Why this decision matters
A feature list cannot show whether the intended person can reach, read, hear or complete the actual control task.
Work through the actual task
- Try text size, controls and event review on the actual device.
- Discuss supported accessible workflows or a more usable viewing display.
- Have the intended users try the proposed control method before committing to a final position.
Worked example
A user has difficulty navigating recorded footage on a small phone. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A demonstrated everyday method the user can repeat independently.
Limits and follow-up
Avoid exposing recorder ports directly to the internet. Discuss supported secure access options and keep the device software maintained.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
