Q:Monitor the camera mentioned in the three stream, what is the meaning of ah, which three?

Three streams of intelligent network transmission H.264 stream, dynamically adapt to ADSL network bandwidth and changes, the audio is always smooth, the video is always perfect, it will not be malicious to seize ADSL bandwidth, such as download, chat and browse the web needs of the bandwidth. Rogue network applications and software is the network operators and national security departments to crack down on the object.

Q:Monitoring camera 6mm 8mm 12mm 16mm length and width can be according to how much.

3.6MM10-20 meters 6MM20--35 meters 8MM30--50 meters 12MM40--60 meters 16MM50--70 meters General project is: the target in the display device is greater than or equal to 1/6 of the area, you can see the target.

Q:Monitor the camera what is the zoom

The lens is equivalent to the human eye lens, if there is no lens, the human eye can not see any objects; if there is no lens, then the camera output image is a vast expanse of white, no clear image output, which with our home camera and camera principle Is consistent. When the human eye can not stretch the lens to the normal position, that is, people often say myopia, the front of the scene becomes blurred; camera and lens with a similar phenomenon, when the image becomes unclear , You can adjust the camera's back focus, change the CCD chip and the lens reference plane distance (equivalent to adjust the position of the human eye lens), you can blur the image becomes clear. Thus, the role of the lens in the closed-circuit monitoring system is very important. Engineering designers and construction workers should often deal with the lens: the designer according to object distance, imaging size calculation lens focal length, the construction staff often on-site commissioning, part of the lens is to adjust to the best condition.

Q:Monitor inside the infrared network camera infrared light automatically switch and synchronous switch What does this mean?

Automatic switching --- through the image sensor to detect the ambient brightness, in the scheduled ambient brightness switch image color mode. The The The

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,

of. The current generated by these two complementary effects can be recorded and interpreted by the processing chip as an image. CMOS CCD for the most important advantage is very power. Unlike the diode composed of CCD, CMOS circuit

Q:Monitor the camera feel infrared

There are two kinds of camera lens: one is a CCD is a sense of the infrared are infrared (day and night type) lens and color lens sense of infrared lens

Q:Ready to engage in a facade ... to help people engage in monitoring. General how much of this type of profit. How to charge.

The current monitoring market is chaotic, the brand is more, at the same time, is also based on the current market demand is growing, relative to the three-tier cities in terms of profit margins can also be generally about 30% of profits, which refers to equipment sales, But do the project said, do relationship, you can control the profit margin, how much the general decision. Fees are not fixed, the construction fee is generally added in the profit after the total equipment to take 10% -15%.

Q:Digital surveillance camera how to increase? Each head of the ip are 192.168.1.10 now have ten cameras. Ask how to do?

With the computer IE browser input camera corresponding to the IP address, (computer IP network segment and the camera to modify to a network of Oh, that is, the computer IP is 192.168.1.xxx after the three and the camera does not repeat the IP like)

Q:There is a surveillance camera, want to adjust the location, hand touch the head, even live, do not know how the matter

Generally the case is the reason for static electricity, in theory, if your camera is using a transformer, that is DC power supply, then basically can be excluded from the leakage caused by the low-voltage (DC12V) camera, if There is a strong power into the words, then the camera will not be able to use, and here to note is not only the camera will have static electricity on your own may also have static electricity, you may say the same two cameras have a One is not, but you have to know the principle of electrostatic discharge, only when you come into contact with the conductive body when the static electricity can be released, you will have the feeling of Ma. In fact, if the camera is used properly, you do not have to worry about whether it is with static electricity, if you really worry, you can ground the camera, the general ceiling has a fire pipe and bridge, you can choose them to ground.

Q:Monitor camera lens 4-6-8-12-16MM difference.

These numbers on the lens label refer to the focal length of the lens. The larger the value, the farther the distance the lens can reach, but the angle becomes smaller.
