ESD Prevention
To prevent electrostatic discharge (ESD) damage, ensure that:
 The appliance is well grounded. The grounding screw is properly grounded.
 Take dustproof measures for the equipment room.
 Maintain proper humidity and temperature levels.
 Do not disassemble the equipment without permission from the vendor, or
you may cause danger and void your warranty.
EMI Prevention
All possible electromagnetic interference (EMI) sources, external or internal, can
affect the security appliance by capacitance coupling, inductance coupling,
electromagnetic radiation, and common impedance coupling (including the
grounding system).
To prevent or reduce EMI:
 Take measures to protect the power system from power interference.
 It’s better to separate the floor where the security appliance is installed from
the grounding device and lighting-proof device of the power source.
