Well I have been working on a CCTV job for a nightclub that is opening up this weekend. The club came with cameras and a XP machine with a DVR card and software installed. I was able to get everything up and running with no issues, and was able to gain access to the cameras from within the internal network. Outside is another story. The main issue is that I cannot even ping the public IP address. It is a Cablevision commercial account with a motorola modem (forgot to check on the model number). Is it possible they block outside access? I don't do a lot of commercial work and this is the first I have tried to gain access to a commercial Optimum modem. Any ideas on what I can do? I am thinking I might have to call Cablevision to have them grant access, but am not sure.

 

Yeah, ports are most likely blocked in the router. Are you trying to remotely control the PC or just view cameras?

 

I forwarded all the necessary ports on the router.

 

The router may be setup to not respond to external ping requests....

 

ok, again, whats the goal, that'll determine the solution.

This is true too.

 

The goal is to access the DVR to view the cameras remotely.

I looked around a little but am not sure where to find any settings that blocks external ping requests. The router is a Linksys/Cisco router, but I have to check on the model number.

 

try opening up other ports temporarily and point it to the PC. for ex. open port 3389 and see if you can RDP into it. does the PC have an internal static IP?

 

Wow, I doing the same thing. Have to finish it this weekend. I'll have to get back to you. So far I am having the same problem. Everything is up & working, but I do not have outside access. I'm not even able to remote desktop to the PC from the outside. The ISP in my case crapcast may be blocking something. I'll have all day Saturday to mess with it.

 

Are you using the cablevision supplied modem with built in router?

I would turn that crap into gateway (passthrough) and just use my own router of preference. You need service admin rights to go inside the real settings of the cablevision modem/router. I've had same issues with comcast, of course I got the user/pass but I ended it up turning it into a passthough modem and using a linksys vpn router.

VPN is usually best option for secure access. This way you only need to connect to the local network, and then you can run off your camera viewing software at local domain 192.xxxx (This is how usually I do secure businesses such as jewelry stores).

What software are you using to view? I'm using EyeCom FreeView Pro.

Also, as I remember, on my camera software I needed to open four ports 1001, 1901, 7070 and 8080.

 

A good website to check if your port is open: http://canyouseeme.org

 

Is there a piece of software you use when trying to connect to the DVR? If so, whats the name of it and does it connect based on IP?

 

The modem is not a combined modem/router. The router connected is a Linksys. The software on the computer is called Digital Witness. I did not install or supply it. I can connect to the DVR through IE based remote software when in the internal network and using the IP address of the computer/DVR. Simply accessing from outside the network is the issue.

 

Linksys router? eeeks.

 

There may be a firewall on the motorola also, I don't' know for sure, I don't mess with a lot of Motorola modems. However, if you give me the model # of the modem I can check. What port #'s have you already forwarded in the linksys?

 

Exactly what I was thinking.

 

lynksis = cisco = headache, but doable.

By the way, this may seem stupid to you, BUT, are you trying to access the html page with cameras feed by pointing to a physical ip address while being on the LAN?

pm me the feed / ip if you dont mind...

(linsys is a dumb dumb, and may prevent you from pinging or connecting to itself from within itself.. from lan to physical)

 

Also, is this a static or dynamic IP that you are accessing? You may need to make use of a service like dyndns.org.

 

Those saying linksys is bad what brand is good?

 

lynksis is not bad when you have good model with updated firmware, they are a headache to setup, but once done, they will last and last. I use commercial cisco instruments, very good stuff...

For home use I only use D-link.. love 'em.

 

Pm'd you
