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
- List required functions, users and intended phones/displays.
- Confirm which are local, cloud-based or model-dependent.
- List your three priorities and ask the installer to show how the proposed design meets each one.
Worked example
An owner needs alerts while staff need viewing only. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: An account-role/function brief before choosing the platform.
Limits and follow-up
Avoid exposing recorder ports directly to the internet. Discuss supported secure access options and keep the device software maintained.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
