Q:Security engineer and security system integration engineer
Security engineer is a broad range of security engineers, the main responsibility for:1. Assist project manager to implement and manage the project site;2. Assist senior designers in project design;3. Assist project manager to coordinate and manage external employment service or construction team;4. Manage the material on site and assist in emergency material purchasing;5 、 responsible for timely feedback of product problems and system problems during construction.
Q:Security monitoring.The security monitoring platform often appear. How to deal with the phenomenon?
You say. In replays? If so, then your video settings are set to motion detection, and you go to the video settings instead of the timer settings.
Q:What projects does security monitoring mean?
Hello, security monitoring belongs to weak current project.A simple monitoring device includes: Camera + power + direct + video line + hard disk recorder + hard disk + monitor
Q:Who knows security monitoring common faults and solutions?
It's OK to divide the equipment into cards. For example, the back of the surveillance system has a ripple of water
Q:Security monitoring, construction costs, how much is reasonable?
Usually in accordance with the 20% collection, according to the construction of the difficulty can be a certain coefficient.However, such a small project like you, if in full accordance with the proportion, not your loss is the loss of Party AIt's better to negotiate a reasonable cost
Q:What are the main components of the global security system?
The control layer is the core of the whole security monitoring system, and it is the most clear embodiment of the system's scientific and technological level. Usually we have two control modes analog control and digital control. The simulation control method in the early stage, the console is composed of controller or analog control matrix, which is suitable for small local security monitoring system, this control method has lower cost, the failure rate is large but for some security monitoring system, it becomes too complicated operation and no price advantage, then we it should be the choice of digital control. Digital control is the industrial computer as the control core of the monitoring system, it will complex analog control operation into a simple mouse click operation, the huge analog controller stack shrunk into a computer, control cable will be complex and huge number into a serial line. It can change remote monitoring into reality and provide possibility for Internet remote monitoring. But digital control is not so perfect, the price of the control host is very expensive, the waste of modules, the system may collapse, the crisis is still lagging behind and so on.3. treatment layerThe processing layer may be referred to as the audio and video processing layer, which will have the audio video signals sent by the transport layer to be allocated, enlarged, segmented, and so on, and organically connect the presentation layer to the control layer. Audio and Video Splitter, audio and video amplifier, video splitter, audio and video switcher and so on, all belong to this layer.
Q:What is the future of the securities industry?
Foresight network data monitoring center shows that in 2012 China's security market is the lowest 310 billion yuan, while the highest will reach 323 billion 500 million yuan. By 2015, China's security market size is the lowest, 471 billion 500 million yuan, the highest will reach 559 billion yuan.Prospective network security industry research team believes that promoting the use of multiple factors civilian needs and market demand in the safe city construction, industry, security industry will usher in a period of rapid development, the continued expansion of the security market will bring rapid development opportunity.I hope my answer can help you.
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: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:Will security monitoring work be dangerous?
Monitoring the construction of the project requires constant contact with alternating current;Power tools are required;
