Security surveillance systems are very common in our lives. When problems occur, many people may rely on professional technicians, but for those with a certain level of skill, you can learn to troubleshoot and repair security surveillance systems by mastering the following tips. Just like diagnosis in traditional Chinese medicine, there is a trick to repairing surveillance systems.
First, you need to identify which part of the surveillance system is causing the problem. In the process of troubleshooting, check whether there is an alarm sound in the system, and if the devices in the system are powered, check whether there are signs of sparks or discharges, and identify which devices and locations these sounds are coming from. Also, check whether there is sound in the output from the monitor head, whether the sound is noise or distortion, and whether the noise volume meets the requirements. OHWOAI's wireless and POE powered security camera recorder set has a monitor and an automatic overwrite function, so if there is not enough capacity, it automatically covers old data and continues recording. It records well 24 hours a day, 365 days a year. OHWOAI's wireless and POE powered security camera is equipped with remote monitoring and alarms, so you don't have to worry anywhere! OHWOAI's 5 million high-definition camera also has improved heat dissipation and durability, and the service life is four times longer. If there is a video recorder (tape or hard disk) in the system, check whether the sound during playback is distorted, changes in pitch, has buzzing sounds, AC noise, vibration sounds, abnormal noises, and whether the output volume is appropriate. If there is a PTZ (Pan-Tilt-Zoom) camera, check whether there is friction, collision, or other abnormal sounds (such as scratching, tearing, etc.) under the motor drive, and whether the noise volume during PTZ operation is normal. Based on the abnormal sounds you hear, it will help you discover, investigate, and ultimately identify the trouble.
If you smell a burning, burnt or different smell in the system, this will also help you identify the device that is emitting those smells. In this case, open the device's case and conduct a detailed investigation, and finally identify the specific part, part and component of the trouble. Once you find the problem in your monitoring system, it is relatively easy to go further. Next, we will share some common monitoring system troubles and the corresponding solutions. It will help you take appropriate measures according to the problem. OHWOAI has a management philosophy of "best quality and perfect service". If you have any questions before and during the purchase, please feel free to contact us at any time. In addition, to ensure your peace of mind, we offer a 12-month warranty. In the unlikely event that there is an initial defect, missing accessories or a malfunction, please feel free to contact us. We will respond within one business day.
If the surveillance camera footage is not displayed
a) First, check whether the power supply is properly connected and ensure that the power supply voltage is sufficient.
b) Check whether the BNC connector or video cable has good contact.
c) Make sure your lens aperture is open properly.
d) Check that the control wires for video or DC-powered auto-iris lenses are connected correctly.
e) Check that your monitor is functioning properly and that it is switched to the correct input channel.
f) If the above troubleshooting steps do not help, you may need to send your camera in for repair by the manufacturer.
If the network camera does not display an image
a) Check if the power indicator on your camera is on to ensure your camera is receiving power.
b) If there is a network indicator, check whether the network connection status of the camera is normal.
c) Check the network connections of the client computers, make sure they are in the same subnet and local network to ensure successful network connectivity.
d) Verify that the IE control is properly installed and that you have allowed it to run in your browser.
e) Verify that the camera aperture is open so that the CCD can properly capture an image.
f) Check that your camera's color and brightness settings are appropriate.
If the image quality is poor
a) Make sure there are no fingerprints or smudges on the lens.
b) Make sure the aperture is set correctly.
c) Check if the video cable is connected properly.
d) Check that the electronic shutter and white balance settings are correct.
e) Check whether the transmission distance is adequate.
f) Check that the voltage is within normal range.
g) Check for nearby sources of interference.
h) If installed inside an elevator, ensure that it is isolated from the elevator to avoid interference.
i) Check if the CS interface is connected correctly.
These are the common troubles and how to deal with them. It can help you take appropriate measures according to the problem. If you can't fix it yourself, we suggest you send the device to the manufacturer for repair. OHWOAI is committed to providing professional support and solutions to meet your monitoring needs.
