- Q: Night to monitor the infrared light is not bright because it is not open monitoring?
- 1: equipment power supply problems, open the infrared light to monitor the camera power is not open than the big, generally do not open when the 2 to 3 times the power, if the power quality, but the line is not enough, the total power supply UPS power is not enough Open the infrared light
- Q: Seeking a few surveillance camera manufacturers
- Hai Kang, Dahua, Yu as, with the Corning are domestic good, to see where you want to use, the environment is different from the choice of the camera is also different, the price gap is also great,
- Q: Monitor what is good for video recorders
- Dahua's software is easy to use, but DVR's BNC plug is easy to loose, resulting in poor contact, sometimes the channel screen will not show or interfere with the screen.
- 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,
- of. The current generated by these two complementary effects can be recorded and interpreted by the processing chip as an image. CMOS CCD for the most important advantage is very power. Unlike the diode composed of CCD, CMOS circuit
- Q: Will the video surveillance camera screen will jump out of this camera settings like the option?
- Is the camera menu is transferred out, the general ball machine class camera will appear such problems, you can power the way to cancel the camera!
- Q: What is the difference and connection between the optical zoom and the digital zoom of the camera in the security monitoring?
- Digital zoom, the software is a way to achieve the realization of electronic amplification, and more for high-definition network camera, through the camera's capture screen, the screen to enlarge the local.
- Q: How to find the camera dead ends
- Professional is this: from the camera's lowest vertical angle and 45 degrees direction of the corner shot to the ground for the vertex to draw a square to the corner, for most of the camera is within the square of the collection area is invalid, basically applicable to The market of 90 percent of the camera, very few high-value professional equipment, except, even if the square of the two sides can sweep the image of the place has been seriously deformed, there is no legal effect, this has been in court there are numerous cases
- 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: I press the Zhongwei monitoring, power and camera are good, that is not seen friends
- If the video file is modified to 0, still can not connect the image, it may be the problem of Internet cats, it is recommended to replace ZTE 831B. There may be restrictions on the Internet cat itself.
- Q: I would like to ask how the video surveillance camera is powered?
- You are right, video surveillance cameras used to make a signal with a coaxial line, and then another line when the power supply, but the two lines can also be a line to achieve. That is to use control Because the control line is a double core, with a shield, we can put the video ground, and the power of the negative line, together, sharing a line, that is, the control line of the shield, and then Inside the two core, one when the video signal is positive, one when the power is positive. This can, but if the distance is very long, it is recommended not to do so, because of this, the signal shielding will be a little interference.
