L-Acoustics K2 touring line array — SPL & coverage
A 40 x 25 m live event space needs confirmed SPL at the furthest listener position, not just a box count, before the touring line-array design is locked. The decision that matters here is whether the rated output of a single K2 element, once distance and drive level are accounted for, actually clears the target at the back of the room.

JBL Professional Control 25-1: SPL & coverage
A 20 x 12 m restaurant relying on background music needs a cabinet that stays intelligible at a 6 m listening distance without overpowering nearby tables. The real decision is whether the Control 25-1's rated output and dispersion give adequate SPL at that distance once drive level is set for comfortable background listening rather than full output.

JBL Professional CBT 70J-1 — SPL & coverage
A 20 × 12 m house-of-worship hall needs even, intelligible coverage out to a 12 m listener without a visible line-array or a forest of ceiling speakers. The design question is whether a single steerable column can hold usable SPL at the back of the room while keeping its vertical pattern off the ceiling and walls.

JBL Professional Control 26CT: SPL & coverage
A 15 x 10 m restaurant relying on background music needs to know whether a single ceiling cabinet keeps speech-and-music levels comfortable at typical table distances, not just how many boxes fit the floor plan on paper. The Control 26CT's rated output and dispersion answer both the SPL-adequacy question and the physical coverage-radius question for this specific cabinet before layout is finalised.

K-array Domino KF212: SPL & Coverage Preset
In a 25 x 18 m live event space, the practical question is not just how many Domino KF212 boxes to hang but whether the SPL reaching a listener at 12 m still lands in a usable range once drive is pulled back from full output. The 90 deg x 60 deg dispersion also has to be checked against the room's width before assuming a single hang covers the floor edge to edge.

K-array Tornado KT2: SPL & coverage at 6 m
A 20 x 12 m restaurant relying on background music needs the loudspeaker's rated output to translate into usable, even level at the listener's seat, not just at the cabinet face. For the Tornado KT2, a compact passive point-source box rated 100 dB SPL at 1 m, the real question is what level and coverage radius it actually delivers once distance and drive level are factored in.

K-array Mugello KH5: SPL & Coverage for Touring Rigs
A touring line array cabinet like the Mugello KH5 has to hold usable SPL across a large live-event floor while its horizontal and vertical dispersion decide how many listener positions actually stay inside the pattern. In a 40 x 25 m room, the real question is not just ”is it loud enough at the mix position” but whether the -6 dB coverage angle actually reaches the back and sides of the floor without over-driving the box.

Epson EH-LS12000B throw distance & placement
The EH-LS12000B is a premium home-cinema projector with a 1.35-2.84:1 zoom lens, so the real placement question is not whether it fits a room but how much slack that zoom range gives you to work around furniture, doorways, and seating. At a 120-inch 16:9 image (2.66 m wide), the difference between a fixed-throw and a zoom lens can decide whether the projector sits on a rear shelf or needs a ceiling mount closer to the screen.

Epson QB1000 throw distance & placement
A premium home cinema build wants a 120-inch 16:9 image, and the real question is how much room-length flexibility the Epson QB1000's zoom lens actually buys before the projector position is locked in. Placement decisions made before the throw distance is understood often end up either too close for a clean image or box the projector into a spot that conflicts with seating or joinery.

Epson Home Cinema 2350 throw distance & placement
Placing the Epson Home Cinema 2350 for a 120-inch image raises a genuine question: how much room-layout freedom does its zoom lens actually give, and is a lamp-based 2800-lumen projector bright enough for the space in mind. The answer depends on the model's specific 1.32-2.15:1 throw ratio, not a generic home-cinema rule of thumb.

Epson EH-LS800B throw distance & placement
An ultra-short-throw laser TV lives or dies on one decision: how close the cabinet can sit beneath the screen without the image clipping or distorting. For the Epson EH-LS800B at a 100-inch 16:9 image, that decision comes down to a throw distance of 0.35-0.35 m, which most living rooms and media walls can accommodate but which still needs to be checked against the specific console or shelf being used.

Sony VPL-XW7000ES throw distance & placement
A 120-inch 16:9 screen is the usual target size for a serious home cinema build, and the placement question is whether the room's real depth can accommodate this laser projector without forcing a false-ceiling relocation or a compromise on screen size. Because the VPL-XW7000ES carries a 1.35-2.16:1 zoom lens rather than a fixed-throw optic, the honest answer is a range, not a single number.

BenQ W5850 throw distance & placement
A dedicated home cinema room rarely has a projector position dictated purely by the screen wall; joists, a rear-seating credenza, or a rack cabinet often decide where the unit actually sits.

Optoma UHD55 throw distance & placement
The Optoma UHD55 is a native 3840x2160 home-cinema projector with a 1.21-1.59:1 zoom lens, so the real placement question is not ”will it fit” but ”how much room-layout freedom does the zoom actually buy back”. At a 120-inch 16:9 screen, the answer decides whether the projector sits on a rear shelf, a mid-room stand, or a ceiling mount closer to the screen.

Optoma CinemaX P2 - throw distance & placement
A living room wants a genuinely large image without a ceiling mount or a beam crossing the seating area, and the placement question for the CinemaX P2 is really a cabinet-position question, not a throw-distance question. At a 100-inch 16:9 screen the unit needs almost no room depth at all, so the real planning task shifts to the console and wall behind it.

