The Periscope HD turns your spare iPhone or iPad into a fully functional wireless IP camera. Watch your home, kids, and pets for free. No configuration is necessary when using the Periscope Pro. You can search the Mac App Store for "Periscope Pro" or enter bit.ly/periscope_pro into your Mac Browser. To use Periscope HD without Periscope Pro, check the "Preferences" tab for RTSP URL. Then put it in your favorite RTSP-enabled video player/IP camera viewer. It should work, but we didn't test it. Technical specifications: Video: H.264, 1280x720, 30 fps; Audio: G.711 PCMU 8000 Hz; Networking: RTSP over UDP, RTSP over TCP; Bonjour.
