Inventory the installed system
List cameras, lenses, coax routes, recorder inputs, storage, power, users and useful views. Separate positions that still answer an incident question from those that need a new angle.
Decide how to phase the cutover
A temporary encoder or hybrid recorder may preserve selected legacy feeds, subject to compatibility and support. Plan the network, PoE budget and outage window before replacing equipment in an occupied facility.
Prove the new evidence workflow
Check nighttime images, retention assumptions, health alerts and authorized export. Train users on the new client software and keep the record of what was retired and what remains.
Working example: The scenario below is illustrative. It describes a practical design and review method, not a completed customer project or a guaranteed result.
A working scenario
An analog recorder is replaced, but legacy cameras, coax paths, export procedures, and old footage retention were not scoped. The new server alone cannot create a seamless migration.
The decision to make before buying
Inventory channels, actual image quality, analog-to-IP encoders if proposed, power, storage, network capacity, licenses, and evidence preservation. Decide which views can be phased and which require overlap during cutover.
A useful acceptance test
Before disconnecting the old system, capture a sample event from both environments, verify timestamps and export, then test retention and camera failure alerts on the new recorder.
What the owner should receive
Keep a mapping of old channel to new camera, cutover sequence, access rights, preserved evidence instructions, and decommission decisions. Tell operators exactly where to find pre-migration footage.
Questions owners ask
What data can be lost at cutover?
Archived footage, user permissions, camera names, event bookmarks or the ability to play an old export can be overlooked. Inventory each before retirement and agree on retention and lawful access with the owner.
What should the cutover rehearsal show?
A sample event recorded and retrieved on both paths, current clock alignment, operator access and recovery if the new recorder fails. Retain the old system only for the approved overlap period and document its decommission.
Project conditions and responsibilities vary. Confirm the actual scope and test plan with the owner and project team.
