PAL typically uses 25 frames per second and a common digitized image of 720 \u00d7 576, while NTSC uses approximately 29.97 frames per second and 720 \u00d7 480. For installation, the camera\u2019s output must match the monitor or recorder\u2019s supported input.<\/p><p>The distinction becomes more complicated with AHD cameras, where suppliers may use PAL and NTSC to describe frame-rate modes at the same HD resolution. Understanding both uses helps explain why a replacement camera may fit the existing connector but still produce a black screen.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4fde2db elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"4fde2db\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b177f1e elementor-widget elementor-widget-heading\" data-id=\"b177f1e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What Do PAL and NTSC Mean in Vehicle Cameras?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-35fce4a elementor-widget elementor-widget-text-editor\" data-id=\"35fce4a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>PAL stands for Phase Alternating Line.
