Q:Monitor the difference between the camera 720p and 1200 lines
P and line, are the unit of image clarity, but P is used in the digital system, the Chinese full name for the pixel, and the line is used in the simulation system, the Chinese full name for the TV line.
Q:Ccd monitor how the camera and computer connection
1. Then buy two video connectors, a video cable, connect the capture card and camera, you can directly insert.
Q:What is the power consumption of the camera day?
This power consumption is negligible. The The 10 cameras plus 24 hours can consume about once electricity
Q:What is the difference between monitoring the camera and the usual?
Security issues: ordinary USB camera to PC-based Windows operating system, must be inserted on the computer to use. In the security, quality and other aspects of performance significantly, etc., less than monitoring the camera.
Q:What's the difference between a dome camera, a gun camera and a dome camera in security monitoring?
Ball with the above two biggest difference is that the ball can control the keyboard to control, generally installed in the need to monitor the relatively large range of the hall, outdoor large area. General bolt and hemisphere price almost. Cheaper on the hundreds of pieces, good also two or three thousand. But the ball will be very expensive, made in the thousands of good brands will reach two or three million.
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:Will monitor the camera should buy much. Room size of 8 meters 7 * 3 meters 3, is expected to use four camera monitoring head. Will the camera to buy much?
The lens can choose 3.6MM, how many lines of their own election it, the higher the more clear, now generally the highest is 700 lines.
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: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:Monitor the camera when shooting white, is the kind of white, basically do not see the image, and exposure like
It is estimated that the camera's CMOS is broken, there may be the quality of the camera is not good, the screen resolution is poor. After buying a camera or suggest you buy Hikvision fluorite camera, the effect is good, the price is not very expensive.
