If the camera has to be additional protection against possible assault, choose dome cameras, because it protective housing. In such a chamber is a great review and implemented a progressive compression of video. For remote monitoring via the Internet fits IP-camera transmitting the image through the built-in server on your computer. This provides an opportunity for remote monitoring of the protected object. IP-cameras have been recognized and spread very quickly in the market system cctv. IP-CCTV system is effective, not costly, and simply plugs can be easily mounted in a house, apartment, office, at the door of the building, in hallways, offices. IP-camera increases productivity and responsible office workers, production and protection, will reduce the possibility of crime in the workplace. Home is convenient to use IP-camera, because it does not restrict the distance from the object observation to the observer, see the reference object can be anywhere where there is Internet. In supermarkets, IP-camera warns of committing theft of an unscrupulous buyer or employees of the store.

Observation of objects over an IP-camera became popular and gained the status of entertainment to attract an increasing number of visitors to the author web-sites. As mentioned above, the installation of IP-camera does not require installation wiring, placement Monitor surveillance and control systems, because it built the network card, SMTP-server and Web-server. This camera can operate autonomously, without need to connect to a computer, installing and configuring special programs. All that is needed for IP-CCTV, an IP-camera, and wired or wireless network connection. Given all this, we conclude – IP-camera with a relatively low cost, easy to use and configure, does not require complex assembly of the installation and laying of cables, allows for the easiest access to the video from any pc with a network connection. Price surveillance system consists of several components. This equipment and transmission system images, and software. Common surveillance system can monitor the object from a distance, making the record as all that is happening in the lens installed surveillance cameras, and the moments in which there is any change in the scene (thanks to Motion).

If you want to install a network camera wirelessly, the cost of such a system observations will be higher. The popularity of video surveillance systems is growing worldwide, as the modern society faced a serious security problem. This is reflected in the prices surveillance. Technology developed in downward price with improved video. Occurs cheapening the main part of a surveillance camera. The market surveillance systems beyond many countries with low labor costs, which also affects the prices fall equipment for video surveillance. Surveillance system with wired and wireless IP-based cameras, need to be connected to the Internet via a modem. Still need special software for network cameras, it is ever present in any IP-camera, but can not provide all the methods of processing video sequences, such as recording and subsequent storage, simultaneous viewing of two or more sources.

Take care of the heat efficiency of any heating system has the property over time to fall, usually as a result of gradual fouling of pipelines, heat exchangers, pumps and radiators hardness salts contained in water. It is estimated that millimeter deposits on the inner surfaces reduces heat transfer up to 20%, and this in turn entails an increased consumption of energy source to maintain the required temperature in the rooms. Hence the need for cleaning of heating almost any heating system. And in this case it may be noted that “Progress” also allows you to use more effective methods of treatment. Thus, by “Gidroflou (UK), developed special equipment to clean and protect from scale and deposits of heating systems, boilers, boilers, heat exchangers, steam generators, etc. The principle of operation of such devices based on the use of high frequency electromagnetic pulse generator with variable frequency. Generated impulses cause formation in solution, the tube axis, the nuclei of crystals of various salts.

The mass of the solution created by the nuclei is the growth of crystals with dimensions of about 50 microns. After this, crystals were carried out of the system with water flow. At the same time setting protects the pipe from internal corrosion: field generated by delaying the free electrons of the metal on the outer surface of the pipe, impoverishing the metal atoms at the inner surface of the pipe and thus blocking electrochemical reaction. Efficiency of the heating system may be reduced as a result of dirt with faulty sumps. Sump blockage is determined by the testimony of gauges installed before and after him, according to increase in pressure drop. Eliminated the obstruction through the mud sump outlet drain valves at the bottom. If this way clogging persists, then the sump disassembled and cleaned the grid and the inner surface. For Prevention of this problem must be regularly servicing sump installed in the heating unit building.

Generally, the operation of the heating system in a private home or apartment building needs regular diagnostics that will identify and eliminate these and other problems.
