Q:Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?
If the voltage is 12V has been determined. The current is determined. The current is determined by the DC impedance of the camera. If the voltage changes, the current will change. If the camera is shorted. That its voltage also changed!
Q:What is the 960h in the surveillance camera?
960H is a set of quasi-HD solutions defined and developed by Techwell and Sony, which incorporates Sony's new generation of 960H CCD Sensor and Effio solutions, and the DVR side uses Techwell's latest TW9960 analog quasi-HD A / D solution. 960H resolution of 960 * 576, relative to the traditional D1 (720 * 576) overall picture clarity (details) increased by 30%. For the original analog monitoring system to upgrade the upgrade, only the front-end camera and back-end storage replaced by 960H products, transmission part can continue to follow the original system coaxial cable, the system architecture and the original analog system basically unchanged, Engineering and users without the need for professional skills training can be the original D1 system upgrade to 960H quasi-HD, the overall increase in the screen 30% at the same time will not change the user's habits, suitable for limited budget but want to experience " User.
Q:I would like to ask how the video surveillance camera is powered?
  Wiring, or to use two lines of good, if their own home, then, with a control line does not matter, but to the customer with the words, or two good, so look more professional, the probability of the problem comparison Smaller.
Q:What is the difference between a camera's double point and a single lamp point?
The camera's double dot-in-the-spot light and single-digit array lamp is just a different number of infrared light popular name, there is an array of infrared light camera called single lamp array, two is called double lamp array.
Q:Monitor the camera 1 road 4 what is the difference
Very simple This is for the camera's hard disk video recorder to the general are at least 4 Road 8 Road 16 Road 32 Road, a camera all the way, there are 16 points can be connected to 16 points is 16 cameras.
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:What kind of monitoring camera is used in the store? 360 ° with the introduction of ordinary
If the store to install two, generally use diagonal installation, select 3.6MM lens, the basic can see the whole store (of course, the store is not big, about 20 square).
Q:The working principle of the camera with infrared light
Second, the infrared camera imaging principle In the night vision monitoring system, the conventional approach is to use the visible light, but this way there can not be hidden, easy to monitor the target and other shortcomings, so use less; the current hidden, scientific night vision monitoring Is the use of infrared camera technology. Infrared camera technology is divided into passive and active. Passive infrared camera technology is the use of any substance in the absolute zero (-273 ℃) are more than infrared radiation, the higher the temperature of the object, the more infrared radiation. The most typical of the cameras made with this principle is the infrared camera, but this special infrared camera is expensive and therefore limited to military or special occasions. The active infrared camera technology is the use of infrared light radiation "lighting" (mainly infrared light), the application of ordinary low-light black and white camera, color to black and white camera or infrared low-light color camera, feel around the scene and the environment reflected back to the infrared light to achieve Night vision monitoring. Active infrared camera technology is mature, stable, become the mainstream of night vision monitoring.
Q:A camera for an hour how much space
This depends on the camera to shoot the quality of the picture, give you a camera 130W, each picture is 30K look, the picture is 10 Zhen, then every 10 is the screen, that is 300K, 1 hour 3600 seconds , Take out 1080000KB to remove 1024, that is, 1G look like
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.
