The development of modern technologies has led to the emergence of new technologies. The first of these concerned the introduction of human security and their lives, safety of property, etc. One of these technical solutions become video camera surveillance. Since the beginning of use, they repeatedly modified and gained many new useful and specific function. The main function performed by surveillance cameras – to send images (subject matter) to a means of information output (monitor) in real time.

One of the main elements of the camera matrix, because of its quality depends on the quality of transmitted images. Camcorders observations are divided into subtypes on the following parameters: – Power supply (220 V, 12) – picture (color, black and white) – how to install (domestic, street) – sensitivity – the mechanism of attachment (static, turning) – size – and others, depending on the objectives, surveillance cameras are divided into: – Open-frame camera – can be installed in any piece of furniture and used for covert surveillance – miniature video cameras. Are small. Can be both static and rotary – hidden camera – the most compact cameras – surveillance cameras standard design – supplied without lenses, which are chosen depending on requirements and locations of the proposed installation. If necessary, equipped with additional means of protection – covers (when installed on the street or in a production shop) – IP-video cameras – have access to the local network and the network – Internet; – dome cameras – mounted on the ceiling, are unmanaged, and robotic – hull camcorder – Managed camcorder – infrared camera; – Vandal-proof camera surveillance. If you are installing surveillance cameras to consider the viewing angle, focus, illumination. Since the camcorder is a component of video surveillance requires accurate calculation of the number of required cameras, lighting and rendering required additional hardware (shrouds, etc.

Filtration Systems

Comments Off on Filtration Systems

Reliability and durability of systems to deliver fluids, as well as other hydraulic systems depends largely on the correspondence of clean oil to the established norms. Oil can pollute both mechanical inclusions, dirt and decay products, and formed water and gases. Usually recommended to maintain the level of water absorption of up to 45%. In order to promptly determine whether treatment has developed various hydraulic sensors, including sensors determine the water content in oil pressure switches, etc. With their help staff to receive information about the state of hydraulic oils, and can take on the need to clean up. Removal of off-line mode in hydraulic systems can be produced using various filtering systems – portable, ie portable, mobile – usually on a mobile platform and fixed, embedded in the hydraulic system itself.

Each of these has advantages and disadvantages. Laptops can easily be moved due to its light weight, mobile systems are more high, but take up more space and the cost is higher. Embedded systems allow you to filter automatically, permanently maintaining the required cleanliness level of oil, which is particularly important for such hydraulic systems such as lubrication of bearings turbine power plants. Some filtration systems are equipped with control equipment, automatic control, heat-exchange devices to provide the necessary cooling properties of hydraulic oils. Ion-exchange unit can restore the acid number, thereby stopping the aging process oil. So , the choice of a specific type and model of the filtration system must be carried out with appropriate cleaning performance, its periodicity, Filtration, and have some reserve capacity. However, it is necessary to avoid obvious overcapacity filtering, as this will cause undue financial burden.
