Works fine. Most of the bad reviews are from clueless kiddies who want to snoop cams – iCamViewer: CCTV Camera Pros Review

This app works FINE. It even works on my old iPhone 3G. It is a "serious" app for users who own and configure their OWN IP cameras. It IS *NOT* a toy for kiddies or voyeurs to detect & snoop on their neighbors or local store security cams, or view a random list of cameras somewhere in the world! A bunch of useless reviews from stupid people! You must know the Camera Model, IP Address, port and password for the camera(s) you want to configure. And it DOES show "live" images. On my DLink 6620G the updates were about 5 seconds apart. It does the job as advertised, but it does not have any advanced features. For example, there are no controls for PTZ cameras, at least not for the DLink. The rest of the selections in the icon bar are "infomercial" material by the company that sells Video Surveillance Hardware. Therefore it earns a 3 star rating.
