Estimate how much recording storage your security camera system needs based on camera count, resolution, frame rate, compression, recording schedule, and retention time. This calculator helps you choose the right surveillance hard drive for NVR and DVR systems. Use the calculator below to estimate how much hard drive space your NVR or DVR needs for continuous or scheduled video recording. Security camera systems record large amounts of video data every day. The amount of storage required depends on the number of cameras, resolution, frame rate, recording schedule, compression technology, and the number of days footage needs to be retained. Higher resolution cameras such as 4K security cameras produce more detailed video, but they also require more storage space than lower-resolution cameras. Businesses storing video for 30 days or longer typically need larger surveillance hard drives than homeowners using shorter retention periods or motion-based recording. 24/7 recording captures video continuously around the clock. This ensures nothing is missed, but it requires significantly more storage because the cameras record all day long. Motion recording saves video only when movement is detected. This can dramatically reduce storage requirements and often allows footage to be retained much longer before it is overwritten. Security camera systems require surveillance hard drives designed for continuous recording workloads. These drives are optimized for multiple camera streams and long-term operation in DVR and NVR environments. A 4K security camera generally uses more storage than 1080p or 4MP cameras. Exact usage depends on frame rate, compression, scene activity, and recording hours per day. In most cases, yes. H.265 is typically more efficient than H.264 and can reduce storage requirements while maintaining strong image quality. Yes. Motion recording and scheduled recording can greatly reduce storage usage compared with continuous 24/7 recording.Security NVR & DVR Hard Drive Calculator
