Why this decision matters
A photograph of one device cannot establish all relevant cable, power, lighting and operating conditions.
Work through the actual task
- Discuss trading, deliveries, public access and after-hours occupancy.
- Walk the relevant routes and mark target views/restricted spaces.
- Ask for the proposed positions and any unresolved assumptions to be marked on a simple plan.
Worked example
The survey happens after closing but deliveries use another entrance. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A survey plan covering the full operating cycle.
Limits and follow-up
Agree a service scope in writing. Hardware supply, cabling, networking, monitoring and response attendance may be priced separately.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
