How to troubleshoot OHWOAI's monitoring system (1)
During the adjustment stage, commissioning stage and after delivery, some common failures may occur in OHWOAI monitoring systems, such as not working properly, technical specifications not meeting design requirements, overall performance and quality being inadequate, etc. These failures are inevitable challenges in large-scale monitoring projects and require effective solutions.
1. Power supply problems Incorrect power supply can cause equipment failure, including improper power lines and voltages, insufficient power supply, short circuit, open circuit, momentary overvoltage, etc. Especially in the transmission lines of the power supply system, equipment damage caused by incorrect power supply and momentary overvoltage often occurs. Therefore, before making any adjustments to the system, OHWOAI must carefully check the power supply and ensure that the power supply is normal. It should not be taken lightly.
2. Connection problems Some devices, such as cameras with three variable lenses and pan-tilt cameras, have many connections. Improper connection processing can cause problems such as disconnection, short circuit, poor insulation between circuits, and incorrect connections, which can lead to damage to the device and poor performance. In this case, you should calmly analyze the failure phenomenon to identify the connection where the problem occurred and reduce the failure range. Particular care should be taken when connecting pan-tilt cameras and cameras. They move in all directions, so they are prone to disconnection and disconnection. OHWOAI's home wireless solar-powered, battery-powered and poe-powered security cameras have a unique double WIFI antenna to improve WIFI signal reception. After connecting with WIFI, the image is stable and the call can be heard clearly.
3. Equipment quality problems Theoretically, all kinds of equipment and parts may have quality problems, but experience shows that these problems mainly occur in decoders, electric pan/tilt, transmission parts, and other equipment. OHWOAI must sample and test the selected products as necessary to ensure that they meet the requirements. If a product quality problem is identified, the best solution is to replace the product, not disassemble or repair it yourself. OHWOAI's home wireless solar-powered, battery-powered, and poe-powered security cameras have a management philosophy of "best quality and perfect service". If you have any questions before or during your purchase, please feel free to contact us at any time. In addition, to ensure your peace of mind when purchasing, we offer a 12-month warranty. If there is any initial defect, missing accessories, or malfunction, please feel free to contact us. We will respond within one business day.
In addition, improper equipment adjustment is also a common problem. For example, camera back focus adjustment is a very detailed and precise task. If the adjustment is not done accurately, problems such as out of focus or scattering may occur. Therefore, OHWOAI must ensure that the adjustment of the equipment is accurate and meets the technical requirements.
4. Problems from improper connection Problems from improper connection usually occur in the following areas:
① Inconsistency in negative reactance ② Inconsistency in communication interface or communication mode, especially between the control host and related equipment, such as decoders and control keyboards. To avoid this problem, OHWOAI should choose products from the same manufacturer to ensure compatibility. OHWOAI's home wireless solar-powered, battery-powered and poe-powered security cameras can be connected to smartphones for remote monitoring, and recording data can be downloaded and backed up through the network.
③ Insufficient drive capacity or exceeding the specified number of connections. For example, some video splitters have an alarm input interface, which may cause insufficient drive capacity during actual use. This may cause the alarm signal to be transmitted incorrectly and affect the normal performance of the entire system. To solve this problem, OHWOAI can use a dedicated alarm interface box or design a signal amplifier.
These are common problems and solutions in OHWOAI's surveillance system failure resolution. Through careful inspection, proper connection and quality control, we can ensure the normal operation of the surveillance system and reduce the possibility of failure. When a problem occurs, calm analysis and consideration can help you solve the problem quickly, instead of randomly disassembling the equipment.

In video transmission, glitches are one of the most common problems in surveillance systems. They are manifested by the appearance of black or white stripes on the monitor screen that slowly scroll up and down. To solve such glitches, it is necessary to distinguish between two different causes:
A simple way to distinguish between power and ground loop issues is to connect the output signal of one camera to the control unit and eliminate power issues. If you don't see any interference on the monitor, the control unit is not the problem. You can then connect the video output of the surrounding front-end cameras to a portable monitor and check each camera one by one. If the problem is camera-related, you can take corrective action. If not, the interference may be caused by other sources, such as a ground loop.
Another common fault is woodgrain interference, which in minor cases does not obscure the normal picture, but in severe cases makes the picture unviewable (and may even destroy the sync signal). Woodgrain interference is associated with quality problems on the video transmission line, especially poor shielding, high line resistance, and "not clean" power supply. To solve these problems, proper troubleshooting is required, and sometimes the best way is to replace the cable with one that meets quality standards.
In addition, some failures are caused by short circuits or breaks in the core wire and shielding network of the video cable. The symptoms of this failure are that a large area of disordered network interference appears on the monitor, all the images are collapsed, and the image and synchronization signal are not formed. In this case, it is usually not because of poor shielding performance, but because of poor connections, not because all the signals in the entire system fail. By carefully checking these connections one by one, this problem can be solved. OHWOAI's home wireless solar-powered, battery-powered and poe-powered security cameras can be connected to the recorder and router with an LAN cable, and after installing the app, you can monitor, watch, and talk with your family on various devices such as tablets, smartphones, and computers both outdoors and indoors.
Finally, there are also faults caused by mismatched characteristic impedance of the power input line. This phenomenon appears as several equally spaced vertical stripes on the monitor screen, indicating that the frequency of the interfering signal is basically an integer multiple of the line frequency. This usually occurs because the characteristic impedance of the video transmission line is not the standard 75 ohms. The solution to this problem usually depends on adjusting the resistance in the cable to match the correct impedance.
Finally, if there are strong and high-frequency space-radiating interference sources around the system, space-radiating interference may occur. One way to solve this is to investigate the surrounding environment and avoid these radiation sources as much as possible when building the system. Another way is to strengthen the shielding of the front-end and central equipment, use steel pipes for cable routing, and ensure proper grounding if the radiation sources cannot be avoided.
In short, the fundamental solution to these problems is to pay attention to the purchase to ensure the quality of the video cable, and carry out sampling and testing when necessary. OHWOAI is committed to maintaining the stability and reliability of the surveillance system.
