The development of computer technology today has reached a significant scale. This development is most clearly seen in metropolitan areas and simply large cities. Computer use is ubiquitous. Security systems are no exception in terms of computer development. The use of a computer as a universal machine is especially important in the issue of working with an image. The security system that provides images and takes pictures in the right places is video surveillance. There are two types of video cameras on the market of modern security systems: digital IP cameras and analog ones. The history of the emergence of IP looks somewhat comical. According to one version, the students who lived in the hostel were unhappy that someone was constantly stealing their coffee. The solution to the problem was the creation of a camera, with the ability to connect to a computer.
First of all, an IP video camera is convenient for use in combination with a computer, since it is a portable computer in itself and has its own operating system. The development of some programs, setting up individual features of the work, is possible if you have knowledge in the field of programming. Like a computer, a digital video camera can be integrated into various security systems. We are talking about the installation of additional sensors, as well as various readers. The role of a reader in an IP video camera can be designed to obtain information about faces, car numbers, barcodes, etc. The digital video camera can be controlled using both wired communication networks and using Wi-Fi, Bluetooth or the Internet. Using the Internet is convenient in cases where it is necessary to be at a considerable distance from the protected object.
The external forms that an IP video camera has can be the following: case, frameless and dome. Box cameras have additional mounts included. The purpose of these mounts is to secure the camera to a wall or ceiling. The advantages of box cameras are the availability of interchangeable accessories. During the installation process, it is possible to purchase the most suitable lenses, mounts or power supplies. The presence of the body serves as a kind of protective barrier. Thus, this type of camera is well protected from precipitation and exposure to high and low temperatures. Regarding dome cameras, they are by far the most popular in the field of video surveillance. This trend is due to the fact that dome cameras are small in size. The unremarkable form allows you to create the impression of a certain lighting device, signaling. In turn, dome cameras differ in the principle of lens movement. Certain types of body cameras have a wide rotation area. However, such a moment can negatively affect the image. Modern developers are designing cameras in which the movement of the lens will not affect the quality of the video. In general, lens rotation is an attribute not only of a dome camera, but of many others. The convenience of this opportunity is primarily economic. First, PTZ IP cameras require less than static ones. Secondly, by using fewer cameras, fewer power lines are required. As for open-frame cameras, their design provides for the placement of the lens directly on the board of the camera itself. The use of such cameras is convenient in various types of covert surveillance.
IP video cameras are universal in the video surveillance system. The tasks that a digital video camera can perform are extensive. So, for example, the ability to fine-tune the focal length allows you to create a scalable video monitoring system. The use of a digital video camera provides the user with many settings that can best meet the requirements of video surveillance sistems. From IP cameras it is possible to receive video recording online, without compromising quality. The video that is broadcast from surveillance cameras is provided simultaneously with the sound. The exported video can be passed through various converters. This process is necessary if the device where the video is uploaded has a small amount of memory.
The scope of IP video cameras is quite wide. So, the most common example of use may be the creation of video surveillance systems. The next advantage is the implementation of remote control over the selected object. If necessary, a digital video camera can be used in the field of control, over the process of implementing a specific project (construction, trade, etc.). In the case of various incidents, the material of a digital video camera can be used as evidence. IP cameras are used even by various marketing areas that are not related to security or are indirectly related. An example is a visual representation of various hotels, beaches, resort areas.
From the point of view of control and security, IP cameras have established themselves as high-quality equipment in the field of security technologies. The undoubted advantage of such cameras is the ability to connect to various communication lines that are configured to work with a computer. As for the captured video, there is the possibility of converting the footage, saving it in accessible formats, and recording sound.
