These cameras can be viewed and controlled from a standard Web browser, video display, or even a compatible cell phone or PDA. 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. Equipped with a 10x zoom function, the camera lets you zoom in and out in a total of 10 steps to view objects that are close or far away. You can feel more secure because the zoom function gives a clear view of objects that would be difficult to see with ordinary monitoring, like the face of a visitor walking through the door or the detailed conditions at the back of a large factory.
