IP Cameras

If you are a business with a IT network installed you could take advantage of IP cctv cameras. They work by turning images and audio into data then transmitting this data over a network or Internet connection. The ultimate benefit of this over analogue CCTV systems is greater flexibility, better performance and easier installation.

Whilst IP cctv has been available for around 10 years, it is only in the last few years that the technology has matured, leading to the developments in Megapixel IP. Read below for a summary on the benefits of using IP based systems over traditional analogue systems.

CCTV Recording

A dvr is a digital recorder, replacing the old video recorder.The dvr has a hard drive which it records the images to. So no more changing tapes everyday.The dvr can include a CD writer for copying images to a disc from the hard drive for evidence. Also there is a LAN connection for IT integration or offsite monitoring.

Many local authorities require that certain types of business premises, especially those that open late into the evening, have an operating camera system with digital recording facility as either a term of their licensing agreement or by law. Pubs, clubs, restaurants and similar businesses are finding that they are being required to fulfill more and more different requirements and the presence of a working CCTV system is an ever increasing license rule for these types of premises.
