Q: What line is the security monitoring power line?: Note that copper wire is twisted, RVV2 two wire within *1.0 or 2, that is the line diameter, line size according to the case design and calculate the size of the load current, decided to use much of the wire diameter.

Q: Our company is a trading company, the main security monitoring products, but not simple sales, in fact, but also for customer design, installation, debugging to collect. The costs involved are: 1, do the server with the computer (6000 yuan), 2 meters (2900 yuan) 3, all kinds of materials, accessories and so on 4 installation staff wages, travel expenses (field installation) and so on, ask you master, this situation should be used and what subjects to cost? How is the carrying cost? How about the entries? All the scores are presented.: If the purchase of security monitoring equipment for the sale of commercial enterprises, it should be used as inventory merchandise accounting, sales costs included in the main business costs or other business costs.Borrow: main business call / other business cost

Q: What are the most profitable products in the security industry?: Introduction of the most profitable products in security industry1. system integration, including software and hardware. System integration is a powerful company, in this case, describe the extent of its profits, and then a project to live three years. That is, a company that provides solutions.2., there are wireless alarm products, the market is broad, high degree of customer acceptance, you can make the cost recovery in three months, you can enter a high return within a year.

Q: How do security control engineers get it?: Security system integration engineers and security system integration project manager, students complete the course, by the Ministry of information industry electronic Talent Exchange Center awarded the national information security system integration project "engineer" technical certificate and the Ministry of human resources and social security issued by the "653 project" "security system integration engineer security system integration project manager certificate". Certificates can be used as an important basis for professional technicians to employ, hold, grade and promote their positions. Certificate holders will be included in the national information engineer talent pool for enterprises and institutions website inquiries.

Q: What are the functions of security decoder, the main function and principle?: The device that controls these actions is called a cloud mirror controller, also called a decoder. Coupled with the control keyboard control device can control the servo device more, with the monitor consists of a simple monitoring system. With the development of. Decoder can be placed inside the pan (built-in decoder), and control equipment interface is generally RS-485, the commonly used communication protocols are: PELCO-D, PELCO-P, AD/AB, YAAN and so on.

Q: Monitoring security in the scope of individual business, how to write?: Engineering: building intelligent security system, integrated wiring, sales: security equipment and accessories, if you want to write specific points also line, such as cameras, video recorders, and so on

Q: What projects does security monitoring mean?: Security monitoring refers to the building intelligent system equipment installation project commonly used building intercom, infrared radiation, video real-time monitoring, and real-time alarm system.

Q: What's the outlook of the security industry?: Surveillance lens and storage developmentSurveillance camera seriesAnalog technology video camera of the 70-80: transistor technology, camera, resolution of about 480 lines, basically no digital technology;Analog technology in 80-90, solid chip camera: CCDCMOS camera, the initial resolution of about 380 lines, gradually increased to 510 lines;90-00's IP digital camera with video server: early video encoding for the IP signal, the subsequent development of IP camera based on IP technology, the total number of pixels is about 300 thousand - 450 thousand, equivalent to about 480 line camera.00-10 HD applications: HD IP cameras, based on high-density CCD technology. The total prime number is about 1 million 300 thousand - 2 million;10- digital analysis technology: ultra high definition IP camera, embedded into video analysis, with early warning function, face recognition, object position identification and other digital security cameras;

Q: Do you have a safety monitoring system?: Security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and from the camera to the image display and recording to form an independent and complete system. It can reflect the monitored object in real time, image and reality. It can replace the manual for long time monitoring in bad environment, and record it by video recorder. At the same time, the alarm system equipment for illegal invasion alarm.
