What equipment is needed to set up a network video surveillance system

1. Camera camera (CAMERA or WEBCAM) Also known as computer camera, computer eye, electronic eye, etc., it is a kind of video input device widely used in video conferencing, telemedicine and real-time monitoring.Ordinary people can also communicate with each other with images and sounds on the Internet through the camera.

2. The following equipment is most basic to install the monitoring system: Camera: used to capture video images. Video recorder (NVR or DVR): used to record, store and manage video images captured by the camera. Network equipment: including network equipment such as switches or routers, which are used to connect and control various components of the monitoring system.

3. Monitor Monitor is a device used to display images and text. In home surveillance systems, monitors are usually used to display video images for real-time monitoring. Router A router is a device used for network connection. It can connect multiple networks and send packets to the target network according to certain rules.

4. Surveillance camera: Surveillance camera is the core part of the monitoring system. We need to choose different types of surveillance cameras according to the size and shape of the monitoring area. Video recorder: Video recorder is a device used to record surveillance images. We need to choose the storage capacity and recording mode of the video recorder.

5. To build a network video surveillance system, the following equipment is required: webcam; 2. Gather switch core switch network hard disk recorder platform server. If you need a splicing screen, you also need a high splicing controller.

6. Cameras, microphones, TV monitors or computer monitors, video recorders or digital video recorders are required to install surveillance. Camera: If you want to carry out video surveillance, you need to install a camera. The camera can be a webcam or an analog camera connected to a video recorder or TV.

large-scale factory installation network monitoring system

mm lens camera can scan about 70 degrees, 6mm You can only sweep 50 degrees like this. You can draw the angle radius by yourself and you will know by yourself. Four heads are definitely not enough. The wide-angle 10-head picture is fully connected, and the machine head equipped with four gimbals can sweep wherever you want.

Chemical plant monitoring installation requirements: The key to the chemical plant security monitoring scheme is whether the important areas, high-risk areas and sensitive areas are within the monitoring line of sight. The monitoring system will transmit the video surveillance of the factory entrance and exit and the employee workplace to the central management duty room in real time, and record and save the video data at the same time.

Yes, the same 1 is recommended to install the switch in the factory, in the middle of 25 cameras. Then the switch is connected to the office building with optical fiber. You need to buy a pair of photoelectric converters and a pair of optical fiber jumpers.

What parts does a network video surveillance system need

Network video surveillance components: network video surveillanceThe system is generally divided into three levels: front-end access, media exchange and user access, specifically composed of front-end coding unit, central business platform, network video unit, client unit and decoding unit.

[Answer]: The video surveillance system is generally composed of four main parts: the camera subsystem, the image transmission subsystem, the control subsystem and the display recording subsystem.

The monitoring system consists of four parts: front-end system, transmission system, control system and display storage system, and also has the functions of transmission, storage, processing and other functions of image signals.

To build a network video surveillance system, the following equipment is required: webcam; 2. Converge switch core switch network hard disk recorder platform server. If you need a splicing screen, you also need a high splicing controller.

How to connect the camera to the computer?

The network cable is made of crystal head and plugged into the tail network cable of the camera. The crystal head is also made at the other end of the network cable, which is plugged into the network port of the computer. Download the client software of a camera on the computer.

Prepare to install the camera supporting parts, pliers, screwdrivers, camera, camera charger, camera bracket, chassis, two BNC connectors, and connect the BNC cable. Pick up the camera bracket and install the chassis on the bracket. Install the camera on the bracket. Check whether the power supply is the matching power supply of the camera.

Bluetooth connection: Some cameras also support Bluetooth connection. You can turn on the Bluetooth function in the camera settings, and then search and connect the Bluetooth signal of the camera on the computer.It should be noted that when connecting the camera to the computer, you need to install the corresponding drivers and software first.

First, we connect the camera to the computer, connect the camera to the power supply, and then connect the camera to the computer with a network cable. Change the local connection to automatically obtain the IP address, and then change the IP address of the computer to the same network segment as the monitoring address.

Prepare the camera. Generally, the camera interface is a USB interface. Plug the camera into the USB port of the computer. After the camera is plugged into the computer, there will be a notification in the lower right corner of the computer taskbar. Click the notification to check the installation of the camera. Enter the device manager to check the hardware installation. Right-click the "My Computer" attribute on the desktop.

First of all, go to the official website of Hikvision to download and install the software for the computer client.Then connect the camera to the same network after plugging the camera into the power supply and controlling the computer, then open the software, select and click the [Add Device] button, as shown in the figure below.

Monitoring how to connect to the network

The method of home monitoring and connecting to 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.

First of all, plug in the Internet cable, go to the background of the wireless network camera, turn on the wireless function, and connect to the wireless router in your own home. Nowadays, wireless network cameras generally have P2P functions, and ordinary networks can be used for remote monitoring.Click to enter the "Looking" APP. After entering the software, find the add key in the upper right corner of the interface.

The camera is connected to the router with a network cable, and the computer is also connected to the same route and the client software is installed. Use the camera search tool to search for the camera IP and change the IP to save it in the same network segment as the router. After that, enter the camera IP in the IE bar and enter the WEB interface for simple settings.

Make sure that your monitoring device supports WiFi connection function. Usually, modern monitoring devices have built-in WiFi adapters. Turn on your monitoring device and enter its settings/configuration interface. You can use the device's built-in control panel, mobile phone application or computer software to set up.
