Integrated camera purchase five major issues

The purchase of integrated cameras is not particularly different from that of ordinary cameras such as cameras, dome cameras, infrared cameras, etc. However, because of the integrated design, more factors are selected and more complex. Digital China digital video surveillance experts remind everyone that the choice of integrated camera requires five major factors.

First, the quality of the lens and DSP technology China's current surveillance camera lens and DSP are basically imported technology, which the camera was Canon, sony occupy more than half of the country. Shenzhou Digital Ampon also pointed out that there are also many excellent camera manufacturers in China, each with their own technical advantages. When users purchase, they can also make a careful judgment.

Specific to the choice of lens, the lens of the integrated camera is related to zooming and focusing. The common zoom camera on the market is divided according to the focal length of the lens, ie, the value of f, which is 22 times and 27 times, which is the optical magnification, that is, The true magnification of the camera. However, in order to increase the number of gimmicks, many merchants have added the magnification of the camera lens to the electronic magnification and become cameras such as "220 times", "270 times" or even 300 times or more. China Digital Ampon reminds everyone that when purchasing a variable-speed integrated camera, do not be confused by the so-called variable magnification. The mainstream magnification is only 22, 27, and 30 times. Select according to your actual needs and applicability. The right lens, not blindly believe in the parameters advertised by the business.

The automatic zoom camera is mainly used in an unattended environment, and the manual zooming is not particularly used for monitoring points, and it needs to be manually debugged to complete the monitoring. In addition, when selecting a surveillance camera, not only the integrated camera but also other cameras such as camera, dome camera and infrared camera, etc.; must be actually tested to understand the true performance of the lens.

Second, the stability of the camera motor Motor quality is a crucial factor in determining the quality of the camera. Compared with synchronous motor, DC motor performance is more excellent, but the price is relatively expensive, the same corresponding long service life, under normal circumstances, the choice of a DC motor camera life can reach five to ten years. However, many cameras on the market, such as cameras, dome cameras, infrared cameras, etc., generally use synchronous motors, which creates many problems. For example, the power of the synchronous motor is relatively large, and the camera is exposed to severe heat generation during operation. The heat output is large, and the camera is prone to burn out during prolonged use. Therefore, when selecting an integrated camera, it is possible to tilt the DC motor as much as possible if conditions and funds permit.

Third, camera compatibility Camera compatibility refers to the camera for multi-protocol support. Since China's surveillance market is now in the transition period of analog-to-digital conversion, different products support different protocols in the market where products at different stages of technological development appear at the same time. This can easily lead to incompatibility of surveillance systems. Therefore, a good camera is not only an integrated camera, but also includes a camera, a dome camera, an infrared camera, etc. It should have strong adaptability to different monitoring systems. That is, it supports multiple protocols and can handle various standards of video. Streaming, after the user purchases such a camera, he can not worry too much about the camera's incompatibility and the scope of application is more extensive and convenient.

Fourth, the camera's interface and scalability of the camera should have good scalability, dedicated interface to facilitate its intelligent digital upgrade, easy access to the monitoring network, rather than an island, from beginning to end Can only have specific features. The expandable camera will have greater flexibility and applicability in use and should be the user's first choice.

5. Waterproof and explosion-proof design of cameras We must not underestimate the waterproof explosion-proof enclosure design of the camera. In outdoor application environments, good waterproof and explosion-proof cameras can ensure the extension of the camera from several times to several tens of times, and the cost-effectiveness brought by the camera is very intuitive. . For a camera with a good water-proof and explosion-proof design, the general housing cost is relatively high, and the production process is also more complicated. When users purchase, they must make appropriate choices according to their own scope of use. Do not ignore this factor. .
