These cameras can be viewed and controlled from a standard Web browser, video display, or even a compatible cell phone or PDA1. Place them in your home, office, vacation home or almost anywhere else that you'd like to keep an eye on things, with no PC required on location!. They are easy to install and operate and require no additional software for the PC that you're viewing them on. Each camera also comes with a free Web address, which can track the camera automatically. All you need is a regular Web browser to view them on your PC, as all of the other required software, including control software (TCP/UDP) and e-mail software (SMTP), is already inside the camera. This camera can communicate wirelessly with standard 802.11b or 802.11g wireless devices, allowing the flexibility to install and operate the camera without running network wires, and utilizing SSID filtering and powerful 40/64/128 bit WEP encryption helps to protect your wireless network from illegal intrusion. This network camera is truly easy to install and use in most cases. With industry standard automatic configuration (UPnP), the camera and your router or PC will automatically decide the best settings allowing you to access your camera without any complicated setup. Once connected, using a simple Web browser, just enter in your free, permanent Web address which comes with the camera and you can see and move the camera! It's that simple.
