I'm trying to configure a zoneminder video server that connects to IP cameras on the LAN but I would like the cameras to be on a different subnet to our office and I'm not sure how to accomplish that via static routes.

It seems that most other about this topic questions are based on having two subnets that each have a router with a gateway. What I'm trying to do is have eth0 connect to 192.168.1.0 and have the cameras be in 192.168.2.0 but be accessible by the server without needing any additional network devices.

Any ideas?

Try changing /etc/network/interfaces to 

auto eth0
iface eth0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    network 192.168.1.0
    broadcast 192.168.1.255
    gateway 192.168.1.1
    dns-nameservers 192.168.1.1

auto eth0:1
iface eth0 inet static
    address 192.168.2.10
    netmask 255.255.255.0
    broadcast 192.168.2.255

Restart networking or reboot:

sudo service networking restart

@2707974 's answer will produce:

SIOCSIFADDR: File exists
SIOCSIFFLAGS: Cannot assign requested address 
SIOCSIFFLAGS: Cannot assign requested address

Sadly I don't have enough points to comment under his answer.

Updated my answer: @2707974 pointed out that my original answer was bogus -> see question.

If are devices connected to the same switch you simple can add virtual interface

sudo ifconfig eth0:1 192.168.2.xxx netmask 255.255.255.0

You will have one nic with 2 ip address, but only network 192.168.1.xxx will have default gateway.
