    For oil boiler you will need to book regular supply of fuel. Environmentally, the lack of odor, no need to install a chimney – a few more advantages of electric boilers. The division of boiler fuel consumption by type of gas boilers, using natural and (or) LPG, propane and oil boilers (diesel fuel, diesel, biofuels, and various engine exhaust oil) solid fuel boilers use coal as a fuel (coal small coal), wood (pressed sawdust, wood, wood waste) power, use a heater or hydrolysis. Where possible shortages electricity, electric boiler is often used in conjunction with a redundant solid fuel. It is worth noting that when installed in big cities with strict environmental regulations and issues approvals, electric boilers often outperform all other types of boilers (including gas). In summary there are a number of advantages of electric boilers buderus, herz: low price, easy installation, lightweight and compact, can hang on the wall as consequence – saving space, safety (no open flame), easy to use, do not require a separate room (boiler room), do not require installation of a chimney, do not require special care, quiet, environmentally friendly, no harmful emissions and odors. Among the publications on the subject of heating the vast majority of material relates to gas and liquid fuel boilers, and it is very difficult to find anything about electric boilers. And if any articles they are mentioned, they often are limited to two basic types of phrases: 'electric boiler is not suitable for homes with an area of over 100 sq.m' and 'power electric boilers not exceeding 15 kW.

    " In fact, this is not true and there is no reason to bypass attention to this type of boilers. It is clear that much more expensive than electricity and gas more expensive than diesel fuel. Clearly, if next to your site runs a gas line, it is logical to choose a gas boiler. In all other cases, it seems to me, do not so peremptorily declare that such devices as ball valves, heaters, radiators are suitable only for heating the smallest of spaces and seriously consider them not. Also not true to say that domestic electric boilers produced only a small capacity. Even if we take into consideration only the most well-known company in our market, it is not hard to find electric boilers in the 60-100 kW, which can heat rooms up to 1000 m2.

    Moreover, this dome camera series can broadcast in parallel NEYRO one or two video streams with individual settings for each parameter: the administrator can choose the video codec, resolution, frame rate, etc., based on the requirements for the monitoring system of the object. STC-IPX2050A equipped with 1 / 4 'CMOS-sensor and the original processor, providing an informative image forming light to 0.1 lux, and can choose the resolution: Full D1 (720×576), VGA (640×480 pix.), CIF (352h240) or QCIF (176h144piks.) and video bitrate up to 25 / sec. To work with various lighting a new dome camera uses a software mode "day / night", so that can automatically switch from color video to black and white and back again, when the threshold illumination level. Improve the efficiency of video observation allows bidirectional audio communication between an organization object, where the camera and putting the security services, as STC-IPX2050A equipped with audio input / output. Built-in video analysis algorithms provide VCA presence STC-IPX2050A ability to detect and identify objects and people in the surveillance zone, which can be set arbitrarily, as well as tracking multiple objects (to 100) and control manipulations on the very dome camera: the unauthorized change of sector monitoring, defocusing, or closing the lens shading. In this dome camera can be used as a stand-alone sensor alarm, and its alarm output – connects to the activation of recording systems or alarm systems. If you change the lighting on the site analytics algorithms automatically adjust to the new conditions of work, so the likelihood of false positives is always close to the minimum.

    Advanced analytics camera offers an optional package VCA surveillance, which allows classification of objects by size and speed, to set "acceptable" and "inappropriate" direction, stopping to fix the object in the wrong place, or delay in the controlled area for longer the allotted time, etc. In addition, the dome camera that incorporates a VCA surveillance, may be to count the number of objects over time: in ascending and descending order, to calculate the intensity chelovekopotoka, and also supports filter "double border" when an alarm is activated only when crossing one and the same object, two boundaries located at a distance from each other. View video from the camera can be in real time via any web browser, whether it be Internet Explorer, Mozilla Firefox, etc. However, for full control and customization over 3 STC-IPX2050A require specialized software. Like other cameras leading manufacturers, this Dome works with proprietary software NetStation, which is intended to create IP-based surveillance of various sizes and allows the current observation, record, search and playback of video from the archive, and also search in the archives of the fragments on the movement and use of graphic plans eMap. Under the brand name Smartec, a wide range of equipment to create classic and IP-video surveillance systems of any configuration and complexity. The product line includes analog and network cameras (B / W, color and day-night), domes, 4 -, 8 -, 16 – and 32-channel DVR, 17-32-inch LCD-monitors, IP- cameras, varifocal lenses, IP-video servers, housings, infrared illuminators, brackets, power supplies, etc. The main competitive advantage of equipment Smartec – this functionality, high quality and reliability of the devices when they are affordable, as well as the presence of Professional technical support and service in Russia.
