Q: How to use video surveillance video surveillance: Whether it is Hai Kang, Dahua, Degas or Kang silver video capture card, their function is video capture, and then? Compression, otherwise, so much of the data stream burned the CPU, they are only responsible for the collection, that is, you can now achieve the function - video. To achieve the function you say is also very simple, according to your idea, have to buy a video decoder card, because the acquisition card data collected after compression can not communicate with the qq software (protocol is different), through the decoder card , The compressed data is reduced to analog (or digital) signal, through the USB interface can achieve what you said the function.

Q: Camera clarity, 1080p. 3mp. 4k, what does it mean: 3MP, 3 million pixels should be valid pixels or still photo pixels

Q: 20 meters away with the number of mm monitor camera lens appropriate?: At the same time, the same focal length, length and width shooting range also with the camera CCD has a relationship. Charge - coupled Device, Charge - coupled Device. It is a semiconductor device that converts optical images into electrical signals. At present, most of the CCD chip used in the surveillance camera is 1/3 "and 1/4", that is, the target size is 1/3 inch and 1/4 inch. CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity.

Q: Is the camera pixel taller the better?: But because of the current network bandwidth limitations, really very high physical pixels in the video screen may be cards, depending on your network. Now most of the camera on the market is 30W physical pixels, said hundreds of millions are blowing, a few can reach 130W physical pixels, but expensive, Logitech is currently the highest pixel is only 200W, so 800W, 500W those are Is interpolated, there is no practical significance.

Q: What is the name of the camera with the monitor?: Infrared waterproof integrated camera I have two, you see is not what you want!

Q: Hai Kangwei as the camera mapping problem: The default is 192.168.1.1 I changed to 192.168.1.66, in fact, are the same friends.

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: Test on camera delay problems: Test the network infrared camera delay problem is very simple, only need to monitor the camera at high precision stopwatch, so that the reality of the image and display the image contrast, through multiple arrests we can calculate the IPC delay time.

Q: Can the general camera be monitored?: All cameras can be monitored, but not all cameras are suitable for monitoring. The purpose of monitoring is to clearly record the process of the incident, which requires the performance of the camera as a monitor to suit the work environment, site conditions and other requirements.
