Connect

No system is better than the cable holding it up. This unit is the build: the network, the rack, the wireless that actually reaches the back of the warehouse, and cameras that produce usable footage. Done once, done right.

When you need it

Three signs the physical layer is holding you back.

“It slows down in the afternoon.”

And not in the morning. That is rarely the computer. It is saturation, interference, or a badly terminated cable that works until it warms up.

“Nobody knows which is which.”

A rack with forty unlabeled cables. Every change costs half an hour of pulling one and seeing what goes dark.

“The cameras are there, but…”

Footage too low-res to identify anyone, seven days of retention, or a recorder that stopped months ago and nobody noticed.

What it covers

Four fronts of work.

Network

Design and equipment

The drawing comes before the purchase order. Never the other way around.

  • Segmentation by VLAN: management, guest, cameras, production
  • Firewall with a documented rule set
  • Site-to-site and remote access VPN
  • Secondary circuit with automatic failover
  • Managed switches with PoE where it belongs

Cabling and rack

Certified build

Cat6 certified with an instrument, not tested with a laptop.

  • Runs in tray or raceway, no power crossings
  • Point-to-point certification with a report per drop
  • Patch panels, managers and correctly sized patch cords
  • Rack mounted, ventilated, front access clear
  • UPS sized and load-tested

Wireless

Surveyed first

The number of access points comes from measurement, not estimation.

  • Coverage survey with heat map
  • Access points with roaming between them
  • Separate guest network with a portal
  • Coverage for warehouse, yard and shop floor

Cameras and access

Physical security

Cameras that hold up as evidence, not as decoration.

  • Survey of angles and blind spots
  • Retention period agreed in writing
  • Remote viewing with per-user accounts
  • Alerting when a camera stops recording
  • Card or biometric access control

How we quote

The build is measured in drops, not in feelings.

Every project comes out of the survey using this grid. You receive the number itemized, not a round total.

What finished looks like

What we hand over at closeout.

The installation we usually find

  • Switch resting on a shelf, no ventilation
  • Cables unlabeled, undrawn, uncertified
  • One flat network: cameras and accounting together
  • Wireless via three consumer routers
  • No record of what was bought or when warranty ends

What we leave

  • Rack mounted, ventilated, elevation documented
  • Every drop numbered and certified, with a report
  • VLANs separated and firewall rules written down
  • Wireless coverage measured, closeout heat map
  • Inventory with serials, warranties and purchase dates

Questions

Do we have to stop operations for the work?+

No. We work by zone and schedule any outage outside hours or on a weekend. In warehouses and plants we usually work between shifts. The schedule is agreed before we start and we hold to it.

Can we buy the equipment ourselves?+

Yes, and often you should. We give you the exact specification and you buy wherever you want. We charge for the design and the labor. We do not take hidden vendor commissions.

What about our existing cabling?+

We certify it before writing it off. Frequently half the plant is fine and only the terminations and the rack need redoing. Replacing everything by default is the easy answer for the installer, not for you.

Is there maintenance after the build?+

Optional. The build is handed over working and documented, with no obligation to sign a monthly agreement. If you add U1 Sustain, monitoring of that network is included at no extra cost.
