How to choose China IP camera factory

It is certainly that Shenzhen in China has become a manufacturing base for global video surveillance camera, but also the world's most centralized ip video camera manufacturers, Chinese is the country with the largest ip video camera actually owned manufacturers. According to statistics, all China security camera factory is over 2000, they can produce all kinds of surveillance ip video camera products more than 30 million units, but due to the low barriers to entry, now most of the China surveillance companies are SMEs, and the confusion in the market, product quality is uneven, particularly in most camera manufacturers are purchased by other companies network camera module, and then as simple as analog cameras assembled, the product is cheap, but the quality is not guaranteed. Therefore, we must consider the following items when selecting a China IP camera manufacturer


1. To know the strength of the network camera vendors

The users need to know the strength of China's surveillance manufacturer, supplier of relatively low barriers to entry industry, production of security products quality varies greatly, some supplier and therefore can not go on long-term development in the market, to users sale inconvenience, many customers complained that after the failure of HD IP CCTV camera, often even the suppliers are to be found. So, before you purchase, the supplier should have sufficient understanding.

At present, Chinese is divided into four kinds of IP camera suppliers:
 First: industry giants: Hikvision and Dahua, analog and digital front-end, back-end solution and all other IP CCTV products, well-known;

Second: focusing on IP video surveillance product development and production company: for example Sysvideo, Histream, Launch Digital etc;

Third, focusing on the development of IP CCTV cameras solution, do not produce the complete IP camera company : like Xiongmai and Topsee.

Fourth: traditional surveillance camera company, No researching team, these company,  before they assemble CCTV cameras, is now available from the IP network camera solutions provider IP network camera solution, then assembled, the prices are very cheap.


2. Does the China IP network camera company to provide the back-end video device and software

The user need to consider the compatibility of IP network cameras, it is best choice the company who can provide IP network cameras and network recorders , central management software, if you purchase IP network cameras and recorders from different suppliers  there may be incompatibility problems.


3. Checking China's IP network camera company service quality

Under normal circumstances, the difference with the level of company to produce high-definition IP network camera is not large, who can provide customers with more comprehensive services, who will be able to dominate the market. Before buying, users can often communicate with company and technical, will be able to fully understand the IP network camera factory service projects. It should be noted that,

For the manufacturer's warranty item must be knowing, avoid problems after-service cost is too high. In addition, many IP network cameras factory from analog camera company, they have no support software of excellence engineers, the service will be poor, a problem difficult to solve.

4. The network camera product price comprehensive comparison

Due to fierce market competition, many manufacturer in order to lower costs, it will save a lot of product testing aspects, they use the cheapest materials, although the price is very cheap, video quality looks no big difference, but relatively poor stability, after a very long term run to failure. So when customers select products, they can't choose the cheapest products.


5. Learn Chinese IP CCTV camera manufacturers established

As the IP CCTV camera products need to involve a lot of software development, must go through a long period of accumulation of experience, so through a company established time, you can judge their R & D experiences.

6. Does China IP camera manufacturer able to provide customized service

Many security products dealers like to use their own brand, they hope China IP CCTV camera supplier can provide customized service, because most China's suppliers don't have ability to develop IP CCTV cameras, and therefore can not provide customized development of hardware and software.

8. Understand the IP CCTV camera supplier location

At present Chinese's good IP CCTV camera factory concentrated in Shenzhen and Hangzhou, for example Hikvision and Dahua in Hangzhou, Sysvideo and Histream, Sunell,Launch in Shenzhen.

9. Asking Chinese's surveillance professional engineer

Chinese surveillance industry market is chaotic, to really understand a ip video camera factory , a better approach is to consult Chinese surveillance professionals or CCTV security Association, they are very clear to the actual situation of each supplier.

10. Select the matching IP CCTV cameras manufacturers

While the big factory,  such as Hikvision has a more comprehensive product line and greater strength of the factory, but does not mean it is your better partner. Due to the large company famous brand, and the price will be very public, the installer difficult to make good profits. And big companies have a fixed installer  in each country, other new company in order to distribute their products more difficult, and their sales policy is not flexible, it is difficult to obtain personalized services. In addition, not every product is the best. But like Sysvideo who focused on IP cameras and IP DVR / NVR products and other professional developers are more flexible, also can providing OEM/ODM customized service.
