Cable is widely used in security engineering. Both the CCTV TV monitoring, entrance control, anti-theft alarm, fire alarm, or public broadcasting, intelligent routing, remote meter reading and other kinds of systems cannot do without the cable act as a go-between. If the security system compared to the human body, wire and cable products then used in the security system is throughout the body's blood vessels and vessels, its importance is self-evident. Engineering maintenance experience has proved that the quality of the security cable for the protection of project quality, extend the life of the project is very important, therefore, users and engineers in the selection of cables when extra attention. Overall, the choice of security cables should be considered from the following five aspects:
Enterprise qualification and product quality inspection certificate
Users or engineers to buy security cables, the first thing you need to focus on is the enterprise and product qualification materials, need to understand the following categories of production enterprises qualification certificate:
1, business license, organization code certificate, tax registration certificate can indicate the scale of the production enterprise strength and enterprise grade.
2, the national industrial products production license (cable), CCC Chinese national mandatory product certification certificate, the Ministry of information industry, network card, ISO9001 certificate is the essential mark of production license qualification and the level of quality management of enterprises. Among them, in addition to ISO9001 certificate, several other types of certificates must have, and vice versa is illegal production or operation of products.
3, the national authorities within the validity of the quality inspection report, can fully prove that the production enterprise of the detected product manufacturing and quality control has reached the national standard.
4, other certificates or documents, such as industry membership certificate, honorary certificate, identification certificate, patent certificate, etc., are the production enterprises in the industry's user awareness, influence and overall strength of a strong proof.
Formal production enterprises with the comprehensive strength of enterprises, through and obtain various types of national certification, relevant qualifications complete. Enterprises in the daily production process, product quality is not regularly accepted by the state authorities supervision and inspection, quality and service are guaranteed. At the same time complete enterprise and product qualification is also security engineering acceptance must have conditions.
Two, cost and service
Users purchase security cable products, after the relevant qualifications of the production enterprises to understand and carefully examine the evidence, next to the performance and cost of products and services, and supply security ability of a comprehensive measure of the.
As contractors or direct users, in the hope that the product quality is not much difference between the inevitable conditions, maximize the use efficiency and value to the most reasonable price. Currently the security system engineering required a variety of specifications of the cable, the industry's mainstream security cable companies are generally able to be guaranteed. So some users one-sided praise of foreign brands, and high priced purchase of cable products consumption concept is irrational. Similarly, blindly pursuing low-cost, while ignoring the practice of product quality is not desirable. Should be fully aware that, in accordance with the law of market economy, reasonable price means reasonable quality assurance.
Homogenization of today's market products has become a trend of development, price differences are not obvious. Make product service becomes more important. Using the characteristics of engineering related products to the requirements of production enterprises to provide full service, from the field of construction and acceptance of system engineering design to project, from the system to ensure the normal operation of the day after the follow-up maintenance, design and construction process of the change of the individual needs of users and many other changes, need not only have the technology of production enterprises the corresponding power, need more rapid response and improve the service system. Therefore, stable and reliable product performance, reasonable price and improve the fast service security is an important part of the purchase of security cable products.
Three, manufacturers field trips
Users in the purchase of cable products, the size of the manufacturer and the production base of field trips is also very important. There is a saying goes "is seeing is believing". The special cable products determines the performance of the professional cable detection means, the user is used to determine the general quality of cables from the look and feel good, but the real technical performance and parameters have to rely on the professional cable testing equipments can be realized.
