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.
Q:Dahua monitor a single image upside down, the rest of the camera are good, how the matter, had been good!
The camera back to security, Guangan Lei Ke security for you to answer
Q:Monitor camera parameters how to see the bigger the bigger the better?
Suitable for the best is the Yeah, professional monitoring, space information
Q:What is the meaning of monitoring the focal length in the camera?
So, you want to see a wide range, to choose a small aperture of the lens, but to see the target will be smaller.
Q:The working principle of the camera with infrared light
First, the characteristics of infrared and infrared light light is an electromagnetic wave, with the same nature as the radio waves. Its wavelength range is from several nanometers (1nm = 10-9m) to about 1mm (mm). The visible wavelength is from 380nm to 780nm, the wavelength of visible light from long to short into red, orange, yellow, green, blue, blue, violet, the wavelength is shorter than the purple light, the wavelength of visible light is only a part of the visible light, visible light Called ultraviolet light, the wavelength is longer than the infrared light called infrared light. Infrared light wavelength between 780nm ~ 1000μm, located between the radio and visible light. Infrared light according to its infrared radiation mechanism is divided into semiconductor solid light (infrared emission diode IR LED) infrared light and heat radiation infrared light two. At present in the CCTV infrared camera in the former use more.
Q:Hai Kangwei depending on the surveillance camera how to achieve continuous automatic capture, such as a second catch a?
Hai Kang hard disk video recorders to add network cameras: 1, first installed the network camera, connected through the network cable to the switch, the network camera connection is not the need for each network cable must be unified in a switch (such as: need in the distance Install a camera

Color it. From the quality point of view, basically what is called the brand, are very durable, not easy to bad.
Q:Network monitoring camera how to change ip
Most of the network camera has matching software, the software can search the camera and can set the camera IP, want to see the video recorder in the external network, then directly to the video recorder port mapping on the line, like the analog video recorder. In the camera factory will have a CD with the machine, the CD has a corresponding camera software which has a search software, through the search software can see the IP address assigned to the camera and re-fill the port suggested that the port fill between 1025-65535 Data, and IP address must be on the same network with the local computer, the first four different instructions have a corresponding diagram.
Q:Camera monitor the recorded file 1 hour how much G ah?
3600 seconds (per hour) * 24 hours (per day) * Rate (128kbps-8Mbps) / 8 (conversion of bytes and bits) / 1024 (converted to M) / 1024 (converted to G) ≈21G (bit rate is To 2Mbps for the column)
Q:Monitor knowledge! 1.2 m × 20 meters of the corridor with a large angle of the camera the best?
According to my experience, the first with 6mm lens, the second with 3.6 or 4mm lens is better.
