An important point when choosing cameras for video surveillance is their quality, or as they say, resolution. This parameter determines how detailed the image will be. Simply put, the higher the resolution of the cameras, the video will be clearer and better.

Resolution is measured in megapixels. The more megapixels, the higher the image quality. The price depends on the quality of video cameras. High resolution cameras cost significantly more. In general, it is worth choosing cameras with a resolution of at least 2MP (this is the FullHD format - 1080p).
