Based on the previously mentioned periodic maintenance requirements for mobile surveillance cabinets, the necessary tools and materials can be categorized by their specific functions:
Basic Hand Tools
Assembly/Disassembly Tools:A full set of Phillips and flat-head screwdrivers, an adjustable wrench, needle-nose pliers, diagonal cutters, wire strippers, and crimping tools; these are required to handle fasteners of various specifications found on the cabinet.
Auxiliary Tools: Anti-static wrist strap, voltage tester (test pen), and flashlight; these help prevent static damage to electronic components and ensure safety when working in low-light conditions.
Testing and Diagnostic Tools
Core Instruments: Digital multimeter; used to measure voltage, check circuit continuity and insulation, and rapidly troubleshoot power supply issues.
Auxiliary Equipment: Network cable tester and "Engineering Tester" (CCTV tester); used to verify network connectivity and video signal quality for the surveillance equipment inside the cabinet.
Cleaning and Protective Materials
Cleaning Consumables: Dust-free wipes, lens cleaning paper, anhydrous alcohol (concentration ≥99%), microfiber cloths, and compressed air dusters; used to remove dust and grime from lenses, circuit boards, and heat dissipation vents.
Protective Consumables: Insulating electrical tape, waterproof self-adhesive tape, anti-rust paint, and desiccant; used for insulating wiring, preventing cabinet rust, and controlling moisture inside the cabinet.
