Where is it better to install monitoring at home, and what is better?

For fixed installation, the common * type surveillance camera or hemispherical surveillance camera is usually selected. For pan/tilt installation, an integrated monitoring camera, such as SN-220C of SANNO, is usually selected. Features: built-in electric zoom lens, compact and beautiful, easy to install, high cost performance. The common *-type surveillance camera with electric zoom lens can also be used, but the price is relatively high and the installation is not as simple as the integrated surveillance camera.

Select according to ambient light:

If the lighting conditions are not ideal, we should try our best to choose low-illumination surveillance cameras, such as color over-the-bottom illumination surveillance cameras, color black-and-white automatic conversion dual-purpose surveillance cameras, low-illumination black-and-white surveillance cameras, etc. In order to achieve better acquisition effect. It should be noted that if the illumination is not high, and users have high requirements for the clarity of the monitored image, they should choose a black-and-white camera.

If there is no light, you must add an infrared lamp to provide illumination or choose a surveillance camera with infrared night vision function, such as SN-350CWH or SN-350CW surveillance camera of SANNO. Its characteristics are: the surveillance camera itself has a color black-and-white conversion mode, with its own lens and mounting bracket, unique vacuum packaging design, no need to install a protective cover when it is used indoors, beautiful appearance, good concealment and excellent cost performance.

Monitored performance indicators:

Such as signal-to-noise ratio, driving mode of automatic aperture lens, etc. In the general TV monitoring system, the signal-to-noise ratio is greater than 48dB, which not only meets the requirement of not less than 38dB stipulated by the industry standard, but more importantly, the higher the signal-to-noise ratio, the clearer the surveillance camera image will be in the case of insufficient ambient light. The driving mode of the lens is generally dual-driving, so as to choose DC-driven or video-driven automatic aperture lens at will.

In addition, it is worth noting that it is best to buy brand-name cameras, which are more secure in terms of quality, technology, after-sales service and life. And famous brands can't do it in this respect.
