address and be done with it?

 

Short of that, you could see if there's an update for your Java runtime, or simply uninstall and reinstall Java.

As Soundy mentioned its strange it works on 254 and not the other, but as it DOES work on that, then just leave it set to that, or anything from 200-254, then port forward to that IP.

 

Also what OS are you using to connect to this?

thanks for the help but im afraid if i use the 192.168.1.254 while it works fine on my own network i cant port forward to use it with the static ip also when i tried last it made my internet connection stop working though i dont remember tat happening before. i tried .200 but i had the same problem. I presume it couldnt be a problem with speed or bandwidth? its really getting to me at this stage.

so, remote access works in LAN(192.168.x.x) and failed when accessing from internet(x.x.x.x)?

you might wanna try disabling IE's security protection and see how it goes.

im using windows 7.

 

No its not working on the local. My gateway ip is 192.168.1.254 it will only work when set to that address over the network. but then internet wont work as sharing ip and even if it did i wouldnt be able to configure router.

Having tried everything im havig no luck. Still confused as to why it work on routers ip originally and as to why always works with the html login par but not the java part. Is it possible that after doing it once the originall addresses used are somehow programmed into the java section of the cctvs code. Is it safe then to use the factory reset function or could that screw up the cameras etc? theres an option of backing the old ones up to a floppy but when i try this it doesnt back them up and the system reboots for some strange reason.

cheers for all help
