First, according to ambient light <br> <br> selected if the light conditions are not ideal, we should try to use low illuminance surveillance cameras, such as color illuminance over the end surveillance cameras, black and white color dual-use automatic conversion surveillance cameras, black and white monitor illumination Cameras, etc. to achieve better collection results. It should be noted that if the illumination of the light is not high and the user has high requirements for monitoring the image sharpness, the black and white surveillance camera should be selected. If there is no light, you must add infrared lights to provide lighting or use surveillance cameras with infrared night vision.
Second, the monitoring of the installation site <br> <br> due to the general gun-type surveillance cameras, but also both wall-mounted ceiling installation, indoor and outdoor unrestricted therefore, more flexible; and the hemisphere surveillance cameras, ceiling installation only, so multi-purpose Indoor and installation height is limited. However, compared with the gun-type surveillance camera, there is no need to reprovision the lens, protective cover, and bracket, which is convenient to install, beautiful and concealed, and the price is economical.
Third, the installation <br> <br> as fixed installation, surveillance cameras use an ordinary gun multiple surveillance cameras or surveillance cameras hemisphere; The installation uses head, now integrated multi-use surveillance cameras.
Fourth, according to the requirements of image resolution selected <br> <br> If resolution of the image quality higher, the higher should be used in cable television cameras monitoring indicators. The higher the sharpness, the higher the price.
V. Installation <br> <br> caution strictly follow the instructions for correct operation, such as operating temperature, supply voltage and so on. The majority of surveillance camera manufacturer's temperature index is -10 ~ +50 °C, such as the use of the area temperature and humidity changes should be added special protection. As the domestic surveillance camera AC voltage adaptation range is generally 200 ~ 240V, anti-power voltage change ability is weak, when used in the system need to add regulated power supply.
Sixth, we should also pay attention to some performance indicators such as drive type <br> <br> signal to noise ratio, auto-iris lens on the product description. The signal-to-noise ratio of the general TV monitoring system must be greater than 48dB, which not only meets the requirements of the industry standard of not less than 38dB. More importantly, when the ambient illumination is insufficient, the higher the S/N ratio, the more the surveillance camera image becomes. Clear. The drive mode of the lens is generally dual-drive, so that you can use the DC or video-driven auto iris lens.
