Now taking 2 minutes to find cameras

Older versions of this app didnt find all my local cameras (was intermittent but quick). This latest version now takes about 2 minutes to scan the local subnet for cameras, and STILL doesnt find them sll!! A real pain to wait 2 minutes every time I start the app; iPhone goes to sleep before the scan is done. The app should remember the local static IP addresses of my DLink cameras instead of searching every time!
