Reasons and solutions for the failure of the gimbal

[ Huaqiang Security Network News ] The use of the PTZ is now very popular. The PTZ will not work or will not rotate at all after use. It is a common failure of the PTZ. The emergence of this situation, in addition to the factors of product quality, is generally caused by the following reasons: 
(1) Only the gimbal that is installed in the camera is allowed to be hoisted during use. In this case, the hoisting method leads to an increase in the operating load of the gimbal, so that the use of the gimbal's rotating mechanism may be damaged or even burned out.
(2) The total weight of the camera and its protective cover exceeds the weight of the gimbal. Especially for the pan/tilt used outdoors, the weight of the protective cover is often too large, and the problem that the gimbal can not turn (especially in the vertical direction) often occurs.
(3) The outdoor cloud platform is faulty or even damaged due to excessive ambient temperature, low temperature, poor waterproofing and antifreeze measures.
2. When the distance is too far, the operation keyboard cannot remotely control the camera (including the lens) and the pan/tilt through the decoder.
This is mainly because when the distance is too far, the control signal is attenuated too much, and the control signal received by the decoder is too weak. At this time, a relay box should be added at a certain distance to amplify the shaping control signal.
3. The image contrast of the monitor is too small and the image is light.
This phenomenon is not a problem of controlling the main machine and the monitor itself, that is, the transmission distance is too far or the video transmission line is attenuated too much.
In this case, the line amplification and compensation device should be added.
4. The image clarity is not high, the details are lost, and the color signal is lost or the saturation is too small.
This is due to the excessive loss of the high frequency end of the image signal, which is caused by the substantial loss of the signal at frequencies above 3 mhz.
In this case, the transmission distance is too far, and there is no amplification compensation device in the middle; or because the distributed capacitance of the video transmission cable is too large; or because of the concentrated distribution of the equivalent capacitance between the core wire and the shield wire of the transmission line in the transmission link Caused.
5, color distortion.
This is a phenomenon that is prone to occur in long-distance video baseband transmission. The main reason is caused by the high phase shift of the signal caused by the transmission line. In this case, a phase compensator should be added.
6. The operating keyboard is out of order.
This phenomenon can basically be determined by operating the keyboard "dead" when checking the connection without problems. On the operation instructions of the keyboard, there is generally a way to solve the "dead". For example, "machine reset" can be solved by this method. If it can't be solved, it can be damaged by the keyboard itself.
7. The host does not clean the image.
The phenomenon of such a fault phenomenon is that on the screen after the selection, there is superimposed interference of other pictures, or interference of line sync signals of other images. This is because the quality of the host or matrix switch is not good enough to meet the isolation requirements of the image.
If the RF transmission system is used, it may also be caused by excessive modulation of the crosstalk modulation of the system.
