How To: Set Up Multi-Camera IP Routing#

Before you think about the correct IP configuration of your system and cameras, you should think about the architecture you target. You can do one of the following:

  • Work with a single network and share the available bandwidth between the devices
  • Set up multiple networks to use the full bandwidth for every single camera

Both architectures are detailed below. There are also mixed scenarios possible, but those won't be discussed here.

First, choose the size (amount of devices) of your network. For Machine Vision applications, Basler recommends using an IP address from within the reserved private IPv4 network ranges:

IPv4 Network Ranges

In the following, we will focus on a class C network, as this is most common. To further simplify things, we will always use the subnet mask, allowing 65000+ subnets with 65000+ devices each.

An IPv4-Address consists of 4 decimal blocks separated by dots. With the given subnet mask, the first three blocks indicate the subnet (Net ID) and only the last block allows numbering individual devices (Host ID).

Net ID and Host ID


In every network, the first and last IP addresses are reserved and must not be used for your devices. In the example above, that is and

Shared Bandwidth - Single NIC#

If you can afford to share the GigE bandwidth for multiple cameras, a single network and Network Interface Controller (NIC) is required. Both the camera and the NIC will have to be in the same network. When setting up the IP address, this has to be taken care of.

The following example uses one subnet

The four IP addresses are based on the Net ID 192.168.1 with .1, .2, .3, .4 as the host IDs:

Shared Bandwidth Single NIC

All devices must belong to the same subnet in order to communicate.


As shown, an additional switch is required to connect the individual components.

Full Bandwidth - Multiple NICs#

If you need the full GigE bandwidth for each camera, you'll have to use multiple NICs and different IP subnets. In the following case, we use two subnets and The corresponding IP addresses are

  • Net ID: 192.168.1 with .1 and .2 as host IDs
  • Net ID: 192.168.4 with .1 and .2 as host IDs

Full Bandwidth Multiple NICs

IP routing: Each camera and NIC has its own subnet
