Q:Home pinhole wireless surveillance camera where to sell? How much is the miniature camera?

It is clear that object-oriented is the function to divide the problem, not the steps. The same is the plotting of chessboards, which are scattered in the total number of steps in a process-oriented design, and it is likely that different versions will be drawn, since the designer will take a variety of simplifications in the light of the actual situation. And object-oriented design, the drawing may only appear in the board object, thus ensuring the unity of the drawing.

Q:How to install a camera at home, I can visit a website outside the home to monitor the situation?

First, through the browser login: enter the ip address and enter the user name password, you can monitor the camera's real-time picture

Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera? How far can its DC current output? Please have experienced master answer, thank you

Most of the time with seven infrared one machine, the nearest infrared machine 15 meters, farthest infrared one machine 110 meters. Cloth RVV2 * 1.5 power cord

Q:Monitor how the camera is connected

1. Monitoring camera is a professional video surveillance equipment, but the professional monitoring equipment is also necessary to connect the professional cable? Of course, only with a professional transmission cable to achieve the best results, but in the requirements of the quality is not necessarily a hundred points with the network cable can also monitor the transmission of video, then how to use the network cable connection monitoring camera? This article will be for how to use the network cable to connect the surveillance camera and the network cable to connect some of the advantages of the camera to do a simple introduction for your reference. How to use the network cable to connect the surveillance camera wiring convenience, cable utilization is high. An ordinary super five cable, there are four pairs of twisted pair, you can simultaneously transmit 4 video signals, or 3 video, 1 control signal; and cable lay better than coaxial cable laying.

Q:Now the surveillance camera really tmd nonsense, four hundred or five hundred products with more than a hundred USB camera are not as good as poor resolution did not shadow, and generally are so, monitoring products are pit father,

Almost no static power consumption. This makes CMOS power consumption is only about 1/3 of the ordinary CCD, CMOS important problem is in dealing with fast conversion of the image, because the current conversion is too frequent and overheating.

Q:Monitoring camera POE power supply is good, or centralized power supply good?

If you have to use (see profits, you understand), it is recommended to choose some big brands of products, such as Huawei, 3com, etc., the cost is high, 20 meters if the use of oxygen-free copper feet .5 super five twisted pair , The loss on the wire can be ignored, but the use of POE power supply to consider the lightning ah, a break is a big string ah! :) POE to be used to do lightning protection measures Oh. And POE power supply in the event of failure when the investigation than the use of some trouble with the transformer.

Q:Monitor the camera why the black screen?

Fifth, the control camera control equipment, such as DVR / NVR / capture card, check its related software is running properly, whether the latest version, if not suggested to contact the manufacturer to upgrade the software can be.

Q:Is the camera pixel taller the better?

But because of the current network bandwidth limitations, really very high physical pixels in the video screen may be cards, depending on your network. Now most of the camera on the market is 30W physical pixels, said hundreds of millions are blowing, a few can reach 130W physical pixels, but expensive, Logitech is currently the highest pixel is only 200W, so 800W, 500W those are Is interpolated, there is no practical significance.

Q:Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it

1/4 and 1/3 refer to the size of the camera's sensor chip. The camera image sensor (CCD or CMOS) has an area of 1/3 inch or 1/4 inch. The same manufacturing process and standards, the larger the image sensor (CCD or CMOS) area, the better the image quality (resolution).

Q:How to install a surveillance camera

4. Switch to the video settings, wait a few seconds after you should see the video screen, display the video device to start successfully, and you can see the screen.
