Q:What is the difference between a camera and a monitor?

Camera digital camera The wide range of cameras, the basic principles of its work are the same: the optical image signal into electrical signals, in order to facilitate storage or transmission. When we shoot an object, the light reflected on the object is collected by the camera lens, focusing it on the light receiving surface of the camera (such as the target surface of the camera tube), and then through the imaging device to light into electricity, that is, "Video signal". Photoelectric signal is very weak, need to be pre-amplifier circuit to enlarge, and then through a variety of circuits for processing and adjustment, the final standard signal can be sent to the recorder and other recording media recorded, or spread through the transmission system or sent to the monitor display.

Q:How does the surveillance camera solve the backlight problem?

Second, always use the corresponding function of the camera, improve the backlit appearance. There are two kinds of cameras inside the security camera can be better to deal with the problem of camera backlight, one is a backlight compensation function of the camera, one is wide dynamic camera. Backlight compensation, also known as backlight compensation, is the screen dividends of several different areas, each area from the exposure. In some applications, the field of view can contain a very bright area, and the subject is included in the bright field surrounded by a picture of a bleak, no level. At this point because the AGC detects the signal level is not low, so the amplifier gain is very low, can not improve the brightness of the main screen, when the introduction of backlight compensation, the camera only the entire field of view of a sub-region, Area of the uniform signal level to determine the AGC circuit operating point.

Q:Monitor the image of the camera appeared black and white colorless situation, is this how is it?

It is PAL is now a good point of hard disk video recorders like SNA-8116-S Shenzhen Shi are supporting a variety of standard format is that some of your camera is infrared? Infrared is not open if the night infrared light to open the image is black and white

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:What kind of surveillance camera points

Infrared integrated camera, integrated camera, infrared hemisphere, ordinary hemisphere, explosion-proof hemisphere, constant speed ball, medium speed ball, high speed ball, network camera, gun camera (low light, wide dynamic, color to black) And so on.

Q:Digital camera and analog camera difference

The analog camera can convert the analog video signal generated by the video capture device into a digital signal and store it in a computer. The video signal captured by the analog camera must be converted to digital mode via a specific video capture card and compressed before it can be converted to a computer. Digital camera can capture images directly, and then through the string, parallel port or USB interface to the computer.

Q:I now on the 4th floor balcony by a monitor, the main monitoring downstairs car, what kind of camera is good

Probably give you the next, the higher the number of lines the better the clarity of the camera, 480 lines enough for you to use, as the number of the larger number of millimeters, the narrower the narrow range, but clearly, the small number of meters wide to see the corresponding objects smaller

Q:Monitor the camera's focal length how to choose?

Third, because the lens focal length and horizontal perspective is inversely proportional, so both want to see far, want to see wide and clear, it can not be achieved at the same time. Each focal length of the lens can only be in a certain range to achieve the best monitoring effect, so if the monitoring of the distance and a larger range, it is best to increase the number of cameras, or the use of electric zoom lens with PTZ installation , Of course, this for the civilian use, some expensive, and practical will not increase greatly.

Q:How to install a surveillance camera

2. For the first time, the system may search the driver to install, free of charge can be identified, can not help but may also download the file automatically install the driver, the next time you insert the time will be much better.

Q:Can the general camera be monitored?

Ordinary camera: ordinary personal computer + ordinary USB camera + software, the establishment of cheap USB camera monitoring system. Applicable to individuals who do not have any requirements.
