9v Belkin Polarity Will This AC Adaptor Work This Wireless Router?

Will this AC Adaptor work this wireless router? - 9v belkin polarity

I have a Belkin Wireless Pre-N Router Model #: F5D8230-4 at home.
The plug-in power on the router DC12V/1A said. I found two AC adapters I have, but I'm not sure I go to work? One of them is 12V 500mA output and the other is 9V 800mA. Work with the router? I'm not sure if it comes with the router or not.

The camera is activated when you connect the power adapter 12V 500mA connection. I have not tried the adapter 9V 800mA b / c I do not want to break it. They have also tried to use the router for the same reason.

Any help would be great. Thanks
