Frequently asked questions about network monitoring failure

Monitoring no networkThe video may be a network line problem, an unstable network environment, an IP camera setting problem, a hardware failure or a software problem. Network line problem IP camera uses IP network to transmit video. If there is a problem with the network line, the video will not be transmitted normally, resulting in the monitoring showing no network video.

The quality of the video transmission cable is not good, especially the shielding performance is poor (the shielding network is not a good quality copper wire network, or the shielding network is too thin to play a shielding role). At the same time, the wire resistance of this kind of video cable is too large, resulting in a large attenuation of the signal, which is also the reason for the aggravation of the fault.

Check whether there is a problem with the power supply of the surveillance camera. If it is an infrared surveillance camera, if you can see the red light at night, it means that the power supply is normal;If not, you can use a multimeter to measure the power supply and power supply lines.

There is a problem with the network you are in, so you can't access it. If there is a problem with the line connected to the monitor computer, check the line. There is a problem with the settings of the monitoring software. Check the IP settings of the software.

If the monitoring screen is all stuck, it is very likely to be caused by a problem with the trunk line or the poor performance of the core switch.

Reasons for monitoring offline: network connection problems, abnormal switching power supply, common hardware configuration failures. There is a problem with the network connection. The camera offline is most likely to be a problem with the network connection.

How to install a computer monitoring system?

1. Monitoring connection method: The camera is connected to a computer with a video capture card through a video cable.At present, the motherboard and configuration of the desktop computer support the connection of the camera. The video capture card hardware and the software matching the card must be installed on the computer motherboard in advance.

2. Open the browser and enter the official website of the high-definition monitoring system. Find options such as "Download" or "Product Download" on the website and click to enter the download page. On the download page, select the appropriate version to download according to your operating system. There are usually Windows and Mac versions to choose from.

3. Take the network digital monitoring system as an example, the installation of monitoring equipment requires cameras, video recorders, monitors or monitors, switches, routers, network cables, power cords, crystal heads, camera brackets and camera power supplies, etc.

Mobile phone remote monitoring and camera tutorial

Open the Fluorite Cloud Video, and then find the surveillance camera that you need to adjust the angle in the monitoring.Then click to enter the camera you need to adjust, and there is a column of icons at the bottom of the video. After clicking, the gimbal control will appear. In the gimbal control, we can move the camera up and down.

Gas pipeline network remote wireless monitoring system

Overview Gas pipeline network remote monitoring system is a computer-based production process control and scheduling automation system for on-site monitoring and automated management. Remote monitoring mainly uses RTU as the terminal. At present, there are many forms, such as using PSTN, laying special line radio stations, etc.

In the process of management, the oil and gas pipeline will use surveillance camera equipment for monitoring. In order to make good use of the surveillance camera equipment, the following operations need to be carried out: the appearance of the surveillance camera installed indoors will be disguised as some daily necessities.For example, robot ornaments, light bulbs or wall lamps.

Pressure isolation station: It is used for water supply enterprises to remotely monitor the water supply network. Staff can remotely monitor the pressure and flow of the city's water supply network in the water department dispatch center. Scientifically direct the start and stop of water supply equipment in various water plants to ensure the balance of water supply pressure and stable flow; timely detect and predict the occurrence of pipe burst accidents.

How to set up remote monitoring? It can be done in two steps

First, enter the IP of the router in the address bar of the browser to establish a connection. After logging in, set the LAN parameters and subnet mask, and the WAN login link. Then set the router to intranet address forwarding, which we usually use port 80. Then enter the domain name of Peanut Shell on the computer's software.

Then, in the [Select Remote User] section, enter the account name and password to allow remote access. Establish a remote desktop connection. On the monitored computer, click the Start menu, search for "remote desktop connection" or directly enter "mstsc", and you will see the [remote desktop connection] program and open it.

Step 2: Router port mapping Log in to the configuration interface of the router, find the virtual server/port mapping/forwarding rules, and perform the operation of mapping the port. A) The three ports of equipment 80, 8000 and 1554 are indispensable.

How to monitor the system Connect to the network

The video recorder and switch can connect the WAN port of the router to the external network cable and set up the network connection. The router and the monitoring switch are connected through the network cable, and the signal output line of the hard disk recorder can be connected to the signal input terminal of the monitoring switch. The camera of the video recorder is also connected to the switch, and the switch is connected to the router.

There is no network for monitoring. The connection method is as follows: the direct connection method connects the camera directly to the USB interface of the computer or mobile phone.Plug the USB interface of the camera into the USB interface of the computer or mobile phone to establish a physical connection. Turn on the device driver. The device driver allows the computer or mobile phone system to communicate with the camera.

The method of home monitoring and connecting the network is as follows: confirm that ADSL broadband has been opened and can be used normally. At the same time, install the router (such as TP-LINK) and set up the router according to the instructions to ensure that the Internet access mode is "automatic connection", and then check whether you can access the Internet normally through the computer.

How to monitor and connect to wifi: device connection, download APP, add device. Tools: Dandelion SD-WAN monitor, iphoneios7.
