This is a planning conversation, not a bill of quantities, not a compliance determination and not a design. It sets out what has to be decided and which drawings those decisions will need. Quantities, specifications and any statutory position come from the appointed consultants and from a site-specific review.

How these systems depend on each other

• Camera surveillance depends on Network switching — Cannot work without it. An IP camera is a network device. With no switch port and no address it produces no picture at all, anywhere.
• Camera surveillance depends on Structured cabling — Cannot work without it. Every camera position is a cable run back to a node, and that run is drawn with the rest of the cable plant or it is improvised on site.
• Camera surveillance depends on Electrical supply — Cannot work without it. Whether it comes down the data cable or from a local supply, the camera has to be powered by something somebody has drawn.
• Camera surveillance depends on Power over Ethernet — Usual, not universal. Most cameras take power from the same cable that carries the picture, which is why the camera count lands on the switch budget. Local low-voltage supplies are still used where there is no suitable port.
• Camera surveillance depends on Recording and retention — Usual, not universal. Live-only monitoring exists, but nearly every installation records. How long footage is kept is the decision that sizes the platform, and it is a business decision before it is an engineering one.
• Camera surveillance depends on Rack and equipment room — Usual, not universal. The recorder, the switch and the licences land in a cabinet. Small estates run from a wall-mounted enclosure instead, which is a legitimate answer and a different one.
• Camera surveillance depends on Uninterruptible power — Only in certain cases. Only where the client expects to keep seeing and recording through a mains interruption. Cameras, the switch feeding them and the recorder are three separate loads. Protecting one and not the others produces a system that stops anyway.
• Camera surveillance depends on Containment and cable pathways — Cannot work without it. Camera cabling needs a route. Where that route was drawn for the data cabling alone, the cameras arrive as an unplanned addition to a full tray.
• Access control depends on Door hardware — Cannot work without it. The reader and the controller only make a decision. The lock, the closer, the frame and the leaf are what physically hold or release the door, and they are usually somebody else's package.
• Access control depends on Structured cabling — Cannot work without it. Each controlled door is a cable run to a controller, and door positions move later in the design than cable schedules like.
• Access control depends on Electrical supply — Cannot work without it. Controllers, readers and locks are all powered, and the lock is often the load nobody counted.
• Access control depends on Network switching — Usual, not universal. Networked controllers are the usual arrangement because they let credentials be issued and revoked centrally. Standalone controllers on a local bus are still specified on small door counts.
• Access control depends on Containment and cable pathways — Cannot work without it. Door cabling runs above ceilings and down frames, and the route has to exist before the frames are set.
• Access control depends on Uninterruptible power — Only in certain cases. Only where the client needs controlled doors to keep behaving predictably through a mains interruption. Without a supply, controllers stop making decisions and the doors sit in whatever state their hardware defaults to.
• Access control depends on Fire detection — Expert-held. What a controlled door on an escape route does in an emergency is set by the project's fire strategy and the authority having jurisdiction. It is not derived from a door schedule and this planner does not determine it. PROJECT-SPECIFIC VERIFICATION REQUIRED before door hardware is specified or ordered.
• Wi-Fi depends on Structured cabling — Cannot work without it. An access point is a wired device with a radio on the end. Every one of them is a cable run to a ceiling position that has to be agreed with the architect.
• Wi-Fi depends on Network switching — Cannot work without it. Access points terminate on switch ports. The port count and the wireless design are the same conversation, held twice on most projects.
• Wi-Fi depends on Power over Ethernet — Usual, not universal. Access points are normally powered by the switch, which is what turns a coverage plan into a power budget. Local injectors are used where a suitable switch is not present.
• Wi-Fi depends on Electrical supply — Cannot work without it. The power arrives at the access point one way or another, and the switch that supplies it is itself a load in the equipment room.
• Wi-Fi depends on Rack and equipment room — Usual, not universal. The switching and any controller sit in a cabinet on the floor or in the equipment room. Small deployments run from cloud-managed access points with no local controller at all.
