Maintenance
Damped dust on the PCB board will cause a short circuit and will do
something wrong to the DVR or damage it. For long-term stability of the
DVR, regularly brush the circuit boards, connectors, fans and chassis to
remove dust.
Please ensure the project is well-grounded, so images, audio signal will
not be disturbed. At the same time, we can protect the DVR from static
or inductive voltage damage.
