IP Cameras

Voice communication on the telephone is still the most preferred method, but mainly text-based communication replaced the letter, such as e-mail and MSN Live Messenger is messaging software. Because these new methods, often much more quickly and free. Moreover, the webcam video chat free software can do those. To this effect, a web camera sales exploded. USB port for external devices are today's most popular web cameras on all the USB connection is used, the additional power is required. It's very simple web cameras that have a receiver and the converter circuit. The majority of medium-consistency of image quality and do not have any optical zoom. After all, the prices dropped to the level of $ 10. This is a simple product to set aside the time to look at the advanced options. Access to IP cameras can be installed over the network from different points, do not have to remain open to any computer. In addition, the images at the same time be able to follow simultaneously connect to multiple users. Just think of comes from traffic cameras. Established to transmit the traffic situation at a specific point in this kind of public benefit of the cameras is indisputable.

Linux operating system installed on the same general principle. IP camera, the image contained in the receiver circuit provides an electrical signal after dialing sharing over the network. This allows the transfer of the image processing circuit, and not so simple. Often we can define a simple computer with Linux operating system installed. The first IP camera was developed by Axis Communications in 1996 and this device was also included in the Linux operating system. In addition to being free to be open-source Linux is an advantage. Preferred to communicate with other devices, thanks to universal standards does not the problem. Brand, brand methodologies and protocols used to transfer data does not differ. Indeed, IP cameras, network devices with a specific IP address. We can make access to computers on a network file and printer sharing. IP cameras, IP addresses can access a similar way, the image pass on our computer and the sound is supported. At the same time can use a single computer, such as IP camera, on the contrary, many a computer with multiple IP Cameras can be connected simultaneously.

A large number of security camera

This method is preferred for security in the central station computer and the software can be connected at the same time from each of the image from 16 IP camera dizebilir smaller windows on the screen. Thus, protection of images from IP cameras placed in different points of the field by a single person can be monitored continuously. This system gives much more successful outcome follow-up alternately. Each of the cameras are set to receive a separate IP address. Most IP cameras have built-in feature of DHCP. So dağıtmıyorsa camera attached network device makes the connection with DHCP IP automatically receive an appropriate IP. This is of course a method is not preferable. Because the camera is turned off and then clients connecting to the IP number can vary and is forced to learn a new IP number. It is convenient and preferred to provide a static IP address IP camera. If you have multiple cameras 192.168.1.100 - 192.168.1.115 distribute a range of static IP addresses.

Resolution, refresh and lighting

IP cameras, Web cameras and digital cameras as well as a significant degree of resolution of the recipient. In general, the VGA 640 x 480 pixels in order to understand what is going on smoothly enough. However, this resolution, refresh rate should be considered. Sometimes, producers, and 30 fps in VGA quality icon sets. But inince detail 320 x 240 pixels (QVGA) 30 fps and 10 fps in VGA is understandable. Need for smooth video at 24 fps. Except for the resolution and refresh rate sensitivity are also important. The weather may be impossible to use the decision as a security camera image disappears. LEDs for the lighting is dark on some cameras. You can control them via software. Always open, always open or closed as necessary, should be able to select. Upper-level models is the engine that allows movement. Deception is a kind of non-motorized models on the basis of the possibility of action. First, the digital zoom is done, focusing on a point within the image area is after already acted as if the camera is given the impression.
