Q: What data does security monitoring and bidding require?: (4) the copy of the legal person's power of attorney and identity card of the bidder;(5) the principal agent and after-sale service certificate of the main equipment;(6) information about the tenderer's profile;(7) part of the list of users in recent years.Note: all photocopies of the above documents should be stamped with the official seal of the unit, and the tenderee shall keep it.

Q: What categories of security assets is the security monitoring system?: According to the above classification: housing, buildings, machinery, equipment, transport equipment, electronic equipment, and so on. Therefore, the security monitoring system belongs to the electronic equipment!

Q: Intelligent security and smart home profit space which big?: The security monitoring system, according to the different functions of system components, the whole security monitoring system is divided into seven layers: presentation layer, control layer, processing layer, transport layer, execution layer, support layer, data acquisition layer. Of course, because of the increasing integration of devices, for some systems, some devices may exist in the system at the same time as multiple layers.

Q: How many lines are there in the security monitoring system?: You can't control the camera lens, only video cable and power line，If the camera does not rotate, just two linesVideo cable and power cordAdd signal control line if rotating

Q: How to monitor project quotation, including materials, auxiliary, artificial, installation fee! How to report, seek advice from the industry!: Finally, there's the tax, you didn't add itIf you think the profit is low, each can be adjusted accordingly, of course, the most standardized is in accordance with the fixed rate reported, fixed quote, then other costs should be added at about 40-50% of equipment costs.

Q: Begged, "security monitoring" for the record, where do you need to go? What materials need to be prepared?: (four) system selection of equipment, equipment type, type, quantity;(five) the main equipment, equipment, wire production registration, approval certificate or safety (3C) certification or production license and inspection report selected by the system;

Q: What are the main components of the global security system?: (8) perimeter alarm system;(9) elevator five party alarm system;(10) centralized management system for keysFrom the classification dependency relationship:Video surveillance subsystem;Alarm subsystem;Guard patrol system;Voice intercom subsystem;Audio-visual broadcast subsystem;Intelligent analysis subsystem;Perimeter guard subsystem;Location and tracking subsystem;Power environment monitoring subsystemFor security system, according to the different functions of the system, we divide the whole security monitoring system into seven layers - presentation layer, control layer, processing layer, transport layer, execution layer, support layer and acquisition layer. Of course, because of the increasing integration of devices, for some systems, some devices may exist in the system at the same time as multiple layers.1. presentation layerThe presentation layer is the most intuitive, and it shows the quality of the whole security monitoring system. Such as surveillance TV wall, monitor, treble alarm horn, alarm, automatic answering telephone and so on, all belong to this layer.

Q: What is the front end product of security?: The front part of the finger detection signal input devices, such as camera, microphone and so on, so it is not difficult to understand what is the end product.

Q: What is the future of the securities industry?: Foresight network released the "China security industry market foresight and investment strategy planning analysis report" data show that in 2011, China's security industry market size reached 269 billion 600 million yuan, an increase of 19.82% compared to the previous year. From 2006 to 2011, the security industry market size increased from 120 billion yuan to 269 billion 600 million yuan, a CAGR of 17.61%, to consider the risk of future uncertainty, a conservative estimate of 15% as the next 5 years the lowest growth rate of composite.In fact, after 2011, Ping An China construction into the overall promotion stage, the overall investment of nearly billion, the industry will enter the peak of construction in the "12th Five-Year" period, all segments due to the early market penetration, market demand is expected over the next 5 years will show different growth rate of 20%-80%, the overall annual growth rate will remain at 20% about 20% growth rate as the next 5 years the highest growth rate of composite.

Q: Do you have any security monitoring system with you?: It can be monitored by mobile phone app, or monitored by security monitoring handheld terminal equipment.
