Security Systems and Surveillance cameras

The modern market for security systems provides many different systems and individual technological devices. The development of technology today has reached its maximum high level. The use of various security systems is not due to a narrow spectrum of action. Surveillance cameras are a good example. Today, CCTV cameras are presented in a very wide range. The use of such cameras is possible in various security systems. Simply put, video cameras are easy to integrate and adapt to the work of the required system.

Criteria for Selecting a Surveillance Camera

When choosing the right surveillance camera, you should consider for what purposes and conditions the camera will be used. It goes without saying that the surveillance camera will be used in one fixed location. The conditions that dictate this very place are directly the conditions that the selected camera must meet. The first indicator of the camera is its price. Naturally, a surveillance camera that has various technological features will cost more than a more primitive camera. Nevertheless, it is sometimes more expedient to use a cheaper analogue than a technologically developed device. The following example confirms this statement - when the camcorder is set to face recognition. Requirements for such a video camera: color and high resolution, denser arrangement of pixels. As for the camera, which is focused on recognizing the license plate, it is better to use a black and white video camera. This example characterizes the possibility of integrating a video camera into an access control and access control system.

Features of Working with Cameras and Surveillance Systems

The use of any video cameras, alone or in a system, requires certain knowledge in operation. Essentially, the camcorder itself is a tool. The correctness of use and subsequent action is the merit of the observer. One of the factors that must be taken into account is the attentiveness of the observer of what is happening in the field of view of the video camera. It has been established that attentiveness decreases in the process of observation. To eliminate this effect and attract the attention of the observer, a special kind of software has been developed that changes the focus of the camera, fixing it at certain moments. This example indicates the need for briefing among employees, on the part of the installer of video cameras In general, the video surveillance system must undergo certain types of inspections and preventive maintenance. The most common type of such work is cleaning the video camera from dirt, additional focus adjustment. Checking communication channels, power supply are also necessary components of preventive work.

Color and Monochrome Surveillance Cameras

The main difference between the video cameras presented today is their operating conditions, color, and the possibility of expanding the functional spectrum. So, the simplest are analog video cameras. They are represented by the simplest mechanism. As a rule, analog cameras are black and white. The area of use of these cameras extends to various types of intercoms, car DVRs. As for management, it is carried out using the controller (the brain of the system). In general, analog cameras have a lower price and image quality is also lower than digital ones. In terms of connectivity to a computer, digital will also be better. However, analog cameras also have certain advantages. Shooting in twilight or night lighting conditions is better on black and white cameras. Modern cameras are equipped with special technology, in the process of changing the lighting, the color of the shooting changes. In the daytime, color shooting is carried out, in the dark - black and white.

Digital IP Surveillance Cameras

As for digital video cameras (otherwise IP video cameras), their scope is much wider. This is mainly due to the fact that IP video is easier to convert with a computer. Also, this type of signal does not lose quality during the copying process. The spread of computer technology naturally popularizes IP video cameras. Also convenient in IP video cameras is the ability to use wireless communication (wi-fi, bluetooth), however, this type of connection is good when the distance between the cameras and the video surveillance system is not large. Connecting an IP video camera to the Internet will allow you to receive an image from it anywhere in the world. In general terms, this camcorder is a portable computer. The development and installation of various individual programs is possible even for the owner of the camera.

Surveillance Cameras and Human Activity

Over the past decades, video cameras have become an indispensable attribute of various spheres of human life. The use of cameras can be found in absolutely unexpected places. From various spy gadgets to serious objects. Different camcorders are adapted to different conditions of use. Surveillance cameras that are mounted on the street have additional degrees of protection against precipitation, high and low temperatures. The cents of such cameras will be correspondingly more expensive. It is also important to note that outdoor camcorders may have additional power supplies. Modern processing, careful adjustment contributes to the optimization of the video camera for the mode of the existing object. Such characteristics are available mainly to expensive camcorders. On the other hand, there are a number of cheap video cameras, with less technological equipment. They also find their scope.