• Wi-Fi depends on Internet or wide-area uplink — Only in certain cases. Only where the wireless network is expected to carry internet or cloud traffic rather than local traffic only. Wireless coverage and internet access are different things, and a guest expecting the second will call the first broken.
• Wi-Fi depends on Mounting and fixing — Cannot work without it. The ceiling finish decides what an access point can be fixed to, and a plasterboard raft, an exposed soffit and a stretched fabric ceiling are three different answers.
• Telephony depends on Network switching — Cannot work without it. Voice handsets are network devices on the same switches as everything else, which is convenient until the network is being planned without them counted.
• Telephony depends on Structured cabling — Cannot work without it. Each handset position is an outlet, and handset positions are decided by furniture layouts that are often not final when the cabling is.
• Telephony depends on Power over Ethernet — Usual, not universal. Handsets are usually powered from the switch so a desk needs no extra adaptor. Some deployments use local supplies instead.
• Telephony depends on Internet or wide-area uplink — Only in certain cases. Only where outside calls are carried over a data connection rather than a local line. If calls leave the building over a data path, then the state of that path is the state of the phone system.
• Telephony depends on Uninterruptible power — Only in certain cases. Only where voice has to stay available through a mains interruption. An IP handset is only as available as the switch it hangs off and the platform behind it.
• Telephony depends on Rack and equipment room — Usual, not universal. Gateways and any on-premises platform live in a cabinet. Fully hosted deployments keep almost nothing on site.
• Background music and paging depends on Loudspeakers — Cannot work without it. The loudspeaker layout is the system. Where the ceiling grid, the lighting and the loudspeakers are drawn separately, one of them moves on site.
• Background music and paging depends on Amplification — Usual, not universal. Distributed loudspeakers are usually passive and driven from a central amplifier. Powered loudspeakers on a networked source are a real alternative on smaller layouts.
• Background music and paging depends on Electrical supply — Cannot work without it. Amplification is a real electrical load in the rack position, and it is often sized after the electrical drawings are issued.
• Background music and paging depends on Containment and cable pathways — Cannot work without it. Loudspeaker cabling runs the length of every zone and needs its own route, kept apart from cabling it should not share a containment with.
• Background music and paging depends on Rack and equipment room — Usual, not universal. Amplification and sources land in a cabinet, and amplification is one of the warmer things in it.
• Background music and paging depends on Audio processing — Sometimes specified. Zone processing helps where zones differ a lot in size or noise. A single-zone music system does not need it and is not improved by it.
• Background music and paging depends on Content and source — Usual, not universal. Music needs something to play, and who holds the right to play it in a commercial space is a question the client answers rather than the installer. An announcement-only system is the real exception: its source is the microphone at the paging station, and there is no programme material to license.
• Digital signage depends on Display or screen — Cannot work without it. The screen is the system, and whether it is read while walking past or while standing still changes the size before the model.
• Digital signage depends on Content and source — Cannot work without it. A screen with nobody appointed to update it is a screen showing last season's message. Who writes the content is decided at design stage or it is not decided at all.
• Digital signage depends on Mounting and fixing — Cannot work without it. The screen hangs on something, and a feature wall built from plasterboard on a light frame is the classic late discovery.
• Digital signage depends on Electrical supply — Cannot work without it. Power behind the screen, at the height the screen is actually at, is a coordination item and not an assumption.
• Digital signage depends on Network switching — Usual, not universal. Screens are normally updated over the network. Players that run from local storage exist and are still specified where no network reaches.
• Digital signage depends on Structured cabling — Usual, not universal. Where the screen is updated over the network it needs an outlet behind it, which is a different position from the power outlet only by accident.
• Fire detection depends on Electrical supply — Cannot work without it. Detection equipment is powered equipment and appears in the electrical coordination like anything else. Nothing about how it is supplied is settled here.
• Fire detection depends on Containment and cable pathways — Cannot work without it. Detection cabling needs a route, and the route is coordinated with the other services early so it is not competing for the same tray later. What that cabling must be, and how it is segregated, comes from the fire scheme.
