Why this decision matters
Backup for one component does not prove the complete required function remains available.
Work through the actual task
- List every powered component between camera and stored footage.
- Ask for a backup design based on the complete load, including the switch.
- Ask the installer to explain the documented backup design and safe test procedure for your equipment.
Worked example
The recorder has backup power but cameras use a separate switch. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: The equipment/load list and the manufacturer's stated backup assumptions.
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.
