Yes, the embeded IP Camera is running uClinux and supports ethernet/wireless
interfaces. Two interfaces work fine in different subnet. For example, ethernet
interface can be used for the Internet access (real IP address) while wireless
interface interface can be used for the LAN access (virtual IP address). The 
two inferfaces working in the same time do have the advantage in some situations.
 
Because it will be a product, I need to consider every possibile situation that
ordinary customers might have after they buy IP Camera home. The situation
I post is just one of them I am thinking of. 
 
If there is no better way to solve "two interfaces in the same subnet using Linux"
problem, user manual might need to state "if wired and wireless interfaces are in
the same subnet, only one of them gonna work". Or use a HW switch to switch
between wired/wireless to make only one infterface work at any time.
But it will be considered a drawback/less-feature, for some of interested buyers.
 
thanks for the replies and helps :)
