I bought this cheap home camera to watch my dogs stay in alone. The installation on the Mac proved to be very treacherous, the Safari browser is completely unsuitable! With Firefox everything worked right away and I can now watch my hooligans stay on alone. App on iPhone 4, software on iMac and MacBook Air now works perfectly, picture quality is moderate, but totally adequate for my use. 4 stars for the excellent value for money and ease of use, if you know a bit with computers and software!
