Arcade machines represent significant investments for operators, making hardware security paramount. Preventing tampering requires a multi-layered approach combining physical and digital safeguards. Physical security measures form the first line of defense. Specialty security screws, such as Torx, spanner, or custom head designs, prevent casual access to internal components. High-security locking systems, including cam locks and deadbolts, secure cabinet doors and access panels. Tamper-evident seals applied to screw heads and panel edges provide visible evidence of unauthorized entry. For internal protection, component epoxy potting encases critical boards in hardened resin, protecting against physical modification while allowing heat dissipation. Wire conduit and loom protect wiring harnesses from cutting or splicing. Digitally, environmental monitoring systems track cabinet openings through magnetic sensors, logging events to internal memory or cloud platforms. Motion-activated internal cameras can capture images during unauthorized access. Secure boot processes and firmware checksums verify software integrity at startup, preventing malicious code injection. Cash box security receives special attention, with separately locked compartments, weight sensors that trigger alerts if removed improperly, and bill validator anti-tamper mechanisms. For connected machines, remote monitoring systems provide real-time alerts for door openings, power disruptions, or geographic movement beyond established boundaries. Regular security audits, combined with visible deterrent signage indicating surveillance and tamper prosecution policies, complete a comprehensive anti-tampering strategy. The most effective approach integrates multiple methods, creating overlapping layers of protection that deter both opportunistic vandalism and sophisticated theft attempts.