• Fire detection depends on Automation and building controls — Expert-held. Whether detection signals do anything to building plant is set by the project's fire strategy and the authority having jurisdiction. It is not derived from a controls points list and this planner does not determine it. PROJECT-SPECIFIC VERIFICATION REQUIRED.
• IPTV and in-room television depends on Network switching — Cannot work without it. Television over the building network is network traffic, and it behaves differently from everything else on the switch.
• IPTV and in-room television depends on Structured cabling — Cannot work without it. Every screen position is an outlet, and screen positions in rooms are set by the interior designer rather than the cable schedule.
• IPTV and in-room television depends on Content and source — Cannot work without it. Channels come from somewhere, and the rights to show them in a commercial building belong to the client.
• IPTV and in-room television depends on Display or screen — Cannot work without it. The screen is what the guest actually experiences, and it is often chosen for the room before anyone asks what will drive it.
• IPTV and in-room television depends on Internet or wide-area uplink — Only in certain cases. Only where channels or streaming services are carried from outside rather than from a local head-end. Where the channels come from outside the building, the outside path is part of the television system.
• IPTV and in-room television depends on Rack and equipment room — Usual, not universal. The head-end and its licensing sit in a cabinet, usually the same one everything else is competing for.
• Automation and building controls depends on Electrical supply — Cannot work without it. Controls sit between the supply and the thing being controlled, so the electrical design and the controls design are the same drawing seen twice.
• Automation and building controls depends on Containment and cable pathways — Cannot work without it. Field devices are distributed everywhere by definition, and their routes are the ones most often assumed to be somebody else's.
• Automation and building controls depends on Network switching — Usual, not universal. Head-ends and modern controllers normally sit on the network. Field buses that never touch it are still widely used.
• Automation and building controls depends on Rack and equipment room — Usual, not universal. The head-end and its interfaces need a home, and it is usually the same cabinet everything else wants.
• Automation and building controls depends on Structured cabling — Only in certain cases. Only where the chosen controllers use the building's data cabling rather than a dedicated field bus. Some controls ride the data cabling and some run on their own bus, and the two are budgeted by different people.
• Sound reinforcement depends on Loudspeakers — Cannot work without it. Coverage is decided by where loudspeakers can physically go, which is a ceiling and rigging conversation with the architect.
• Sound reinforcement depends on Amplification — Usual, not universal. Most loudspeakers are passive and need external amplification. Active loudspeakers carry theirs inside and need none, which changes the rack and the electrical load.
• Sound reinforcement depends on Audio processing — Only in certain cases. Only where the system has several zones, several live microphones, or delay and equalisation to manage across a difficult room. Processing is not automatic. A single-source, single-zone system does not need it and is not made better by adding it.
• Sound reinforcement depends on Microphones — Usual, not universal. Speech reinforcement needs microphones and their positions constrain everything else. A programme-playback-only system needs none.
• Sound reinforcement depends on Containment and cable pathways — Cannot work without it. Loudspeaker and microphone cabling needs routes that were drawn for it, and rigging positions above a hall are decided with the structural engineer.
• Sound reinforcement depends on Electrical supply — Cannot work without it. Amplification is a genuine load at the rack position, and how it is earthed decides whether the system hums.
• Sound reinforcement depends on Rack and equipment room — Usual, not universal. Amplification, processing and sources land in a cabinet near the room they serve. Small active systems can live behind a panel instead.
• Sound reinforcement depends on Room geometry — Cannot work without it. How reverberant a room is depends on its shape and its finishes, and both are settled by others. A system designed before the finishes are known is designed against a guess.
• Projection depends on Projection surface — Cannot work without it. The surface is half the system, and whether it stays visible when unused is an interior decision with a technical consequence.
• Projection depends on Room geometry — Cannot work without it. Throw distance, ceiling height and the seated sightline decide the lens and the mounting position before any product is chosen. Where the architecture is fixed first, projection has to fit it.
• Projection depends on Mounting and fixing — Cannot work without it. The projector hangs from structure or a bracket that has to be coordinated with the ceiling, the lighting and access for a lamp or filter change.
• Projection depends on Signal transport — Cannot work without it. The projector is rarely near the source, so the run between them is a design item rather than a cable off a shelf.
