Can your ip camera be configured to ftp images out?
if yes, you can set your camera to send images out to some service provider for the storage, such as [mod edit - advertising removed] and view your recorded images via your HTC
when you sign up an account with [mod edit - advertising removed], your can then access your cameras images via [mod edit - advertising removed]
no APP is required to download
Real good solution, very reliable, strongly recommand
You will save a lot of money to purchase a storage device and more importantly, save all the trouble to set up the ddns for remote access.
