Restaurant POS cabling and network for retail fit-outs

Most restaurant and retail fit-outs reach the millwork install before anyone asks where the network cable goes. By then the counter is built and the ceiling is closed, so drops that should have taken a week at rough-in become surface raceway on a finished wall. Restaurant POS cabling and network design is not difficult work, but it has to happen earlier in the schedule than most tenant improvement programs assume.

Why POS terminals, kitchen screens and payment devices want a wired drop

Anything that sits in one place and takes money should have a cable to it. Wireless is a shared medium: once the room fills, every guest phone competes for the same airtime as the till. A terminal commissioned on a quiet Tuesday afternoon behaves differently at 7 pm on a Friday with 90 people in the room.

The failure mode is what makes the drop worth paying for. A dropped association mid-transaction produces a queue, a manual re-key, and a staff member telling a customer the system is down. On a Cat6 drop the path does not roam, re-associate or contend.

Wire the till stations, kitchen display screens, ticket printers, payment docks, cameras, access points and menu boards. Even tablet-based POS usually has a dock or base station that takes a cable. Where a device is wireless-only, run a cable to an access point over that counter and a spare into the cabinet for whatever replaces the device in three years.

Planning restaurant POS cabling and network drops before millwork is built

Mark drop locations on the millwork shop drawings, not only on the reflected ceiling plan. Cable has to reach the inside of the counter base cabinet through a sleeve the joinery shop knows about, and stay accessible once the cabinets are set. Millwork drawn without that detail comes back as a sealed box with no way in.

Plan positions, not areas.

Position Drops to plan
Each till 2–3: terminal, receipt printer, payment dock
Kitchen pass or expo 2 per station: display screen, ticket printer
Bar 2–3: terminal, printer, music source
Server stations and host stand 2 each
Patio 2–3: outdoor AP, camera, seasonal till
Each ceiling AP 1–2
Back door and receiving 2: camera, intercom or door hardware
Back office 4+ and the rack: router, switch, recorder, music

Pull a spare drop at every counter and pass position: a second cable at rough-in costs a fraction of fishing one in later. Leave a service loop and a permanent label at both ends, and photograph every wall before drywall — the cheapest as-built record you will produce.

Coordinate with the electrician so the receptacle and the data drop land in the same cabinet, and cross line-voltage at right angles rather than running alongside it. The same structured cabling discipline used in a multi-family building applies here, on a much shorter schedule.

Music and paging

Music and paging are distribution problems, so design them alongside the data drops. Zone them first — dining, bar, patio and back of house rarely want the same volume — and confirm patio hours with the municipality. A 70 V system runs one pair to a chain of ceiling speakers; networked speakers take a Cat6 drop each and keep zoning in software. The amplifier and paging input belong in the rack with the switch and recorder.

Wi-Fi design for a room full of people and metal

One router in the back office does not cover a restaurant. Everything between it and the dining room is close to a worst case for 5 GHz: an insulated walk-in wall, stainless prep tables, a hood, and a room that fills with people who are mostly water. A survey run at 3 pm in an empty room is not the room you operate in.

Design coverage from the ceiling, in the space, with several modest access points rather than one loud one. The client is the weak side of the link: a phone can hear a powerful AP that cannot hear the phone back.

  • One AP per distinct area — dining, bar, patio, kitchen, back of house — not a count per square metre.
  • Walk-in coolers are effectively opaque; if staff scan inventory inside, that space needs its own coverage.
  • The patio takes an outdoor-rated AP mounted outside, not an indoor unit aimed through coated glazing.
  • In a strip mall you share 2.4 GHz with every neighbour across three non-overlapping channels. Keep what matters on 5 GHz.
  • Exposed-structure ceilings leave the AP visible: agree mount and colour with the designer early.

Keep payment traffic off the guest network

Guest Wi-Fi, POS, cameras and building systems belong on separate networks — separate SSIDs and VLANs, not one flat network with a different password. A guest device, or a staff phone, should have no path to a payment terminal, and a rate limit on the guest side stops someone downloading a film from starving a card transaction.

Obligations attached to card processing come from your payment processor and the card brands, and depend on how you accept payment. Ask them what applies, and build the segregation regardless: straightforward at install, awkward to retrofit once live.

Camera positions: till, back door, receiving and storage

The cameras that earn their cost are over each till, on the back and delivery doors, and over receiving and stock. Everything else is coverage; those are evidence.

A till camera has to see the drawer, the hands and the customer's face; from the far corner of the room it produces a person-shaped blur. Ask your POS vendor whether transaction data can be overlaid on the recording — that is how voids, refunds and no-sales get investigated.

The back door is the highest-risk opening in a food business: it gets propped for deliveries and breaks. A camera plus a monitored contact tells you when it is open and for how long; where the door also needs credentialled entry it belongs in the access control scope. Receiving coverage settles short-delivery disputes as often as it catches theft.

