The first step: Determine the guarding range according to room conditions:
The balcony and door are the most vulnerable to invasion; secondly is the kitchen, den windows (kitchen and study are normally empty especially during nights so they are easy to be invaded by thieves); thirdly the children room and bathroom;
Here, we have a pretty good idea of the area that need to be guarded against, and also finalized the primary and secondary prevention of the area.
Step two: Determine the zones and the precautionary approach and equipment of each zone
After determining the locations and parts that are easy to be invaded you should decide the number of fortified points according to your surroundings, residential security measures, family environment, and other factors, as well as the economic situation.
Recommendation: The economic configuration
If the door and windows of the front door, study or kitchen are open or forced open or even sash shifted more than 1 cm, or any human enters the bedroom and living room under security state the corresponding detector will trigger the alarm, so that after the host machine receives the alarm signal and open the treble alarm simultaneously it will trigger phone telephone dialing alarm for owners, neighbors and pre-set phones.
Host is the heart of the system, all the other devices must be connected with the host, which receives your control operation through the keyboard or the multimedia software in the computer, then to control other devices to achieve it, for example: the cradle head rotation, the lens zoom, focus, the change of aperture. It also can transfer the camera screen you selected on the monitor you want to display, and make these different camera screens be displayed in order, each camera shows a time. Thinking about the system expansion and the redundancy of upgrades, used the video and audio matrix switcher, the number of channel of the video input should be larger than the actual needs, with RS-232 and RS-485 communication interface, can be arbitrarily connected with the keyboard master, keyboard sub-control machine, multimedia master,multimedia sub-control machine.
Decoders is the “translation” for the host and the front-end equipment, it translates the action command send by the host into the drive voltage and power that cradle head rotation, shot change requires for. To drive corresponding camera, electric three variable lens, indoor cradle head to complete a variety of actions.
The security center is the nerve center of the whole security system, it does not allow non-duty officer enter into by they want, and once a major case occurred, the security center staffs would be attacked firstly, so installed a video intercom system in the front of the security center. If someone wanted to enter the security center, he must press the doorbell to inform the duty officer, the duty officer observed indoor and confirmed, as soon as the switch is pressed , the door would automatically open. This will not only ensure the life safety of the duty officer, but also avoid the unnecessary interference from the outside world.
The security industry is irreplaceable. It has a role in promoting the whole community with the monitoring equipment continues to update. Monitoring equipment develops in a variety of forms; the development of the industry has an extremely important significance in our lives, showing more results in our life. From Network DVR to the NVR, digitized society will soon replace analog products. Many industries can not depart from the security monitoring, its use can reduce production inputs, and to provide better facilities for life. Security monitoring industry has made a significant change for social development; monitoring equipment will play a major role on the development of social, and has a remarkable sense of life. Since monitoring equipment appeared, district, shopping malls and parks have good security precautions to ensure the people’s living standards. After a long period of hard work and development, the major company’s products are increasingly mature and bring great convenience to our lives. Based on the improvement of people’s living standard, HD monitoring equipment intelligent is going to the world to bring a better development for our society. Rational using security monitoring equipment can bring prosperity and stability to our society. Maybe you can find the equipement like hidden camera in dhgate reviews.
The security monitoring camera can be divided into black and white color, because the monochrome camera has high-resolution, low-light advantages, especially can image infrared light, among TV monitoring system, the black and white CCD camera still has a higher market share. By the way,
Wholesale online is a good way of buying CCTV system. The camera listed in the CCTV security surveillance equipments list are usually without lens (except integrated camera), so in the practical applications, we need choose the appropriate lens for the camera based on the actual environment of monitoring site and the user’s requirement.
The use of spy cameras is very simple, usually as long as the lens is properly installed, connected with signal cables, power, it can immediately work.
When installing the lens, you need remove the protective cover of the camera and lens firstly, then gently rotating the lens into the camera lens interface and placing. Read more
“technology is the first productive forces”. It is not only able to promote the steady development of enterprises, but also can accelerate the pace of the social progress. With the constant improvement of technology, it promotes the development of security monitoring equipment market, wether a technology is mature or not, must be sure through the practical application of the products, it determines the pace of market development and the fate of the products. The video surveillance is the most critical part of spy cameras.
In order to meet the “HD” requirement of users, and solve the environment interference problem, the surveillance camera with low-light monitoring function has emerged. The low-light technology is a way to measure the sensitivity of camera, let the camera catch useful image information in the dark light or black days. The low-light surveillance camera does not need infrared lamp to assist in monitoring, it “fill light” by the filter, it retains the useful infrared lamp while filters the unwanted infrared, so that it can form a clear image at night. Although the low-light monitoring principle was not complicated, its birth solved the drawbacks of monitoring in the light, at the same time has made a contribution to the realization of high-definition monitor.
