Q:Who knows security monitoring common faults and solutions?
Can first separate the monitoring system, 1 first check the front-end equipment, with engineering treasure to connect the camera, there is no ripple, not in the use of monitoring power supply project, treasure access surveillance video. If there is no front end, no problem. After processing the back end, insert the rear video line directly into the engineering treasure video, if not, that is the problem on the hard disk video recorder, if you have one. That's the transmission part. The transmission section can see whether the video lines have power jamming devices, powerful electric power, signal communication towers and so on. Some words can be wire principle interference source or install galvanized tube, reduce electromagnetic interference, or use video anti-interference device and so on.
Q:Every day, mainly engaged in monitoring and installation, there are other security products
Hello, my friend:What's the future? What's the future? I think we can make money as long as we can earn it
Q:Enterprise security monitoring workflow
Enterprise rules and regulations should be based on specific circumstances, and generally have administrative, sales, technical department, engineering department, the specific rules and regulations of each branch.
Q:How does the security monitoring system go through the line?
N groove transition, the interface should not be burr, groove transition to smooth.N line pipe over two elbows must be left in the distribution box.N wall socket should be installed from the ground 30 cm above the bottom box and other remained high, parallel.N line pipe adopts galvanized thin-wall steel tube or PVC
Q:How is the security monitoring cost charged?
1. buy computer ah meter materials are purchased when stock commodity or raw materials and related subjects, staff wages and travel expenses and other expenses included in expenses for the period (management fees, sales expenses and financial expenses) etc... As for the end of the period, you need to transfer the cost, the main transfer period expenses, the main business tax and additional, income tax and other subjects.2., the specific entries are: Borrow: main business costs;Credit: business taxes and surchargesManagement expensesFinancial expensesSelling expensesIncome tax
Q:What line is the security monitoring power line?
Standard monitoring power line, AC DC common RVV2*1.0, RVV2*2.0.....RVV is copper core PVC insulated, PVC sheathed cable,
Q:What industry does security belong to?
The security system is defined in the domestic standard as security & protection system (SPS), while abroad is more called prevention Crime (Loss prevention & a). Loss prevention is the task of security industry, and crime prevention is the responsibility of police law enforcement departments.

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:Security monitoring project is not to build the division of electromechanical professional practice
Relatively speaking, in addition to building the largest number of candidates, the municipal public and mechanical and electrical professional demand is also large, but also anchored higher than the price of construction.
Q:Does it require 3C and other certifications to produce wires for sensors such as security, surveillance, medical and electronic sensors?
3C certification must be done, and other certifications can be done. What are not specified, then you need to do is wire into the private letter ah
