Security System Reuse and Migration Checklist

What can stay when you upgrade security?

Start with the equipment and the task it must perform. Tec-Tel can help assess existing cameras, recording, access control and cabling before scoping a replacement. This checklist separates confirmed reuse from items that need testing, and keeps recording continuity and administrator handover in the plan.

Build one inventory before comparing proposals

Use the blank equipment inventory worksheet to give competing proposals the same starting point. Record unknowns honestly. A missing model number is a survey task, not proof that equipment must be replaced.

Cameras: model, firmware, required view, recording settings and current VMS connection.
Doors: readers, controllers, credentials, locking hardware and who owns the entrance.
Infrastructure: cabling, power, network responsibility and recording/storage equipment.

Assign each item a decision

Retain when supported compatibility and condition are established. Test when a dependency remains uncertain. Replace when the required function or applicable specification cannot be met. Retire when the view or access point is no longer required and its owner approves removal.

Ask the proposer to identify the source for each reuse decision. A supported-device list is useful, but your acceptance test must also cover the actual function. For example, live video alone does not establish usable event search, export or PTZ control.

Test the work people actually do

One representative incident: locate a clip, export it and play it back using an authorized operator account.
One representative access change: enroll and revoke an approved test credential, then confirm the intended doors respond correctly.
One controlled recovery: agree on a safe interruption test and verify the recording or access behavior specified in the design.

Document success criteria, exceptions and the person who accepts the result. Tests involving occupied doors or live recording must be planned with the responsible site staff; do not interrupt a production system just to complete a checklist.

Make the transition part of the quote

Include temporary overlap, retention of historical recordings, account ownership, rollback decisions and support after handover. Specify who updates camera names, door schedules, administrator permissions and the equipment register.

Separate one-time equipment and labor from recurring licensing, cloud retention, support and renewals. Use the five-year quote worksheet with the same assumptions for every option. Neither a cloud subscription nor retained hardware guarantees the lower total cost.

Start with a short project description

Share the location, number of sites, approximate camera or door count, existing platform and intended timing. Tec-Tel can discuss the assessment and installation scope before a detailed design is commissioned. Book a free consultation or call 855-577-0400.

For device-specific checks, consult the current Milestone supported-device resources and Verkada Command Connector documentation. Requirements differ by platform and model. See camera installation, access control and cabling for the physical scope.

Frequent buyer questions

Does ONVIF support guarantee every feature will transfer?

No. Check the exact camera model, firmware, driver and target platform. Test the functions you need, including events, PTZ, audio and analytics where applicable. A working video stream is only one part of acceptance.

Can we keep existing door readers and credentials?

Potentially. Identify readers, controller hardware, credential technology, wiring, locks and the proposed platform. Ask for supported combinations and test enrollment, access changes and revocation. Door egress and other applicable requirements need appropriate review.

Can we move old recordings into a new VMS?

Do not assume an import path exists. Plan archive access or export, verify playback, and document retention and access permissions before the old recorder or subscription is retired.

Should we upload equipment lists or passwords here?

Keep this worksheet internally until the team agrees on a suitable sharing method. Do not put passwords, sensitive floor plans, footage or public IP addresses in a website enquiry. A location, approximate equipment count and project goal are enough to begin.
