DESIGN FROM WHAT YOU KNOW
What are you starting with?
Representative stream sizes. Use the stream sent to the operator, which may differ from the recording resolution.
Only simultaneous views on this display, not the total site camera count.
5% is an example: one twentieth of the camera image height. Replace it with your actual target or label size.
Screen space & assumptions
16:9 panel; equal tiles; full-frame fit; square pixels; no cropping or gaps. Any unused image area is shown as letterboxing. These are geometric estimates, not a limit on an operator’s workload.
Check camera distance & isometric coverage
30% distance reduction applied.
Rectilinear lens and representative source dimensions. Use the camera’s actual horizontal angle at the selected lens setting. Camera capture requirements and operator viewing tasks are separate checks.
Lighting, field checks & calculation sources
These are planning estimates. Confirm the required task with real recorded images in the intended day and night conditions.
- Check light on the target, backlight, glare, IR reflection and illumination uniformity.
- Review motion blur, shutter speed, noise, compression and the actual recorded stream.
- Check the operator’s screen, viewing position and target visibility in the deployed layout.
Display sizing uses the reviewed public 2016 formulas. 3438 is an acuity factor. Full ANSI/AVIXA V202.01:2026 verification remains open. IEC outcomes and AVIXA viewing modes are separate choices; no equivalence or automatic compliance is claimed. The 30% camera-distance reduction is a design allowance, not a standards requirement.