• Projection depends on Electrical supply — Cannot work without it. A supply at the projector position, which is usually a ceiling position with no other reason for a socket to be there.
• Projection depends on Control and user interface — Usual, not universal. Most rooms want the projector, the screen and the lighting to move together on one press. A simple room can be operated with separate controls.
• LED display wall depends on Electrical supply — Cannot work without it. A modular wall is a substantial and continuous electrical load, and it is one of the few AV items that genuinely changes the electrical design.
• LED display wall depends on Video processing — Cannot work without it. A wall is a grid of modules, not a screen. Something has to turn an incoming picture into the pixel map that drives them.
• LED display wall depends on Signal transport — Cannot work without it. The picture has to reach the processor from wherever it is made, and that route is usually longer than anyone assumed at concept stage.
• LED display wall depends on Content and source — Cannot work without it. A wall is built at one pixel geometry and content is made at another. Agreeing that early is the difference between a sharp wall and a stretched one.
• LED display wall depends on Structure and service access — Cannot work without it. The frame carries real weight and has to be fixed to real structure. Whether the wall is serviced from the front or the back has to be settled before it is built, not after.
• LED display wall depends on Network switching — Usual, not universal. Control and monitoring normally sit on the network so the wall can be driven and checked remotely. Locally driven walls exist.
• LED display wall depends on Uninterruptible power — Only in certain cases. Only where the wall carries live content that must not drop during an event. A wall that goes dark mid-event is a different failure from a wall that goes dark overnight.
• Meeting-room and conferencing AV depends on Display or screen — Cannot work without it. There is nothing to look at otherwise. The size is set by the distance from the furthest seat, which means the furniture layout has to be settled first.
• Meeting-room and conferencing AV depends on Microphones — Cannot work without it. A call the far end cannot hear is not a call. Microphone placement is the single biggest determinant of whether people are willing to use the room.
• Meeting-room and conferencing AV depends on Loudspeakers — Cannot work without it. The room has to hear the far end, and the ceiling that carries the loudspeakers is coordinated with lighting, detection devices and air terminals.
• Meeting-room and conferencing AV depends on Room camera — Cannot work without it. The far end has to see the room, and where the camera can go is a furniture and sightline question before it is a product question.
• Meeting-room and conferencing AV depends on Conferencing platform — Cannot work without it. The room is built around whichever service the organisation actually runs meetings on today. Choosing hardware before that is settled is how rooms end up unused.
• Meeting-room and conferencing AV depends on Network switching — Cannot work without it. The room joins the call over the network, and a room codec is a device somebody has to have counted on the switch.
• Meeting-room and conferencing AV depends on Structured cabling — Cannot work without it. Table boxes, floor boxes and the display position all need cable routes agreed before the slab is poured or the joinery is made.
• Meeting-room and conferencing AV depends on Electrical supply — Cannot work without it. Power at the display, at the table and at the rack position. The table one is the one that gets left off the electrical drawing.
• Meeting-room and conferencing AV depends on Control and user interface — Usual, not universal. Most rooms want one obvious way to start a meeting. A small huddle room can genuinely run from the laptop and the display's own remote, and adding control to it makes it worse.
• Meeting-room and conferencing AV depends on Audio processing — Only in certain cases. Only where the room has several microphones, or open-microphone pickup that needs echo cancellation and mixing across a live room. Processing is not a default line item. An all-in-one conferencing bar does its own echo cancellation and mixing internally, and specifying separate processing beside it buys nothing.
• Meeting-room and conferencing AV depends on Mounting and fixing — Cannot work without it. The display and camera hang on something, and a partition wall is not always that something.
• Rack and equipment room depends on Electrical supply — Cannot work without it. The room's supply is the sum of everything anyone puts in it, which is usually more than the first list.
• Rack and equipment room depends on Heat removal — Only in certain cases. Only where the installed load and the room's own ventilation cannot hold the cabinets inside the equipment's stated operating range. Equipment turns its power into heat inside a closed cabinet, and where the room cannot shed it the equipment shortens its own life.
