Below is a detailed explanation of each input.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Number of Cameras<\/h3>\n\n\n\n<p>This is the number of cameras within a specific group that share identical recording settings.<\/p>\n\n\n\n<p>If your installation includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>6 \u00d7 4MP indoor cameras<\/li>\n\n\n\n<li>2 \u00d7 8MP outdoor cameras<\/li>\n<\/ul>\n\n\n\n<p>You should create <strong>two camera groups<\/strong>, not one.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Resolution (Megapixels)<\/h3>\n\n\n\n<p>Resolution directly affects bitrate and storage consumption.<\/p>\n\n\n\n<p>Higher megapixel cameras produce more detailed images but require more storage space.<\/p>\n\n\n\n<p>Typical impact:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>2MP: Low storage requirement<\/li>\n\n\n\n<li>4\u20135MP: Moderate storage requirement<\/li>\n\n\n\n<li>8MP (4K): High storage requirement<\/li>\n\n\n\n<li>12MP: Very high storage requirement<\/li>\n<\/ul>\n\n\n\n<p>Doubling resolution does <strong>not<\/strong> exactly double storage, but it significantly increases it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Frame Rate (FPS)<\/h3>\n\n\n\n<p>Frames Per Second (FPS) determines how many images are recorded each second.<\/p>\n\n\n\n<p>Higher FPS increases storage linearly.<\/p>\n\n\n\n<p>In most CCTV installations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>12\u201315 FPS is sufficient<\/li>\n\n\n\n<li>20+ FPS is rarely necessary<\/li>\n\n\n\n<li>25\u201330 FPS dramatically increases storage<\/li>\n<\/ul>\n\n\n\n<p>For general surveillance, reducing FPS is the fastest way to extend retention.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Compression Type<\/h3>\n\n\n\n<p>Compression has a major impact on storage.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>H.264<\/strong> \u2013 Older standard, larger files<\/li>\n\n\n\n<li><strong>H.265<\/strong> \u2013 Modern standard, significantly more efficient<\/li>\n\n\n\n<li><strong>H.265+<\/strong> \u2013 Enhanced optimisation (scene dependent)<\/li>\n<\/ul>\n\n\n\n<p>Switching from H.264 to H.265 can reduce storage requirements by 30\u201340%.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Scene Activity Level<\/h3>\n\n\n\n<p>This factor estimates how much motion exists in the recorded scene.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Low Activity<\/strong> \u2013 Warehouses, storage rooms, rarely used areas<\/li>\n\n\n\n<li><strong>Typical<\/strong> \u2013 Offices, shops, entrances<\/li>\n\n\n\n<li><strong>High Activity<\/strong> \u2013 Car parks, streets, busy retail<\/li>\n<\/ul>\n\n\n\n<p>High-motion scenes generate larger bitrates due to frequent frame changes.<\/p>\n\n\n\n<p>Outdoor cameras usually require higher storage due to lighting shifts, shadows, rain, and vehicle movement.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Retention (Days)<\/h3>\n\n\n\n<p>Retention is the number of days you want recordings stored before being overwritten.<\/p>\n\n\n\n<p>Increasing retention multiplies storage requirements directly.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>7 days requires half the storage of 14 days<\/li>\n\n\n\n<li>30 days requires more than double 14 days<\/li>\n<\/ul>\n\n\n\n<p>Always confirm compliance requirements before finalising retention.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How Storage Is Calculated<\/h2>\n\n\n\n<p>The calculator estimates bitrate using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Resolution baseline<\/li>\n\n\n\n<li>Frame rate scaling<\/li>\n\n\n\n<li>Compression efficiency<\/li>\n\n\n\n<li>Scene activity adjustment<\/li>\n<\/ul>\n\n\n\n<p>It then converts:<\/p>\n\n\n\n<p><strong>Megabits per second \u2192 Gigabytes per day \u2192 Total Terabytes over retention period<\/strong><\/p>\n\n\n\n<p>A 25% safety margin is automatically added when recommending a hard drive size to account for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Scene variation<\/li>\n\n\n\n<li>Night-time IR noise<\/li>\n\n\n\n<li>Encoding differences<\/li>\n\n\n\n<li>Future expansion<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Important Notes<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Actual storage may vary depending on camera manufacturer, firmware, GOP settings, and scene complexity.<\/li>\n\n\n\n<li>AI analytics, object detection, and smart encoding can increase or reduce bitrates depending on configuration.<\/li>\n\n\n\n<li>Always verify storage performance during commissioning.<\/li>\n<\/ul>\n\n\n\n<p>This calculator is intended as a professional planning tool to assist installers and system designers in selecting appropriate storage
