Sorting out common problems of security monitoring system
Common problems of security monitoring system 1. What is the longest HDMI transmission distance? Answer: The longest HDMI transmission distance is generally 15 meters. 2. How to set up multiple video recorders in the same local area network remotely? Answer: The IP address of the video recorder needs to be set separately, and it is enough to configure the external network access for each video recorder separately. 3. How to use the dual network ports of the video recorder? Answer: The dual network ports can be set to multi-address settings or network fault tolerance mode. Network fault tolerance: two network cards use the same IP, you can choose the main network card by yourself. When the main network card has a problem, you can enable another network card. Multi-address setting: The NVR with two network ports can be set to multi-address setting under the 'Network Configuration-Basic Configuration-Network Mode' menu, so that you can set the IP addresses of different network segments for the two network ports. General application scenarios: One network port is connected to the camera, and the other network port is connected to the router connected to the external network; or one network port is connected to the IP address of one network segment, and the other network port is connected to the camera of another network segment. Please make a choice according to your own situation as to whether you want to use it. 4. Can one video recorder be connected to two displays? Answer, you can enter the main menu of the recorder-system configuration-preview configuration interface to set the image corresponding to the output port. 'HDMI/VGA' means that HMDI and VGA can be output at the same time, and the output picture is the same; if HDMI and VGA can be set separately, it means that the two video output ports can be connected to an external monitor at the same time, and the pictures can be different. The output screen of BNC can generally be set independently. If the recorder has two HMDI and two VGA output ports, it also supports simultaneous connection to the monitor output. 5. What should I do if the distance between the network video recorder and the camera is too far? Answer: If the distance between the camera and the video recorder is far, you can consider transmitting the network signal through an optical fiber transceiver. It is not recommended to cascade multiple switches for transmission. When the cascaded levels of switches are increased, data loss is prone to occur. 6. Can the files in the U disk be found and played on the video recorder? Answer: You can insert the U disk into the USB port of the recorder. In the main menu, playback interface, select external file playback. It is recommended that the U disk use FAT32 format. 7. Can the video recorder be connected to a wireless network? Answer: Video recorders generally do not support wireless connection routing. It needs to be connected to a router or switch through a network cable, or it is also possible to connect directly to the camera with a network cable. If the camera supports wireless, you can add the camera to the same network as the recorder, and then add the camera to the recorder. 8. The small screen of the video recorder is black. Double-click to zoom in to see it. Answer: Please enter the main menu of the video recorder-video configuration-encoding parameters, sub-stream interface, select the corresponding channel, and reduce the upper limit value of the sub-stream resolution. After adjustment, delete the camera and add it again. If the channel prompt does not support this function, you can log in to the camera to adjust it through the web page. In the configuration, video and audio interface, adjust the resolution of the sub-stream and the upper limit value of the stream. 9. What is the password in the video recorder editing IP channel? Answer: The password in the edit IP channel is the password of the camera. If it is a Hikvision camera, the password is the activation password set when it is used for the first time. 10. How to change the H.265 encoding to H.264? Answer: You can change the [Video Encoding] of the corresponding channel to H.264 in the main menu of the recorder-Recording Configuration-Encoding Parameters. If you don’t have a video recorder, you need to access the camera separately on the web page and modify the video and audio in the configuration interface. [Video encoding] is H.26411. Can non-POE devices connect to the POE switch? Answer: The POE switch will match the device before supplying power. The switch will only supply power to the device if the device complies with the POE power supply protocol. Therefore, devices that do not support POE power supply will not be damaged if they are connected to a POE switch.
