General Failure Analysis
（
1
）
After power on, no motion and no image
. At this time should check
whether the normal power supply, if it is 24V AC power supply,
power supply with the carrying capacity is adequate, and have to
view the amount of current, voltage should not just look at; if the
DC power supply, check whether the next anti-polarity.

Self test is exceptional, there is image but with motor noise “wu”
May
inspect the installation of the camera level, the availability of tilt, or
whether the lack of power supply current.

）
Normal self-testing, but completely beyond the control of the
speed dome camera. Should inspect and check the
communication protocol, baud rate and ID, and to ensure that
communication lines to connect to normal. RS-485 is a polarity,
that is, check the "+" and "-" whether the anti-access.

Power on, Self testing normal, but no images, should check video
line, and if the video connections are ok.

Speed dome camera moves out of control, sometimes which can
be controlled and sometimes can not control, there can not control
the upper and lower downtime, etc. Should not influence or
situation. Such questions may be in the wiring on the quality, if the
control signal produced a distortion or signal too weak, it will lead
to intelligent can not receive the ball to the correct control
commands. Control circuit wiring irregularities such as:
(a) Did not require the use of twisted pair, RS-485 requires the use
