Class Audit Methodology
Winnowl Standard Specs (Calculated)
Storage Capacity (GB) / (((Recording Bitrate (Mbps) * 86400) / 8000) * Number of Cameras (cameras))
Storage capacity in gigabytes does not indicate how many days of footage a system saves before overwriting old video. Winnowl models Continuous Retention Days by analyzing hard drive capacity against camera resolution and estimated recording bitrates for all included cameras operating 24/7. This provides a comparison of recording duration without relying on drive size alone.
(sqrt(Camera Resolution (MP) * 1000000 * (16 / 9)) / 152)
Camera resolution specifications do not account for optical lens quality or sensor limitations during daylight operation. Winnowl calculates Day Identification Distance to estimate the operational range at which a target subject can be identified under daylight conditions. This offers an objective benchmark for useful video detail when evaluating potential evidence.
Day Identification Distance (ft)/2
Standard manufacturer night vision ratings measure the distance at which a camera can spot a moving shadow, not whether facial features are legible. Winnowl estimates Night Identification Distance to evaluate the distance where facial detail and license plates are expected to remain readable in low-light conditions. This replaces unverified manufacturer range claims with a practical baseline for usable night security.
(Camera Resolution (MP) >= 9.6 ? 8.5 : (Camera Resolution (MP) >= 7.6 ? 6.0 : (Camera Resolution (MP) >= 5.6 ? 5.0 : (Camera Resolution (MP) >= 3.6 ? 4.0 : (Camera Resolution (MP) >= 2.6 ? 3.0 : (Camera Resolution (MP) >= 1.8 ? 2.0 : 0.0))))))
High camera resolution requires a proportional recording bitrate to prevent frame corruption and pixelation during fast movement. Since most manufacturers do not publish bitrate, Winnowl uses industry standards for comparison.
Manufacturer Stated Specs
Manufacturer night vision specifications reflect maximum infrared illuminator projection, which does not measure picture detail or target clarity. We assign zero weight to this metric because it overlaps with—and is superseded by—Winnowl’s Night Identification Distance. While claimed range indicates light throw, our calculated metric evaluates estimated readable detail.
Raw hard drive capacity in gigabytes is misleading without factoring in camera count and data throughput. We assign zero weight to raw storage capacity because it overlaps directly with Winnowl’s Continuous Retention Days. Raw gigabytes serve as an input calculation variable in our backend database, while retention days provide the actionable metric for recording duration.
