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,: Mode. CMOS is complementary to each other metal oxide semiconductor, CMOS is mainly the use of silicon and germanium made of these two elements of the semiconductor, through the CMOS on the negatively charged and positively charged transistor to achieve the basic functions

Q: Wireless remote monitoring camera farthest to monitor how far: As long as there is a mobile Internet, where you can see, there is no distance limit. The

Q: What is the difference and connection between the optical zoom and the digital zoom of the camera in the security monitoring?: Optical zoom is that we often say that the mechanical zoom (manual and automatic), manual is the lens we usually zoom, auto zoom is common is that we use the ball machine and PTZ to pull closer to control zoom.

Q: How many mm meters I use to monitor the camera: 4, non-infrared camera power is very small, four cameras share a 2A power supply is sufficient, if there is no 2A, 1A line, but the power margin is small.

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?: Modify the last two digits of each camera is like a 192.168.1.11,192.168.1.12, ...

Q: The working principle of the camera with infrared light: Infrared emission diode (IR LED) infrared lamp principle is: by the infrared light-emitting diode matrix composed of light. Infrared emission diode from the infrared radiation efficiency of high materials (commonly used gallium arsenide GaAs) made PN junction, plus forward bias voltage to the PN junction injection current excitation infrared light. Spectral power distribution for the central wavelength of 830 ~ 950nm, half-peak bandwidth of about 40nm or so, it is narrowband distribution, for ordinary CCD black and white camera can feel the range. The emission power of the infrared light emitting diode is expressed by the irradiance μW / m2. The maximum radiation intensity of the infrared diode is generally in front of the optical axis and decreases with the increase of the angle between the radiation direction and the optical axis. The radiation intensity is 50% of the maximum value of the angle is called the half intensity radiation angle, that is, half power angle. The radiation angle of the infrared light emitting diodes of different packaging process models is different.

Q: What is the number of lines that a surveillance camera needs to use?: 2, video cable (transmission video signal, syv75-3, syv75-5, syv-75-7 these three are the most commonly used)

Q: Infrared surveillance camera at night (no light) no picture and flash is how the matter: Check the time, pick the evening when people come close to the camera from the place to see if the infrared light is not activated, if the start, the infrared light will have a very weak red visible light is always bright. If there is no red visible light or not always bright, it can be basically the problem of infrared light. Of course, you also need to check whether the power is normal, if the voltage is low or the current is too small, it may cause the infrared light does not work.

Q: Monitor the camera screen black: Acquisition card problem if not your driver is not installed. That is the acquisition card itself is a problem

Q: Monitor the camera feel infrared: In the case of the camera with infrared light, the evening can rely on infrared imaging color lens, no light at night is not visible in the case of objects
