Surveillance ? IP cameras
 
IP-camera - is permanently installed camera, which has a built-in IP-server network interface and connect directly to the LAN / WAN / Internet. Most network cameras have such additional funds as: motion detectors, sending messages on e-mail, work with your modem connection of external sensors etc. Users can access to the camera via a standard IP browser. Depending on configuration, access to the video, obtained by IP-camera can be open to all network users or authorized users only.
It consists primarily of sensor control. Very often, instead of standard CCD-matrices for video used cheaper CMOS-sensors. Although they have more low sensitivity and is not too good color reproduction, their use can greatly reduce the cost of the device, because these sensors are «all in one chip» with digital output data.
Next: in the network camera includes a microprocessor for the compression Video and Motion Detection (or simply chip is a compressor). The most popular JPEG, as the most simple and cheap, enough often used as MPEG4, the most rare and expensive is MPEG2. With the completion of the patent on arithmetic coding gains popularity WaveLet. Finally, in the network camera includes a network controller, 10/100 Mbps.
Modern IP-camera is a digital device that produces the filming, digitization, compression and transmission of video over a computer network. Therefore, in the IP-cameras includes the following components:
- CCD
- Lens
- An optical filter
- Video capture card
- Block compression (compression) video
- CPU and built-in IP-server
- RAM
- Flash Memory
- Network interface
- Serial ports
- Alarm inputs / outputs
In as a photodetector in the majority IP-cameras use CCD (CCD, CCD - charge - coupling) - rectangular photosensitive semiconductor plate with the ratio of sides 3:4, which converts the incident at her light into an electrical signal. CCD consists of a large number of light-sensitive cells. In order to improve light sensitivity of the CCD, often form the structure, which creates a microlens before each of the cells. In technical parameters of IP-cameras usually indicate format CCD (the length of the diagonal matrix in inches), the number of effective pixels, the type of scanning (progressive or interlaced), and sensitivity. A typical IP-camera contains a lens, optical filter, CCD, scheme of digital image processing, image compression scheme, and IP server to connect to network. Each network camera has its own IP-address, computing functions, and built-in software that allows it to operate an IP server, FTP server, FTP client and client e-mail. Most advanced network cameras and includes many other attractive features such as motion detection, input / output of anxiety and support e-mail.
With built-in IP-server, to send the resulting image on the network, the network camera does not need a direct connection to a computer or any other hardware or software.