• Rack and equipment room depends on Containment and cable pathways — Cannot work without it. Everything arrives as cable, and the entry point, the bend radius and the tray above the cabinets are all drawing items.
• Rack and equipment room depends on Uninterruptible power — Usual, not universal. Most equipment rooms protect at least the network and the recording. Which loads are on that list is a decision the client should make explicitly.
• Uninterruptible power depends on Electrical supply — Cannot work without it. The protected supply is fed from the ordinary one, and the changeover arrangement belongs to the electrical design.
• Uninterruptible power depends on Heat removal — Only in certain cases. Only where the batteries sit in an enclosed space whose temperature would otherwise run above the battery's rated range. Battery life falls away as the room gets warmer, so a runtime figure quoted for a cool room is not the runtime a hot cupboard gives.
• Network switching depends on Structured cabling — Cannot work without it. A switch port is only useful if a cable reaches something. The port count and the outlet count are the same number, arrived at separately on most projects.
• Network switching depends on Rack and equipment room — Cannot work without it. Switches are rack equipment. Where they go decides cable lengths, and cable lengths decide where they can go.
• Network switching depends on Electrical supply — Cannot work without it. A switch that powers devices draws what it delivers plus its own consumption, and that is a bigger number than the label on the front.
• Network switching depends on Power over Ethernet — Only in certain cases. Only where cameras, access points, readers or handsets are to be powered from the switch rather than locally. Powering devices from the switch is a budget, not a checkbox, and the budget is set by what is plugged in.
• Network switching depends on Internet or wide-area uplink — Only in certain cases. Only where systems on this network have to reach the internet or a hosted service. A network can be entirely internal and still be a network. What it must reach is a client decision.
• Network switching depends on Uninterruptible power — Only in certain cases. Only where any system on this network has to keep working through a mains interruption. Everything riding on the network stops when the switch does, which makes the switch the load people most regret leaving unprotected.
• Structured cabling depends on Containment and cable pathways — Cannot work without it. Cable needs a route with room in it. Containment sized for today's count is the most common reason a later addition costs more than it should.
• Structured cabling depends on Rack and equipment room — Cannot work without it. Every run terminates somewhere, and the room that receives them has to have been sized for the panels as well as the equipment.

What these systems pull in

• Electrical supply. A circuit at the right place, coordinated with the electrical contractor rather than assumed.
• Power over Ethernet. Power delivered down the data cable by the switch, so the device needs no local supply.
• Recording and retention. Where footage is written, how long it is kept, and who may take a copy of it.
• Internet or wide-area uplink. The path out of the building, and what stops working when it is down.
• Containment and cable pathways. Tray, conduit and risers — drawn once for every system together, or fought over on site.
• Heat removal. Equipment in a closed cabinet turns its power into heat, and the heat has to leave.
• Door hardware. The lock, closer, frame and leaf. The reader decides; this is what actually holds or releases.
• Loudspeakers. Where sound comes from, and therefore where the ceiling has to be coordinated.
• Amplification. Driving passive loudspeakers. Active loudspeakers carry their own and need none.
• Audio processing. Mixing, echo cancellation, delay and equalisation, where the room and the sources need it.
• Microphones. How the room is heard, and the single biggest determinant of whether a call is bearable.
• Room camera. How the far end sees the room, which is a furniture and sightline question before it is a product one.
• Display or screen. The surface people read, sized against the furthest seat rather than the wall.
• Conferencing platform. The service the organisation already runs its meetings on. The room is built around it.
• Control and user interface. What somebody touches to start the room, and how many steps that takes.
• Signal transport. Getting picture and sound from where they are made to where they are shown.
• Video processing. Turning an incoming picture into the pixel map that drives a modular display.
• Content and source. What is actually shown, at what resolution, produced by whom, and updated how often.
• Structure and service access. What carries the load, and how somebody reaches the back of it two years later.
• Projection surface. The screen or wall the image lands on, and whether it has to disappear when unused.
• Mounting and fixing. What the equipment is fixed to, checked against what that surface can actually hold.
• Room geometry. Ceiling height, room length and seated sightlines — settled by the architect, not by the AV supplier.
