Brand choice
At present, on the market, domestic and foreign surveillance camera manufacturers can be said to be a surging storm, enjoying themselves. Whether it is imported Samsung, Sony. Or domestic Datang, Haikang and so on. They are all working hard to market their products in batches. This phenomenon has undoubtedly brought consumers more extensive choices. Compared with domestic brands, the advantages of imported brands are advanced technology, stable use of performance, excellent structural design, and so on. Of course, the inconvenience of expensive prices and after-sales service has also become a burden that people have to face when enjoying advanced equipment.
For domestic brands, in addition to the convenience of after-sales service, the richness of price choice is one of the reasons favored by people. More "people-friendly" prices undoubtedly bring more choices to users. However, one thing to note is that compared to imported brands, the phenomenon of virtual branding of domestic brands is obviously much more serious. Here, the editors are not blindly superstitious about the quality of imported brands, but the status quo involving inconsistent parameters and performance is left behind by currently imperfect industry standards. Therefore, in the purchase of low-priced domestic surveillance cameras, we must pay more attention to the actual performance testing.
PTZ performance inspection
During the work process of the high-speed dome camera, the fast head can be said to be the core component of the entire machine. Its reliability directly determines the stability and performance of high-speed cameras during use. The biggest feature of the high-speed ball and uniform ball is also the high flexibility of the PTZ. At present, the main indicators to measure the quality of PTZ include the rotation mode, the limit (maximum/small) speed and so on. Through the actual observation of these indicators, you can effectively understand the actual performance of high-speed domes. In addition. In the case that the image is placed at the maximum, controlling the speed of the PTZ exchange, and performing an instant stop experiment, it can effectively predict whether the PTZ will be shaken at work.
Selection of camera multiples
Under normal circumstances, the imaging magnification of the camera is also one of the main indicators that people are very concerned about. At present, the integrated intelligent high-speed cameras on the market are dazzling, and the marked multiples are also nuanced, and even the hype. Variety of technology variations are presented to users, and consumers are easily lost in front of these data. Here, the editor should remind you that the main performance that can affect the camera's distance is its optical zoom capability. In some cases, the telephoto capability of a high-power integrated camera may not necessarily be better than that of an ordinary camera with a low-variable optical level, because the electronic zoom capability contained in the total multiple is mostly under the condition of reducing the image clarity. Amplification processing does not greatly improve the actual effect of monitoring.
Camera compatibility options
In the high-speed ball surveillance camera, the only connection channel with the external control system is the decoder. However, this is also a part that many users easily overlook. Therefore, in the selection of a high-speed dome camera, it is also very important to understand the network protocol suitable for the decoder and to be able to select the device that matches it. Otherwise, it will bring great trouble for the control of the monitoring work. At present, many fast dome cameras with multi-protocol integration have been introduced on the market. The editor thinks that if there are qualified users, they can choose such devices to enrich their systems. After all, the rich compatibility effect is very helpful for the future improvement and expansion of the system.
The choice of camera movement
In general, high-speed dome cameras have a very high level of intelligence. Therefore, the matching function of the movement is also very important. Including its variable power, focusing effect, minimum illumination, infrared sensitivity, automatic color to black and so on. Otherwise, it is easy to form a bottleneck in monitoring work at the front end of the surveillance camera. Of course, the different needs of different cameras must be matched according to their respective environments, so we will not repeat them here.
In addition, the functions of the menu, ease of use, control methods, after-sales quality, and anti-riot capabilities all require reasonable consideration of the environment.
Today, there are more and more devices that can be monitored on the market, and the content of technology, including functions, is also growing. However, if we proceed from the most essential functions and environmental characteristics of surveillance cameras, we can still screen out a large number of options. Therefore, to master the important performance of a surveillance camera, you will eventually choose the most suitable high-speed dome camera.
Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion resistance. It is an alloy steel that does not rust easily, but not absolutely. Stainless steel plate refers to the corrosion resistance of weak medium such as atmosphere, steam and water steel plate, and acid resistant steel plate refers to the corrosion resistance of chemical etched medium such as acid, alkali, salt steel plate.
According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic biphase stainless steel plate and so on four categories? According to the main chemical composition of the steel plate or some characteristic elements in the steel plate to be classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. According to the performance characteristics and use of steel plate classification, is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate. Currently, the commonly used classification method is according to the structural characteristics of steel plate and steel plate chemical composition characteristics and the combination of the two methods. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening type stainless steel plate or divided into chromium stainless steel plate and nickel stainless steel plate two categories.
Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipelines, coastal area building external materials, etc.
