[QUOTE="Flying Scotsman, post: 266, member: 20"] Remote CCTV: Remote CCTV is the means of accessing CCTV images over a computer network or standard telephone networks. Software is used on the local PC that allows access to the digital video recorder. IP CCTV: IP CCTV refers to Internet Protocol Closed Circuit Television; traditional CCTV systems use digital or analogue cameras using analogue cables that connect to a recording device such as a digital video recorder. IP cameras are designed to plug onto any existing wired or wireless computer TCP/IP network, or directly onto a broadband connection so that the camera can be accessed by any computer connected to the network, this includes over the internet. Computers are used on the network to store the camera images but with the flexibility of IP CCTV, the cameras could be located on opposite sides of the world. Although IP Cameras can be connected directly to an existing network, bandwidth is always a consideration as the data sent from the camera is likely to be much larger than standard data transferred over usual office networks which if not planned correctly can slow down the entire network. Video Signal: The video signal is known as the moving image information signal produced from a video camera, In the UK we use a video signal standard called PAL (Phase Alternate Line) this is a colour or monochrome video signal that comprises of 25 images or frames per second. The PAL video signal is common to most UK TV [/QUOTE]
