Safety – PoE is an intelligent system and protects equipment from incorrect installation, power overload, or under powering. Location of cameras – as cameras do not require a power outlet, they can be located anywhere and can be relocated easily if required. Network cables do not require a qualified electrician for installation. Saves time and cost – savings can be made by not having to install electrical cabling. Camera Cables and ConnectionsĪn effective CCTV camera system requires correct and high quality cabling and connectors to connect the components of the system together. There is also reduced sensitivity to noise. DSP camera benefits include increased brightness, greater stability of image, a sharper image and better power efficiency. The analogue signal is generated by a CCD chip (charge coupled device – see above) and then the DSP chip converts to digital.
The NVR streams the video from all cameras and broadcasts over LAN and over the internet for remote viewing.ĭigital signal processing cameras utilise a DSP chip to convert analogue video signals to digital. The key difference is that the signal is digital and a much higher resolution (see further down in this guide) than analogue. Instead of the analogue system’s DVR, for IP cameras, the video from each camera is compressed and recorded onto an NVR (Network Video Recorder). The digital signal is then sent via a LAN (Local Area Network). Digital processing may also occur within the camera. With digital IP (Internet Protocol) cameras, each camera captures an analogue signal, but this is converted to a digital signal within the camera itself. The charge on the diodes are then processed. The photo diodes form a matrix of rows and columns and are called picture cells or Pixels. A brighter area will result in a higher charge. Photo diodes sense the image areas of light and dark and this results in an electrical charge in proportion to the level of light. The camera lens focuses light on the CCD image sensor. The CCD is made up of optical detector integrated circuits that use semiconductors. Signal processing converts the electrical signal to a video signal that can be displayed on screen or recorded. This converts light into an electrical signal.
At the core of a CCTV camera is a CCD sensor (Charge Coupled Device). The main function of a CCTV camera is to capture light and convert it into a video signal. Each section of the buyer’s guide below will inform you about the different aspects of cameras. When buying a camera system, many factors must be considered, for example how the system will be used, technical CCTV camera specifications and constraints of the environment into which the system is installed.

IP camera is a digital video camera that can send and receive data through internet and widely used for surveillance from anywhere in the world. But in the year of 2005 first IP camera with onboard video content analytics (VCA) was released by Intellio. Later the first decentralized IP camera was released by Mobotix in the year of 1999.
