Whenever we use a monitor to view an image, we often encounter problems like image distortion, loss of input signals, or misalignment of lines and fields. These issues can be quite frustrating. So, what exactly causes them?
Firstly, since video frequencies span a broad range, video signals are highly prone to interference during transmission. This includes interference from 50Hz power sources or electromagnetic disruptions. Such interference can distort images, make them appear warped, create raceway effects, or cause lines and fields to fall out of sync. During the setup of any monitoring system, it’s crucial to keep video cables away from potential sources of electromagnetic interference.
Secondly, monitors follow industry standards where the professional input amplitude is typically set at 1Vp-P ±3dB (around 0.7Vp-P to 1.4Vp-P) with an input impedance of 75 ohms. If the input signal isn’t properly calibrated—due to factors like cable attenuation, impedance mismatches, or poorly connected BNC heads—the signal might drop below 0.7Vp-P or rise above 1.4Vp-P. This could happen if the camera outputs aren’t regulated correctly or if irregular devices are connected to the system (like signal distributors or amplifiers). In such cases, the image might become distorted or the line-field synchronization could fail, leading to poor viewing experiences.
Thirdly, differences in electrical potential between front-end devices, control hosts, and terminal equipment can also disrupt video signals. This often results in distorted images or visual artifacts resembling a racing track. If the entire system is powered on and the front-end and terminal devices are linked via a BNC connection, these disruptions may stem from differing ground potentials between the front and back-end equipment (essentially the shielding layers of the transmission cables). This potential difference can lead to serious interference, damaging components at the input end or leveling lines on the PCB. It can even cause the input to short-circuit, resulting in no image being displayed. Hence, when installing a monitoring system, it’s essential to adhere strictly to design specifications. Use copper grounding buses with adequate cross-sectional areas to ensure low resistance between the front and back ends.
Another common issue occurs when using a monitor as part of a matrix control system. Occasionally, when switching images, the matrix controller may briefly display a non-synced image. In surveillance systems, if there’s a phase discrepancy in the field sync signals from each front-end device (like cameras), the monitor will initially show a period of non-synchronized images upon switching channels. The greater the phase difference, the longer this period of non-synchronization lasts. To mitigate this, it's advisable to use front-end devices equipped with GEN-LOCK inputs during system installation. All front-end devices should rely on an external synchronization source, ensuring all image signals across different channels are controlled by the same synchronization signal, thus maintaining proper screen synchronization.
In conclusion, understanding these common problems and their solutions can help maintain optimal performance in your monitor systems. Whether dealing with interference, improper signal levels, or synchronization issues, careful planning and adherence to best practices are key to avoiding these pitfalls.
