What are the functions of LAN monitoring software? Please explain in detail.

Real-time monitoring function: It can obtain the location of each terminal device in real time and record the maintenance status of the terminal. Terminal access control: It can realize access control to terminal requests and effectively manage the permissions of the local area network. Network performance monitoring: It can monitor the status and network traffic of network equipment, so as to optimize network performance.

Real-time screen monitoring Real-time monitoring of the current screen running screen of the terminal computer, which can display 16 terminal computer screen running images on a management terminal and display it at the same time in the form of a screen wall.

The software can automatically hide and monitor (not let the other party find out), so it can be used for LAN management and LAN monitoring. Main functions: Completely hidden operation: Completely hidden operation after the software is installed, including that the software cannot be found in the program of the control panel.

The first condition for an easy-to-use LAN monitoring software is that it has complete functionality and the system is stable and secure. For example, there are many functions of the domain shield.

Can the surveillance camera be directly connected to the 220-volt power supply?

1. No. Usually, Hikvision surveillance cameras need to be connected to a 12-volt DC power supply. If you really need to connect it to a 220-volt power supply, you need to use an adapter to convert the power supply to a 12-volt DC power supply.

2. Hello, the power supply of 220 volts can install surveillance cameras, but it cannot be used directly, because the installation of the cameraDirect current is required for use. You have to install a power adapter to convert 220-volt AC to 220-volt DC.

3. V AC will burn the monitoring equipment because its voltage is very high, and the working voltage of the monitoring equipment is generally below 12V. If 220V AC is connected to the monitoring equipment, it may cause a short circuit, failure or burn. Therefore, be careful not to connect 220V AC power to the monitoring device when using it.

4. Hikvision surveillance camera should be able to use 220V voltage directly. This should be able to get the operator, and the effect should be very good at this time.

cat can view the log dynamically

1, tail -f log file path is mainly used to view real-time log records, which is a dynamic record viewing. The cat log path is mainly used to view static historical logs, generally with the path name. The common this week type of logs are generally filtered by the required records with pipe symbols.

2. cat command: You can view the content of the whole file, which is suitable for viewing smaller log files. For example: bashCopy code cat /var/log/syslog This command will display all the contents of the /var/log/syslog file, which can be viewed directly on the terminal, but page turning and search are not supported.

3. Because we usually get very few logs with grep, we need to check the nearby logs.This is what I did. First of all: cat-ntest.log|grep terrain gets the line number of the key log.

4. You can also view the dynamic log. With the tail-f log file name, you can view all the new logs generated after typing the command in real time.

cat examination or something

Medical cat is a coronary artery examination method, which injects contrast agent into the vein, and then uses ct imaging to shoot, which can show whether the coronary artery is blocked and calcified foci, and can clearly locate .

Liver CAT refers to the use of computed tomography technology to check the lesions of the liver. CAT (Computed Axial Tomography), that is, computed tomography technology, is a commonly used technology in modern medical imaging.

ll is to view the information of directories, files, etc., such as users, group users, other users' reading, writing, execution permissions, creation time, file size, etc. The function of cat + file name is to display the specific content of the file on the terminal.

If there is a stranger staying in front of the door or someone posting a small advertisement in front of the door, Luke CatX can take a picture...

1. It can be taken. CatX7*24-hour monitoring of the dynamics in front of the door. When someone stays in front of the door ∞ Cat's eyes, it will start to record video. If it stays for a long time, it will send a notification to the user in time.

2. IfIf a stranger stays at the door for a long time, it will also trigger an alarm, because only those who have noted it can be identified by AI.

3. Recently purchased Luke CatX, no missing photos have been found so far. It is said that CatX's AI humanoid detection is quite powerful. It is equipped with a human body sensing sensor. If there is someone in front of the door, it can capture ∞ whether it is still or walking, and it can also filter out some useless warnings such as something blown by the wind.

4. If there is an abnormal situation such as someone staying outside the door, a notification will be sent to the mobile phone immediately, and the security defense line at the door of the house is very reassuring. At the same time, it can also intelligently filter useless warnings triggered by non-human beings and solve the problem of missed shooting in front of the door.

5. There is no need to worry about the problem of network disconnection at all. Even if the network is disconnected, it will not miss shooting ∞ leakage storage.Moreover, CatX also gives free cloud storage for 1 year and 7 days. The video dynamics within 7 days can be viewed in the cloud at any time. If you feel that there is something abnormal in front of the door, you can view and download the video recording at that time at any time.

6. Remote care at home, go out to work, or travel, if you are not at ease with your home, you can directly check the situation in front of the next house at any time through the intelligent cat eye remote video monitoring function.
