operation of the DVR, and even damage the DVR. For long-term stable operation of the
DVR, brush off the dust on the circuit board, connectors, fans, and DVR case regularly.

protect the DVR from damage caused by static or induced voltage.

damage these ports.

easily damage the video output circuit in DVR.
