IP CCTV (Internet Protocol)
Internet Protocol CCTV (IP-CCTV) is the future of CCTV.
Internet Protocol (IP) is the universal standard used connect smart devices over a network or the internet. Using IP in CCTV allows for cameras to have an in built intelligence which is used to control, configure and manage image transmission.
IP-CCTV permits the use of very high resolution cameras (HyperHD) with currently up to 30 times the image detail of standard CCTV and this set to increase even higher.
As all components in an IP environment work to the same communication and control standard it is easy and convenient to exchange or upgrade a component individually without having to change the whole system. Even the power requirement for devices (cameras) can be carried on the same cable as the communications signal (PoE Power over Ethernet) .
Integrating an IP-CCTV system into an existing IT infrastructure is also easy as both systems are talking the same language.
Another major advantage of IP-CCTV is that the system is ready for future developments as they too will be developed to the same IP standard.
Currently cameras are available from 2 to 10 mega pixels and there are cameras in development that have 20 mega pixels. High resolution cameras allow for the zooming in of an image without a perceivable resolution loss. As an example the Home Office guidelines recommend that to identify a car registration mark (number plate) the plate should fill at least 1/8 of the picture at standard resolution. Using a 5 mega pixel IP camera it would only need to cover a 200th of the screen area to have a clearer image.

Another major advantage of IP-CCTV is data management.
It is possible to be viewing a wide view of lets say a car park and at the same time from the same camera be viewing a close up view of a number plate. This gives control to the operator to decide what part of an image he or she is viewing requires a closer look without the need for a mechanical zoom or positioner it is as simple as clicking the mouse on the part of the image one wants to see in more detail.
Having each component in a IP-CCTV system with its own intelligence allows for each of these units to do certain very tedious but vital tasks automatically.
This could be as simple as triggering a full screen of an activity in a restricted area and sending a alert email or it could be advising the system that the camera lens needs cleaning.
With all components able to communicate with each other, complicated processes involving many components can be performed. It is and also possible for parts of the system to be integrated into other IP systems such as computer networks, servers, door entry systems and so on. Being smart and able to communicate most control and configuration can be done by the technician remotely.
