8-bit (standard) 10-bit (HDR) 12-bit (professional)
Video Codec / Compression
H.265 / HEVC (best compression) H.264 / AVC (standard) MJPEG (moderate compression) Uncompressed / Raw
Quality / Compression Level
Low (50% quality) Medium (75% quality) High (90% quality) Maximum (100% quality)
Number of Cameras
Retention Period (days)
Motion / Active Recording (%)

// 1. Megapixels // MP = (width × height) / 1,000,000 var totalPixels = width * height; var megapixels = totalPixels / 1e6;
// 2. Raw uncompressed bitrate per camera (bits/s) // Raw bitrate = width × height × fps × bitDepth × 3 (RGB channels) var rawBitrate_bps = totalPixels * fps * bitDepth * 3; // bits per second
// 3. Compressed bitrate per camera (bits/s) // Compressed bitrate = Raw bitrate × codecRatio × quality var compressedBitrate_bps = rawBitrate_bps * codecRatio * quality; var compressedBitrate_Mbps = compressedBitrate_bps / 1e6;

#### Formulas Used
Megapixels: MP = (Width × Height) ÷ 1,000,000
Raw Uncompressed Bitrate (bps): Raw Bitrate = Width × Height × FPS × Bit Depth × 3 (RGB channels)
Compressed Bitrate (bps): Compressed Bitrate = Raw Bitrate × Codec Ratio × Quality Factor Codec Ratios: H.265 = 0.15, H.264 = 0.30, MJPEG = 0.50, Uncompressed = 1.00
Compression Ratio: Compression Ratio = 1 ÷ (Codec Ratio × Quality Factor)
Single Frame Size (bytes): Frame Size = (Width × Height × Bit Depth × 3 ÷ 8) × Codec Ratio × Quality
Storage per Camera per Day (bytes): Active Seconds = 24 × 3600 × (Motion% ÷ 100) Storage = (Compressed Bitrate ÷ 8) × Active Seconds
Total Storage (bytes): Total Storage = Storage per Camera per Day × Number of Cameras × Retention Days
Recommended NVR Storage: Recommended = Total Storage × 1.20 (20% overhead for filesystem, indexing, redundancy)
