Why this decision matters
A photograph of one device cannot establish all relevant cable, power, lighting and operating conditions.
Work through the actual task
- Inspect target views at relevant times and trace feasible cable routes.
- Ask how mounting angle, lens and illumination address each target.
- Ask for the proposed positions and any unresolved assumptions to be marked on a simple plan.
Worked example
A front entrance has strong afternoon backlight and a dark side passage. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A survey note identifying lighting constraints and proposed target distances.
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.
