Yes. More correctly, it should be terminated with a 50 ohm load, but
I've never seen any harmful effects from just leaving it disconnected.
If the camera is located VERY near another source of 802.11b/g
interference, I would suggest looking into a terminator. If you can't
find a terminator, just cover the connector with aluminium foil and
tape to prevent the connector from becoming a very small antenna.
I'm not sure if there's a setting in the web based setup to select
only one antenna. If there is, please use it.

No. The radio is switched between the two antennas. The idea is that
if one antenna is not getting a sufficient signal (due to multipath,
fade, obstruction, or position of the moon), the other antenna may be
able to get a better signal. This is called positional diversity.
There are configurations where you would want to have both antennas
active, but a point to point link is not one of them.

Transmit power? Well, you're correct that it's not on the DLink data
sheet.
Find the FCCID on the serial number label. Then go to:
https://gullfoss2.fcc.gov/prod/oet/c...ericSearch.cfm
and see if the broken FCC ID search thingy will find it. If not,
inscribe the first three letters of the FCCID into Guarantee Code
search box. Leave the Product ID blank. Go to the bottom of the page
and increase the Result from 10 to about 100. You should get a list
of everything made by this manufactory for Dlink. Search for the
product code or model number.
On one of the reports are the "test results" which include the real
power output, receiver sensitivity, and such.
