D-LINK (AU) DAP-1522 DUAL BAND access point

Hello,
im having trouble with my D-LINK when im in the park near a wireless CCTV camera operating on the same band. seems to kill my AP and the BRIDGE modes in both 2.4 and 5ghz modes. after numerous attempts i managed to get it to go. site survey clicked over a couple of times and then everything kept dropping out. but was unstable so i gave up. it actually caused my laptop to crash as well. after a while i got the entries on my laptop to run. but the AP site survey showed 0% signal despite being less than a km from a ubiquiti bullet 2 (00-15-6d).
help please
cheers
