Live-site upgrades without
downtime.

Most security upgrades have to happen on a live site.

Commercial sites rarely shut down for a security refit. The building keeps trading, staff keep working, tenants keep coming and going - and the existing system has to keep doing its job until the new one is taking over. Done badly, that gap is when the site is most exposed.

This piece sets out the practical principles we use on live-site upgrades so the building is never left without a working security system during the change.

What to plan for before work starts.

• check_circleMap every current device and its function - cameras, panels, readers, signalling paths
• check_circleIdentify the dependencies between subsystems - what an alarm panel signals, what cameras a recorder covers
• check_circleAgree the stages and the cut-over criteria for each one in advance with the operator
• check_circleConfirm out-of-hours access arrangements for the install team - and the security cover during them
• check_circlePlan a fallback for each stage - what happens if a cut-over fails on the night
• check_circleBrief the people on the ground - reception, security, facility staff - on what to expect
• check_circlePlan the final commissioning and handover so the operator owns the new system properly

Get the staging right from the start.

The single most useful thing on a live-site upgrade is a stage-by-stage plan agreed before the first piece of equipment is touched. We work through that plan with the operator at the start of every refit and treat it as the working document for the duration of the job.

If you have an upgrade coming up - or you are running an ageing system and not sure how to replace it without leaving a gap - we can help you scope it.
