How to choose monitoring poles and how to standardize installation

Selection and installation of surveillance cameras:

1. Choose according to the installation method. For fixed installations, surveillance cameras mostly use ordinary surveillance cameras or dome surveillance cameras. If they adopt the PTZ installation method, integrated surveillance cameras are now mostly used, such as SANNO's SN-220C. Its characteristics are: built-in electric zoom lens, compact and beautiful, easy to install Convenient and cost-effective, you can also use an ordinary surveillance camera with an electric zoom lens, but the price is relatively high and the installation is not as easy as an integrated surveillance camera.

2. Select according to the installation location. Since ordinary surveillance cameras can be installed on both walls and ceilings, they are not restricted indoors or outdoors and are more flexible. However, hemispheric surveillance cameras can only be installed on the ceiling, so they are mostly used indoors and have certain installation height restrictions. But compared with traditional cameras, there is no need for additional lenses, protective covers, and brackets. It is easy to install, beautiful and concealed, and is economical.

3. Choose according to the ambient light. If the light conditions are not ideal, you should try to use surveillance cameras with lower illumination, such as color ultra-low illumination surveillance cameras, color and black-and-white automatic conversion dual-purpose surveillance cameras, low-illumination black-and-white surveillance cameras, etc., to achieve better collection results. It should be noted that if the light illumination is not high and the user has high requirements for the clarity of the surveillance image, a black and white camera should be used. If there is no light, you must add infrared lights to provide lighting or choose a surveillance camera with infrared night vision function, such as SANNO's SN-350CWH or SN-350CW surveillance camera. Its characteristics are: the surveillance camera itself has a color black and white conversion mode, automatically With lens and mounting bracket, unique vacuum packaging design, no need to install a protective cover when used indoors, beautiful appearance, good concealment, and excellent cost performance.

4. Choose according to the requirements for image clarity. If the resolution requirements for image quality are higher, a surveillance camera with a higher TV line index should be selected. Generally speaking, for color surveillance cameras, 420 and 450TVL (television line) are medium-resolution surveillance cameras, and 470TVL and above are high-resolution surveillance cameras. The higher the definition, the higher the price.

5. You should also pay attention to some performance indicators on the product description. Such as signal-to-noise ratio, automatic iris lens driving method, etc. In a general TV surveillance system, the signal-to-noise ratio index should be greater than 48dB. This not only meets the requirement of not less than 38dB stipulated by industry standards, but more importantly, when the ambient illumination is insufficient, the higher the signal-to-noise ratio, the worse the image of the surveillance camera. Clear. The driving mode of the lens generally adopts dual driver, so that you can choose DC driver or video driver automatic aperture lens.

6. In addition, security surveillance cameras should be installed more cautiously. Strictly follow the product instructions for correct operation, such as operating temperature, power supply voltage, etc. The temperature indicators of most surveillance camera manufacturers are -10~+50℃. If the temperature and humidity in the area of ??use change greatly, special protection should be added. Since the AC voltage adaptability range of domestic surveillance cameras is generally 200-240V, and their ability to withstand changes in power supply voltage is weak, a regulated power supply is required when used in the system.
