Place the detection device where the cheating actually happens, and inside its sensing range. For physical score-theft tools that means low and close — beside the coin door, near the control board, or against the back panel where the wiring harness and data cables live. For a result-integrity monitor watching for suspicious wireless or data activity, place it central to the cabinet's electronics with a clear line to that compartment. Get those two things right — the right zone, within range — and the unit does its job. Get them wrong and a perfectly good detector watches empty air.
I'm Engineer Wang. I've spent fourteen years on the attack-and-defense side of arcade hardware in Panyu, Guangzhou, and placement is the single thing that most often decides whether a customer's detector earns its keep. Here's how I tell operators to position each type.
Every unit has a working radius, and placement is meaningless if the target sits outside it:
Gen 1 Score Theft Detection Unit — roughly 1–1.5 m. This is a close-guard tool. It should almost be touching the cabinet it protects.
Gen 2 — about 2.5–3 m. More forgiving; can sit at the base of a cabinet and still cover it fully.
V5 Result Integrity Monitor — 5–8 m, built to watch a cluster.
K8 monitor — about 2.5–3 m, for single high-value cabinets like insured/lottery-type machines.
Whatever you place, the part of the machine you're worried about must fall inside that radius, with no thick metal sheet directly between the unit and what it watches.
Coin door and coin mechanism. Most physical theft and pulse/magnet attacks happen right at the coin acceptor. For a machine where the coin path is the weak point, set the unit low, near the coin door, on the inside ledge of the lower compartment if there is one.
Control board and joystick/button input. Score-theft via jumper cards, harness taps, or board manipulation lives in the electronics bay. Position the detector so the control board and its cabling are well within range — typically the rear or side of the cabinet, behind a locked panel.
Data cables and the back panel. Result leakage and hidden wireless activity show up around the COM ports, ribbon cables, and the board's data lines. A V5 or K8 monitor wants a central, unobstructed position relative to that compartment so it can pick up the 2.4G/Bluetooth/WiFi and data-channel anomalies it's listening for.
Tabletop fish games and pusher cabinets. These have a wide attack surface and players crowd close. A Gen 2 unit at the base, or a V5 covering several tables from a central post, works better than trying to guard each station individually.
There's a tension every operator feels: you want the unit out of sight so a cheater doesn't simply remove it, but it can't "see" through a steel wall. My rule of thumb:
Concealed is good; smothered is bad. Behind the lower bezel, on an internal shelf, inside the locked cash compartment — all fine. Wrapped in a metal box or buried under a stack of prize cartons — not fine.
Keep one clear face toward the target. ABS plastic, wood, and acrylic don't block the unit; a continuous sheet of metal between unit and target does. If the cabinet is all-steel, put the unit inside the same compartment as the electronics rather than outside the shell.
Protect the power. If a customer can reach the plug, your placement doesn't matter. Run the lead to an internal outlet behind a locked panel where possible.
The recurring ones I get called about: a Gen 1 unit set a full meter past its range "to keep it out of the way," a monitor placed outside the metal electronics cage so the casing blocks it, and a unit powered from a wall socket a player can yank. All three are easy to avoid once you know to look for them.
Placement is only step one of getting a unit live — the rest of the no-tools install is in how to install an anti cheat device without wiring, and the full deployment flow sits on the setup and operation overview. If you're covering a packed floor and wondering whether one well-placed unit can guard several cabinets, that math is in covering multiple machines with one detection unit.
