Accesing device in my subnet with a fixed IP

I've just purchased a cheap surveillance camera for my apartment. However, while the subnet in my apartment is 10.0.0.0/24, the camera comes with a fixed IP of 192.168.1.10. You can change the IP, but you have to coect to it first.

I can see in Wireshark the unanswered arp requests of the camera to 192.168.1.1. So I decided to 2 arp entries in my computer to bind for 192.168.1.1 (direct it to my routers MAC), and to 192.168.1.10 (direct it to the camera's mac).

I set those entries to be "published", I thought it means my computer will answer for an arp requests of the camera, and the router.

When adding the router as a published entry, with this command line: sudo arp -s -i wlan0 192.168.1.1 e8:fc:af:89:c6:e0 pub

I get this entry - 192.168.1.1 * "from_interface" MP wlan0

Unfortunately, my computer doesn't respond to any of the camera's arp requests.

Am I taking the wrong approach here? What can I do otherwise to access the camera? And why wouldn't my computer answer to the camera's arp requests?

(I'm using ubuntu 14.04)

Thank you.
