Why this decision matters
Choosing the device count before defining the target task can leave important requirements outside the design.
Work through the actual task
- Mark the target distance for each view, not just the mounting point.
- Compare the proposed lens view with a person at the intended capture position.
- List your three priorities and ask the installer to show how the proposed design meets each one.
Worked example
A driveway needs an overview and a useful face image at the gate. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A camera plan stating whether each view is for observation or identifying detail.
Limits and follow-up
A recorder is not a backup. Export important clips promptly and check that the exported file plays on a separate device.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
