6.4 Control Failure
6.4.1 in ie, it can normally control the PTZ with 485 connection, but it cannot be controlled in
the software
Troubleshooting steps: please confirm that the correct protocol, address and baud rate have been
selected in the software;
Possible causes:
(1) Please confirm that the address setting in the software is correct;
(2) If easy7 software is used, ensure that "system settings -[ host] interface - Video Channel -
Equipment [address and protocol] content settings are correct";
(3) If there are still problems, please contact our after-sales technical personnel;
6.5 Video Failure
6.5.1 the software can connect the video normally, but the image is unstable, intermittent,
frame loss and other phenomena
Troubleshooting steps:
(1) Exit the software, check the CPU utilization of the machine, and eliminate the cause of
insufficient configuration of the machine itself or whether the host is poisoned;
(2) Ping the device to see if there is packet loss;
(3) Use the bandwidth test software to test the network bandwidth. If the bandwidth is
insufficient or unstable, please contact the network operator;
(4) When the network bandwidth is insufficient and the video fluency is guaranteed, we first
consider reducing the resolution of the image; in the case of not changing the resolution, in
the IE image quality setting, change to the variable bit rate mode, and increase the values of
the best quality and the worst quality in the image quality, so as to appropriately reduce the
video quality;
(5) Whether the system performance is insufficient due to too many functions being turned on,
such as character stacking, key area, intelligent analysis and other functions occupying the
performance, first turn off some functions and then verify whether the video is normal