Samsung LSP9T throw distance & placement at 100 inch
The Samsung LSP9T is built to sit on a low console immediately below the screen, so the real placement question is cabinet clearance and wall offset rather than a long throw run down the room. At a 100-inch 16:9 image, the difference between the unit sitting flush to the wall and a few centimetres proud of it is enough to shift focus and image squareness.

A 100-inch image from an ultra-short-throw laser TV lives or dies on centimetres, not metres: the Hisense PX3-PRO has to sit almost flush against the wall below the screen, so the placement question is cabinet clearance and screen alignment rather than a ceiling mount position. This preset opens the calculator on the PX3-PRO's fixed 0.22:1 throw ratio so that geometry is visible before any furniture or wall-unit decision is made.

Axis AXIS P3245-LV (2MP) — storage & retention
A fleet of Axis AXIS P3245-LV (2MP) dome cameras recording continuously for 30 days needs a head-end sized before the NVR is ordered, not after. Getting the per-camera daily footprint wrong at the planning stage means a disk array that either runs out of retention early or sits over-provisioned.

Axis Q6135-LE storage & retention (2MP, H.265)
A fleet of Axis Q6135-LE cameras recording continuously raises a straightforward but easy-to-underestimate question: how much usable storage does 30-day retention actually demand, and what class of head-end can hold it. Get the sizing wrong and a project either overspends on drive bays it does not need or runs out of retention days before the footage is reviewed.

Hanwha Wisenet XNB-9002 (4K) storage & retention
An 8MP camera at H.265 shifts the storage conversation from 'how many terabytes' to 'how many camera-days'. Once a fleet of Hanwha Wisenet XNB-9002 (4K) units is set to continuous recording at a 30-day hold, the daily footprint per camera becomes the number that decides the whole head-end.

Bosch FLEXIDOME IP starlight 8000i (4K) storage & retention
An 8MP camera recording continuously generates far more footage than a 2MP or 4MP unit, so a fleet-wide storage and NVR plan needs to be sized around the actual bitrate this model produces, not a generic rule of thumb. Getting the 30-day retention figure right up front avoids a mid-project scramble to add drives or swap the head-end once real footage volumes show up.

Uniview IPC2328SB-DZK-I0 (8MP) storage & retention
A fleet of Uniview IPC2328SB-DZK-I0 (8MP LightHunter) cameras generates far more footage per day than a 2MP or 4MP fleet, so the real decision is how much drive capacity and what NVR class a 30-day retention policy actually needs. Getting the storage math wrong at design stage means a mid-project drive upgrade or a head-end that cannot keep pace with continuous recording.

Vivotek FD9389-HM (5MP Dome) storage & retention
A fleet of Vivotek FD9389-HM 5MP dome cameras recording continuously will fill a head-end far faster than the same count in 2MP, so the storage math has to be worked out before the NVR and disks are chosen. The real decision is not the camera itself but how many days of footage the site needs to keep at that resolution, since retention is what drives the drive count.

Avigilon H6A Dome (8MP) storage & retention
A fleet of Avigilon H6A Dome (8MP) cameras generates far more footage per day than a standard-definition camera, so a 30-day retention target can quietly outgrow a modest NVR if storage is sized by guesswork. Getting the per-camera daily figure right before ordering hardware avoids either an under-sized head-end or an over-bought one.

Milesight AI Mini Dome 5MP: storage & retention
A fleet of Milesight AI Mini Dome 5MP cameras generates meaningfully more footage per day than a 2MP or 4MP line, so sizing the NVR and drive pool around guesswork risks either wasted spend or a retention window that runs out early. The real decision is how many days of continuous 5MP footage a given camera count must hold, and what head-end class that implies.

Reception / teller counter — identify a face at 4 m
A reception desk, bank teller line or pharmacy counter needs footage where a face is legally usable — not just 'someone was there'. The scene is a controlled ~4 m-wide choke-point, but the resolution still has to clear the IEC 62676-4 Identify threshold across the whole counter.

Warehouse aisle / yard — read a label or plate at 15 m
A warehouse aisle, loading yard or factory bay is a wide scene — often 12–18 m across — where the useful outcome is reading a carton label, a rack location or a vehicle plate, not just seeing that a forklift moved. Over that width, pixel density falls fast and 'more megapixels' has to be justified against the geometry.

A facilities lead planning an LED-and-controls retrofit on a 40,000 sq ft, 12-hour corporate office needs a defensible first-pass on how much annual electricity a coordinated upgrade could realistically address. The question is not a slogan but a number: how many kWh a year are actually in play before anyone commissions a detailed audit.

A single office floor's comms closet has to power a mix of Wi-Fi 6 access points, fixed cameras and desk phones from one PoE switch. The question is not whether any single port can drive its device — they all sit inside PoE+ limits — but whether one switch's shared power pool can carry the whole floor at once.

Dedicated cinema, 8 m room, reference scope — 164" screen
A dedicated 8 m-long, 5.5 m-wide, 3.2 m-high room is being built as a film-first cinema, and the screen has to feel immersive from the back row rather than merely large from the front. The decision is which viewing-angle tier and aspect the geometry can actually carry before the side walls or throw distance become the limit.
