hooking up 2 dvrs from the same site for remote access

[blowrabbit 0]

has anyone hooked up 2 dvrs at one site to be accessed remotely? do you just use a multiport 10/100 switch ? I was told you need to configure the modum so that it has 2 listening ports, say 1025 and 1024?

 

oh yea the two dvrs use different software for remote access and different compression but that should not matter? any thoughts?

if the DVRs allow the ports to be changed in the DVR software, then it will work fine, change them then port forward those ports in the router to the DVR's assigned internal IPs.

 

What DVRs are they?

They are both ge, one is a symdec vsr-4-300 and the other is a dvrme 16CT-640-A. So one is wavelet and one is MPEG4. The Symdec is not supposed to supprt multiplexing but i did run a 4 channel mux through one of the 4 channels and it worked fine along with the other 3 channels. This is to get around the only 4 channel restriction.

 

do you mean to have both dvrs assigned to the same ip address?

You got most of it right in your question already. Please make sure which port each DVR uses to connect to the internet. Most of the DVRs use some specific ports that you can find in their manuals. For our ICrealtime machines we use 9080. If you want two DVRs for one IP, you need set different ports, in other words, DVRs can not share the same port while they can share the same IP. Each DVR has its unique internal IP address, the modem/router is the device that has the external IP. You need to config the modem/router so that it forwards the ip data from the internet to the particular DVR IP. Say one of your DVR is 192.168.1.100 working on port 1024, the other 192.168.1.110 on port 1025. In the router, you need forward all traffic from internet for port 1024 to 192.168.1.100, traffic for port 1025 to 192.168.1.110. This is normally called "port forwarding" or "ip pinhole", in the router.

Each DVR has its own IP address (internal ip, that is). the router or modem has the external IP. All internet traffic goes to the router/modem first, then the router uses the port to decide where it will forward the data to.

what they said above, different internal IP addresses, different internal ports, one single external IP address, port forward in the router to those internal IPs based on the incoming port numbers..
