This Wifi b/g wireless IP camera has its own built in web server. You can view the video from your own home network or you can configure your router to view and control the camera from computers or cellphones on the internet, without dependence on any third party web sites or subscriptions. With the built-in microphone you can listen in. Excellent MPEG4 or MJPEG video quality at a full 640 x 480 resolution with up to 30 frames per second for fluid, natural motion color. For viewing or recording a single camera no software is required besides just your browser. For viewing or recording multiple Sharx IP cameras the included MultiView software for PCs supports up to 4 Sharx IP cameras simultaneously. Truly amazing to see the streaming video on your web enabled cell phone. For frequent use we recommend to upgrade your cellphone service to unlimited data, which costs just $15/mo extra on the ATT network. You can see motion even on non-3G phones like SonyEricsson w580i. If your phone does not support video you can see automatically refreshing JPEG images. At home, you can use this camera with your laptop or iPhone as a baby or pet monitor, and the very high light sensitivity in "moonlight mode" allows you to view out from a window to see what's happening in the street as long as there is some background light available. This camera has infrared night vision which can see in total, absolute darkness. Like any infrared sensitive camera, the daytime colors are subdued and can appear unnatural especially on plants and vegetation. For eye-popping, gorgeous daytime colors please select the less expensive Sharx SCNC2606 camera if you do not need night vision in total darkness. Wireless operation supports WEP, WPA, WPA2 encryption. On routers with UPnP feature the camera can set itself up automatically, and on routers without UPnP (such as Apple's Airport series) the camera can be set up with our step by step instructions.
