I can't turn on the video camera. What's going on?
The reason why the video of the camera could not be turned on may be due to the following reasons: ** 1. Internet-related issues ** 1. **IP address setting ** - The IP address of the video recorder and the camera were not in the same network segment, so the video could not be opened. For the newly installed camera, before the adjustment, make sure that the video host IP and the camera IP are in the same network segment. You can modify the host IP in the video host main menu-System configuration-Network configuration-Basic configuration-IP V4 address. For the camera, you can use the intranet search tool to modify the camera IP address in batches and fill in the starting IP, port, intranet mask, gateway and other information. - If the Haikang video camera was added to the video recorder, it would indicate that the network could not be reached. It might be the wrong IP. You could edit the IP and change it to the same IP range as the video recorder before adding it. 2. ** Network transmission is not working ** - The transmission between the video recorder and the camera would also cause a situation where there was no video. 3. ** The camera resolution does not match the video recorder ** - When the camera resolution exceeds the maximum resolution supported by the video recorder, the video may not be displayed. For example, the Hikvision host may indicate that the image resources are insufficient. 4. ** Channel stream type not supported ** - When the video camera was in H.265 format and the video host was in H.264 format, the normal image could not be displayed. At this time, you need to access the camera on the intranet page. In the configuration, the coding parameters, and the recording parameters, change the video coding to H.264, save the application, and the recording host will delete the original channel and add a new camera. 5. ** Added third-party camera settings ** - Add the third-party manufacturer's camera that has not been set up properly and needs to be modified to the ONVII protocol, as well as the port information corresponding to the ONVII protocol to add equipment. ** 2. Equipment and hardware related issues ** 1. ** Power supply problem ** - The power supply of the network camera was insufficient, resulting in no output image. For example, the power of the switching power supply was insufficient, causing the switching power supply to be overheated and thermal protection. He could go to the scene to feel the temperature of the power supply. If it was cold, it meant that the power supply had crashed and needed to be replaced with a new power supply. 2. ** Circuit problem ** - During the construction, the wires were connected in the opposite direction, and the wires were too thin, resulting in a large pressure drop. The network camera could not be activated. During the construction, the operation must be standardized. The voltage and current input of the network camera can be measured with a universal meter. - The transmission line had a power supply. If the video transmission line was connected to an alternating current, it would cause the network camera head and the inside of the splitter to charge, thus blocking the video signal output. At this time, measure the voltage of the cable with a Multimeter, and then find the place where the power supply is connected or add an anti-interference device. 3. ** The camera itself malfunctioned ** - The internal program of the network camera crashed (mainly caused by a bad reset circuit), which could be restored by power failure and restart. - A loose camera cable, a damaged camera module, or a blocked lens could also cause the video to fail. You need to check whether the camera cable is secure and whether the lens is clean and unobstructed. If the problem still exists, it is recommended to contact professional maintenance personnel for maintenance or replacement of the camera module. ** 3. Software-related issues ** 1. ** System setup problem ** - The channel mode of the video recorder is wrong. For the video host that supports the connection of the simulation and the network camera, the channel mode needs to be modified. - If the video camera is added to the video recorder, it will prompt "User is locked/User name or password is wrong/Unknown error"(Take Haikang video camera as an example), you can delete the wrong channel and restart the video camera for 3 - 5 minutes. 2. ** Software Malfunction ** - The operating system is incompatible with the camera driver, the camera application has errors, or the system file is corrupted. This may cause the camera video to be unable to be opened. You can try to update the operating system and camera driver to the latest version, or re-install the camera application. At the same time, check if there is any other software that conflicts with the camera, such as security software or firewall. Try to temporarily shut down these software to see if it can solve the problem. 3. ** Authority and privacy settings ** - If the camera permission is turned off or the privacy settings prevent the use of the camera, you can enter the device settings to check the camera permission and privacy settings to ensure that the camera application has access to the camera.

Video camera
In photography, there was no such thing as a "camera". If one were to take it literally, it might be a camera that was held by one's hand during the filming process. There were many types of cameras, such as DSLR cameras, which were favored by professional photographers with high image quality and a wide range of lens options; Mirrorless cameras were light and high-performance, which were loved by photography enthusiasts; Film cameras had a unique texture and shooting experience; and smartphone cameras were convenient and instant, which were the main tools for public photography. When operating these cameras, it involved hand-held operations, such as controlling the exposure of the camera (the amount of light entering the camera was determined by the aperture, shutter speed, and Iso-sensitivity), choosing the appropriate lens (such as a wide-angle lens for scenery, a telephoto lens for distant objects), and using composition techniques (such as the rule of thirds, symmetrical composition, guide lines, etc.) to shoot the ideal work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
