Why this decision matters
Comparing hardware prices alone can hide different labour, compatibility and recurring-service assumptions.
Work through the actual task
- Compare readers, controllers, supplies, locks and release devices door by door.
- Include credential quantities, programming and software charges.
- Ask for missing items in writing and keep the accepted scope with your receipt.
Questions and evidence to request
| Question | Useful evidence in the scope |
|---|---|
| Which doors and time periods should each role be allowed to use? | A door, role and time schedule matching the actual operating needs. |
| Who can authorise a credential or revoke one that is lost? | A named approver and a demonstrated credential revocation procedure. |
| Are the existing locks, frames and closers suitable? | A complete door-hardware assessment rather than a reader-only equipment list. |
| What functions continue if internet or power is interrupted? | A door/function dependency record covering the agreed outage behaviour. |
| Which records are needed and who is authorised to view them? | A record-access policy and a responsible administrator for the required information. |
Worked example
A low reader price excludes lock and exit hardware. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A complete installed-door scope rather than a reader-only price.
Limits and follow-up
Door security must preserve safe exit. Have the appropriate qualified professionals confirm the door and emergency release design.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
