What happens if you add an arp entry for your camera by hand after
you start hostapd, but before the camera joins the network?
arp -s 10.0.0.3 00:00:85:ff:81:cc
(If this works, then I'm afraid you have to take your case to
linux-wireless at vger.kernel.org and Cc rtlwifi maintainers:
Larry Finger <Larry.Finger at lwfinger.net>,
Chaoming Li <chaoming_li at realsil.com.cn>. As it sounds like
the AP driver/hw has problems with delivering broadcast
frames (arp-requests in your case) at the "correct time"
(i.e.: right after a DTIM beacon (every third beacon in
your case / every ~307.4ms)).
