Question Access to IP Cameras from 2 separate networks?

[wex56]

Hi,

I have 2 separate networks ( 2 houses side by side) that have ethernet cable ran underground connecting them. Each of the houses has its own internet connection. All IP Cameras are connected to one house. Is there any way I can use existing ethernet cable to have access to IP Cameras on both networks?

Thanks

Going to be messy without a actual router....those device you buy in consumer electronic store are not routers.

The largest issue is you have 2 different internet connect and each of those "routers" are giving out ip addresses via dhcp.

If you just simply connect the networks together then you are going to get devices assigned to the different internet routers kinda randomly. In addition unless you different subnets the 2 routers will have the same ip address. Just changing the subnet only fixes that problem it does not fix the DHCP issue.
Now you could assign everything static IP addresses and different gateway IP so you could control exactly where things go.
It works but is a pain to maintain.

What you really need is a actual router between the 2 networks that allow traffic to go between them but keep the DHCP broadcast message on their own local lan.

What do you mean by actual router? Could you give more info or some links.

I know that connecting ethernet to both routers would be a mess and its even a question if it would work.

Thanks

The devices you currently have are best called gateways. They take a single lan subnet and NAT it to a single wan IP address.

A "router" can actually send traffic between different subnets.....ie route.
You can use a dual nic pc to do it with a linux OS. There are also a number of fairly inexpensive boxes that can function as a router. This is one example. Note it looks like a simple switch but it is a massively complex box to configure. It supports many complex function that only a ISP would use. It also does the simple stuff but the learning curve is huge.
