Q:Ask the professional to answer, monitor the camera with water ripples

To distinguish between power problems and ground loop problems, an easy way is to control the host, the nearest access to a power supply without a problem camera output signal, if the monitor does not appear on the interference phenomenon , Then the control host no problem. Next, you can use a portable monitor near the video output of the front-end camera, and check each camera one by one. If so, then processed. If no, the interference is caused by ground loops and other reasons.

Q:What are the problems with the surveillance camera?

Wait for you to meet the situation to say it again, I give you answer, you ask the question is like to buy a mobile phone, mobile phone will generally what the same problem. People are so depressed! The The Surveillance cameras, Dongguan Le Pu Electronic Technology Co., Ltd., this is very good!

Q:20 meters away with the number of mm monitor camera lens appropriate?

At the same time, the same focal length, length and width shooting range also with the camera CCD has a relationship. Charge - coupled Device, Charge - coupled Device. It is a semiconductor device that converts optical images into electrical signals. At present, most of the CCD chip used in the surveillance camera is 1/3 "and 1/4", that is, the target size is 1/3 inch and 1/4 inch. CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity.

Q:What is the difference between monitoring the camera and the usual?

4.BNC interface: that is, coaxial cable connector. Can cut off the video input signal, so that the interference between the interference reduction, and the signal bandwidth, can achieve the best signal response.

Q:Monitor the camera when shooting white, is the kind of white, basically do not see the image, and exposure like

The image is not adjusted, there may be two reasons, the first aperture is too large, the exposure is too high; the second brightness is too high, the best brightness, saturation, contrast recovery under the default.

Q:What is the meaning of monitoring the focal length in the camera?

Surveillance cameras sellers do not understand the concept of a lot of focus, they tell you that the lens is a few millimeters, the a few millimeters is the focal length or lens caliber they do not understand, they only know to see far or see close.

Q:Home wireless surveillance camera price, how much money?

Home monitoring equipment is a co-ordination concept, because at this stage of China's domestic monitoring equipment without a clear distinction, the traditional analog monitoring system can also be used as a home monitoring equipment; now high-definition wireless network camera can also be used as a home monitoring equipment. Therefore, for different monitoring systems, the price of its home monitoring equipment is not the same.

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:What is the meaning of the high definition and standard definition of the surveillance camera?

If the application in the video surveillance, according to the specific monitoring target to select the camera standard, high-definition camera video files generated by the large, the need for large-capacity storage media, of course, if the monitoring is relatively static target selection standard is enough , If it is to monitor the dynamic target that will consider the high-definition camera, or when the screen playback can not see the characteristics of moving targets. Specific issues specific treatment.

Q:HD camera and infrared camera difference

HD camera is said that his clarity, infrared camera is that it's night vision function, in order to highlight the main features of the name of a
