The old system still works. A security system upgrade keeps what is good.
Analog cameras you want on IP, card readers from the Wiegand era, a telephone entry panel on a copper line that is being retired, or a server you want in the cloud. We plan upgrades that keep what works and replace what matters.
Keep the camera positions and often the existing coax, using HD-over-coax or converters, or re-pull where the cable is the limit.
Analog cameras to IP
Keep the camera positions and often the existing coax, using HD-over-coax or converters, or re-pull where the cable is the limit.
On-site access control to cloud
Aging on-site servers move to a cloud platform. Users and cards migrate, and readers and locks stay where they can.
Old readers to OSDP
Older Wiegand readers upgraded to OSDP, the secure modern reader standard. Often possible on the existing wiring.
Copper phone line to cellular
Carriers are retiring copper phone lines. We convert telephone entry panels to cellular, or replace them with cellular panels, keeping the directory and how tenants use it.
Buzzer to video or app entry
Audio-only buzzer systems upgraded to video intercoms with phone answering, reusing building wiring where possible.
HDMI matrix to AV-over-IP
Matrix switchers replaced with AV-over-IP distribution, keeping compatible displays and speakers.
Keep what works, replace what matters.
An upgrade should respect what you already paid for. This is how we scope every project.
Assess what can stay
Before quoting, we check which cameras, locks, cables and infrastructure can be reused with the new system.
Phase it where it makes sense
Critical doors or cameras first, the rest later. The business keeps running and the cost is spread out.
Keep the cable, replace the endpoints
Cable is often the biggest cost. We keep existing runs wherever they meet the new system, and re-pull only where the cable is the limit.
Keep the old system running
The legacy system runs until the new one is tested and the cutover is clean. Critical doors work throughout.
Document the new system
After cutover, a record of what is new, what was kept, how it fits together and who has admin access.
Got a letter about your phone line?
Telephone entry panels, elevator phones and older alarm dialers run on copper phone lines that carriers are retiring. We convert or replace them before the line goes dead.
We start from what you already have.
Most upgrades start from systems we did not install. We audit what is there before we suggest anything.
Every system we upgrade
Each hub below covers that system in detail.
Common upgrade paths
The most common paths we take, each keeping as much of the existing system as the new one allows.
Honest trade-offs.
When the upgrade pays
When the old system costs more to keep running than the upgrade costs, or it cannot do what you now need.
When to wait
When the existing system has more useful life than the upgrade would gain. We tell you that too.

Four stages, from scope to sign-off.
Discovery and scope
We walk the site, audit the existing system, find what can stay, and talk through your goals, budget and timeline.
Design and quote
New components, cable work, a phased plan and how users and cards migrate. A clear quote before any work.
Phased install
New gear installed alongside the old, tested, then cut over one system at a time where possible.
Cutover and handover
Final cutover, every part tested, documentation delivered, and your team shown how to use the new system.
