Q: Monitor the camera's focal length how to choose?: Third, because the lens focal length and horizontal perspective is inversely proportional, so both want to see far, want to see wide and clear, it can not be achieved at the same time. Each focal length of the lens can only be in a certain range to achieve the best monitoring effect, so if the monitoring of the distance and a larger range, it is best to increase the number of cameras, or the use of electric zoom lens with PTZ installation , Of course, this for the civilian use, some expensive, and practical will not increase greatly.

Q: What is the 960h in the surveillance camera?: Samsung currently developed the SV5 chip with the same performance with Effio, simply said front-end use 960H CCD and Samsung SV5 chip with the use of TW9960 chip (for storage DVR) 960H

Q: What is the number of lines that a surveillance camera needs to use?: If it is a network camera is a network cable on it, the network camera to install the pickup, audio, video signals transmitted through the network.

Q: How to monitor their own home in the home camera, in the first floor, in the 5th floor to see!: Computer, the most stupid. You can only pull the video cable to your 5th floor. Power line is not used, the first floor can be directly connected. If there is a head, then you have to control the line connected to the 5th floor.

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: 6mm camera and 3mm camera What is the difference: 2, the smaller the lens to see the greater the angle, on the contrary, the larger the lens to see the smaller angle;

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: Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it: CCD, English full name: Charge-coupled Device, the Chinese full name: charge-coupled components. Can be called CCD image sensor, also known as image controller. A CCD is a semiconductor device that converts an optical image into a digital signal. The tiny photoreceptor implanted on the CCD is called the pixel (Pixel). The higher the number of pixels on a CCD, the higher the picture resolution it provides. The CCD acts like a film, but it converts an optical signal into a charge signal. CCD has a number of neatly arranged photodiode, can sense the light, and the optical signal into electrical signals, the external sampling amplifier and analog conversion circuit into digital image signal.

Q: Monitor the hard disk on the recorder is what format without formatting: Some video recorders have several hard drives. A record after the automatic record in the next hard disk. After the hard disk, you can remove the archive, put on a new one. You can not remove, then a few hard disk cycle recording, and the earliest images erased.

Q: What is the difference between a camera's double point and a single lamp point?: Array infrared night vision technology, the essence or through the camera to launch active infrared light way night vision effect, but the use of advanced packaging technology, dozens of high-power, high efficiency of the infrared crystal package in a plane. The advent of this technology, access to the extraordinary rapid development.
