First of all, we look at the SDI integrated camera and DVR through 485 control of the connection operation steps, in the process we will find where the problem is, it is also much easier to solve. (Go straight to the video)
SDI integrated camera
1. The camera is directly connected to the SDI display, and the control keyboard and DVR are connected through the 485 line.
A. The address code (ADDR) of the camera is 1 and the BAUD rate is 2400 can be seen in the upper right corner of the startup screen;
B. We can also see the baud rate of the control keyboard is 2400;
At this time, we can control the camera through the control keyboard (the baud rate of the camera and the control keyboard is 2400).
2. Then connect the video output of the camera to the DVR and open the DVR;
3. Set the display input format to HDMI (because the DVR output is HDMI format), and the screen will appear after setting;
4. Right click to bring up the pan head control interface. At this time, the function of multiplying is not available;
What’s the reason? How to solve it?
We first right click, select and open the main menu, under the system Settings, double click the pan head Settings, this time found that the baud rate is 9600 (and above we know that the baud rate of the camera is 2400, inconsistent). Therefore, here we need to change the baud rate of DVR to 2400, and then enter the control interface of the gimbal, we will find that we can control the camera to be doubled.
How to enter the camera setting menu in DVR?
On the PTZ control page, click the “Page Switch” button 3 times, and then click the “Enter Menu” button. At this time, the up and down left and right control keys are not available. In fact, we need to click the “page switch” button again, and you will find that the control keys are already available in the page.