Floor cameras are for incidents and liability claims, so a wide view is enough. Retention drives recorder sizing, so decide how many days you need before buying hardware, and keep the recorder somewhere lockable — one on a back counter walks out with the evidence. Layouts for leased units are covered in our surveillance work.

Recording in a workplace carries privacy obligations in BC. Cameras should not cover washrooms, change or break areas, staff and customers generally need notice, and both positions and retention are worth reviewing with your employer counsel or the landlord first.

What a commercial kitchen does to cable and devices

Grease-laden air decides equipment selection in the back of house. It films every surface on the cook line, works into keypads, clouds camera domes and, with heat above it, makes plastic housings brittle. Anything specified for an office ceiling will not last there.

Choose devices you can wipe down: sealed and gasketed housings, stainless or wipeable faceplates, and commercial screens rated for the temperature they sit in. A consumer television over the pass fails on heat and grease, usually inside a year.

  • Keep network devices out of the hood's immediate zone. Clearances around hoods and suppression equipment are the mechanical and fire trades' scope and subject to the authority having jurisdiction.
  • Run cable in conduit or on tray above a kitchen ceiling rather than loose across it, sleeve anything passing through a hard lid, and land wet-area drops in a sealed enclosure with a gland rather than an open faceplate.
  • Give the switch a ventilated location. PoE devices generate heat, and a hot cupboard beside the dish pit shortens the life of everything in it.
  • Cable jacket rating depends on the space and its plenum treatment, and that call sits with the authority having jurisdiction. Confirm locally before ordering.

Sequencing low-voltage against a fixed fit-out schedule

The landlord's turnover date and rent commencement do not move, so low-voltage gets squeezed at exactly the point where it can no longer be roughed in. Treat two items as long-lead from the day the lease is signed.

The first is the internet circuit. Bringing service into a leased unit can involve landlord consent, a building entry point and the carrier's own crew, and it is the most common reason a site opens without a working network. The second is the millwork drawing set, where drop locations get captured.

Fit-out stage Low-voltage action
Lease signed Order the circuit. Confirm the demarcation point and the path to the rack.
Design and permit Mark drops on ceiling and millwork drawings. Fix the rack location.
Demolition and framing Sleeves and back-boxes in framed walls before drywall.
Rough-in Pull cable, leave service loops, label both ends, photograph the walls.
Millwork install Feed drops into cabinets as they land.
Ceilings and finishes Mount APs and cameras, terminate, test, record results.
Equipment and training POS vendor commissions terminals. Verify network separation.
Opening week Test at capacity, not in an empty room.

The stage most often missed is millwork install. Cabinets arrive on a truck and get set in a day; the cable goes in as they are placed, or it does not go in at all. Somebody has to be on site that morning.

What to do next

Before your next drawing set goes to the millwork shop, mark every till, screen, printer, AP and camera position on it, order the internet circuit, and decide where the rack lives. Those three decisions cost nothing on paper and are the expensive ones to reverse. Orbit Automation can walk a restaurant or retail fit-out in Metro Vancouver or the Fraser Valley with your GC and mark up drop locations before the walls close.

FAQ

Questions we get asked.

Should restaurant POS terminals be wired or on Wi-Fi?

Wire them. A POS terminal, a kitchen display screen and a receipt printer all fail in the same expensive way on wireless: mid-transaction, during the busiest hour, when the room is full of phones competing for airtime. Wi-Fi belongs to guests and to devices that genuinely move. Anything that sits in one place and takes money should have a cable to it.

How many network drops does a restaurant need?

Count the fixed device positions rather than the square metres: each till, each kitchen display, each printer, each ceiling access point, each camera and the back-office rack. Then add a spare drop at every counter and pass position. Pulling a second cable during rough-in costs a small fraction of fishing one through finished millwork and a tiled backsplash later.

Can guest Wi-Fi and the POS share the same network?

They should not. Guest devices, payment terminals, cameras and building systems belong on separate networks with separate credentials, not on one flat network with a shared password. Segregating payment traffic is sound practice regardless of who asks for it, and it also stops a guest streaming video from taking bandwidth away from a card transaction. Obligations attached to card processing come from your payment processor and the card brands, so confirm the specifics with them and with your POS vendor.

When should low-voltage be installed during a restaurant fit-out?

Cable is pulled at rough-in, before drywall and before ceilings close, which in most tenant improvement schedules is earlier than anyone plans for. Two items have to start sooner still: the internet circuit, ordered as soon as the lease is signed, and the drop locations, marked on the millwork shop drawings before the cabinets are built. Devices are mounted, terminated and tested after finishes.

Where should cameras go in a restaurant or retail unit?

The positions that earn their cost are over each till, on the back and delivery doors, and over the receiving and stock areas. A till camera should be close enough to see the drawer, the hands and the customer's face rather than the top of a cashier's head. Recording staff at work carries privacy obligations in BC, so camera positions and retention should be reviewed with your employer counsel before installation.
