 Surveillance camera knowledge 
 A. Monitor the camera lens 
 Focal Length: surveillance camera's focal length is the distance between the lens and the sensor. Magnification of the lens is approximately equal to the focal length and object distance ratio. In other words, with the monitor the camera focal length increases, the increase in magnification close-range pull far more clear vision of the details, on the contrary, was established. 
 Category: surveillance cameras can be based on the size of the lens or iris classification according to the needs of the time of purchase, you can choose different types of surveillance cameras. 
 Two. Photosensitivity 
 Want to improve the clarity of surveillance camera images collected, it must increase the photosensitivity of the camera in the camera, the CCD sensor is 3-10 times that of CMOS, it can be a better light-sensitive access to the optical signal, and then converted to electrical signals, Finally, the video signal output or storage after treatment. 
 3. Monitoring camera control 
 In order to achieve maximum observation range of surveillance cameras, surveillance cameras must be able to rotate, the present method is to use the head to install and fixed surveillance cameras, in order to rotate. 
 In addition, you must be able to achieve the electric zoom, zoom. This requires the monitoring camera in the camera can achieve fast, accurate auto zoom. It has also become a standard to judge the surveillance camera good or bad. 
 4. Monitor the camera image transmission 
 The most widely used means of transmission is analogue cameras, digital hard disk recorders and computer network systems, collaborative work to achieve the transfer. 
 5 Glossary of surveillance cameras 
 (1) Resolution: use of surveillance cameras in the resolution refers to the points shown in the screen horizontally and vertically. The higher the resolution of the surveillance cameras capture images more clear. 
 (2) clarity: clarity of surveillance camera line said, divided into horizontal and vertical lines, lines more, the higher the resolution, imaging will be clear. 
 (3) The signal to noise ratio: refers to the monitor camera signal frequency and the power of the clutter frequency than the commonly used DB. The higher the SNR surveillance camera, the better, the better the image signal, the image is more clear. 
 (4) White Balance: White balance is to describe the white display red, green, and blue tricolor mixed generated an indicator of accuracy. By adjusting the monitor the camera's white balance in camera, you can improve the quality of the screen color. 
 (5) Backlight compensation: when camera is in shooting backlit environment, the picture will appear black image. 24 hours of surveillance cameras is not the drawbacks, then you need the backlight compensation. With the backlight compensation function, if the camera detects a region of the captured images in the video level is relatively low, will increase the amplitude of the output video signal, the image is clear.
