Fault phenomenon
Reason / solution
No self-test after
power supply,
no image output
There is a broken line in the circuit / find breakpoints,
rewiring.
Low supply voltage / Replace the power adapter to
increase the output voltage.
Self-test exception
Low supply voltage / Replace the power adapter to
increase the output voltage.
Equipment control is
normal,
image instability
Poor video circuit contact / troubleshooting, rewiring.
Access device exception / replacement access device
Equipment control is
normal,
image instability
Network line bad contact / dismantling bad point,
re-wiring.
Access to computer performance is insufficient, take up
CPU usage / lower stream and resolution
Lack of network bandwidth / replacement of industrial
Gigabit switches
Access decoder performance / replacement of
high-performance decoder
Self-test normal, can
not control
Wrong wiring / rewiring
Set the baud rate, protocol, address and device mismatch /
screen configuration according to device parameters
Repeated restart
Insufficient supply voltage or voltage instability / to
ensure that the input device voltage stability
