I'm not clear from your description, but I think you're trying to do DHCP on networks which are remote from the machine running dnsmasq: The 192.168.21.x etc networks have an interface on the tracking machine, and the camera, but not the Debian machine.? In that case you need to run a DHCP relay on each tracking machine, which will collect the DHCP requests from the camera and forward them to the Debian box. Something like dhcp-helper or ISC DHCP relay would be fine.
