The dust on the circuit board inside the NVR may cause a short circuit
after being exposed to moisture. Regularly clean the circuit board,
connectors, chassis, and chassis fan with a soft brush. If dirt is difficult
to remove, wipe it off with a neutral detergent diluted in water and
wipe it dry.
Do not use volatile solvents such as alcohol, benzene, or thinner when
cleaning the device. Do not use strong or abrasive cleaning agents. This
can damage the surface coating.
Please purchase the NVR dedicated hard drive recommended by the
equipment manufacturer from the formal channels to ensure the
quality and usage requirements of the hard drive.
Make sure that there is no threat due to uneven mechanical load.
Make sure that the video and audio cables have enough controls to
