IP based Closed Circuit Television is becoming increasingly popular over traditional analogue video, mainly due to quality of images and simplicity of installation.
Up to 3 mega pixel quality can be achieved giving a superior image quality, and with POE networks it is possible to power the camera direct from the network removing the problem of installing local power to the cameras.
Cameras can be either static - looking at an entrance for example, or can have Pan, Tilt, and Zoom functionality - these type can cover a large external area, and be programmed to 'tour' preset locations, zooming in on areas if needed.
Using the latest IP Cameras, images streams can be recorded, viewed and controlled via PC's over a Local Area Network, remotely via the internet, or even by handheld devices such as Windows mobile phones, iPhones, or PDA's.
