What is the function of the webcam?

Can be used for camera shooting and monitoring, such as shops or companies, communities and so on.

Network camera is a new generation camera which combines traditional camera and network technology. It can transmit images to the other side of the world through the network, and the remote browser does not need any professional software, as long as the standard web browser (such as "Microsoft"

IE or Netscape) can monitor its images. Network camera is generally composed of lens, image, sound sensor, A/D converter, image, sound, controller network server, external alarm, control interface and so on.

Webcam is also called IP.

Camera (IPC) consists of network coding module and analog camera. The network coding module encodes and compresses the analog video signals collected by the analog camera into digital signals for direct connection to network switching and routing equipment. The webcam has embedded chips and uses an embedded real-time operating system. Network camera is a new generation product which combines traditional camera and network video technology. The video signal transmitted by the camera is digitally compressed by an efficient compression chip and then transmitted to the Web server through the network bus. Users on the network can directly watch the camera image on the Web server through the browser, and authorized users can also control the action of the camera lens or the configuration of the operating system. Network cameras can realize monitoring more simply, especially remote monitoring, simpler construction and maintenance, better support for audio, better support for alarm linkage, more flexible video storage, richer product selection, higher-definition video effects and better monitoring management. In addition, IPC supports WIFI wireless access, 3G access, POE power supply (network power supply) and fiber access.

IP network camera is a digital device based on network transmission. The network camera not only has a common composite video signal output interface BNC, but also has a network output interface, which can directly connect the camera to the local LAN.

Network camera is an intelligent product with independent IP address and embedded operating system to realize network monitoring. It can be directly connected to the network through local area network, DSL connection or wireless network adapter. The network camera includes lens, filter, image sensor, digital compression controller and embedded operating system. The new webcam can also be equipped with other more advanced functions, such as dynamic monitoring. Simply put, it is a camera connected by a network cable. Pictures can be viewed on mobile phones or computers, and can also be monitored remotely.

What are the functions of the face recognition webcam?

The currently used face recognition cameras are basically 3D cameras, which mainly have the following functions:

1. 3D face reconstruction

Second, face detection.

Third, face contrast.

Fourth, face search.

Verb (abbreviation of verb) in vivo detection

It can also expand more functions, such as facial feature analysis, skin analysis, emotion recognition and so on.

What is a webcam?

Network camera, also known as IP camera, is a system that combines camera and computer. The main components of the network camera include lens, image sensor, one or more processors and memory. The processor is used for image processing, compression, video analysis and networking functions. The memory is used to store the firmware (computer program) of the network camera and support local video recording. Like computers, webcams also have their own IP addresses, which can be directly connected to the network and deployed anywhere in the network connection. Different from the network camera, this camera can only be used by connecting to a personal computer (PC) through USB or IEEE 1394 port, and the PC must be equipped with software. The network camera has the functions of web server, FTP (file transfer protocol) and email, and includes many other IP networks and security protocols. The webcam is directly connected to the network. The network camera can be configured to send video through an IP network, and can be used or authorized by users to watch and/or record on the spot according to predetermined time and activities. The collected images can be M-JPEG, MPEG-4 or H.264 video streams with different network protocols, or JPEG images uploaded by FTP, email or HTTP. For information, please visit: video compression formats and network protocols. In addition to capturing video, Axis network cameras also have event management and intelligent video functions, such as video motion detection, audio detection, damage alarm and automatic tracking. Most network cameras are also equipped with input/output (I/O) ports for connecting external devices such as sensors and repeaters. Other features include audio function and built-in power over Ethernet (PoE) support. Axis webcams also support advanced security and network management functions. The front and back of the webcam.

What are the functions of explosion-proof network cameras? These four functions must be understood.

Many friends think that the role of explosion-proof cameras is network scenes. In fact, in addition to the network function, he has several other interesting and practical functions. Let's see what it is.

As the most basic function of explosion-proof camera, the definition of image quality is often ignored by users. Nowadays, many businesses do not work hard on these basic and practical functions, but use some unnecessary fancy functions to divert users' attention and do not advocate them. In fact, when we choose an explosion-proof camera, we should also pay attention to the pixel number of the merchant's products. It is recommended to choose 3-megapixel and 4-megapixel explosion-proof network cameras when purchasing. The network scene is clear and the effect is good. Isn't it more cost-effective to choose higher pixels at the same price? Therefore, users must take the lead in considering video quality when choosing explosion-proof network cameras.

The main purpose of users' purchasing explosion-proof network cameras is to network in special occasions such as coal mines and underground mines, and the realization of this purpose cannot be separated from two practical functions: motion detection and real-time alarm. When the picture changes, for example, someone walks by, the system will automatically handle it and give an alarm. And push the alarm information to the user's mobile phone to help the owner find the danger in time and avoid property losses.

The cloud storage function of explosion-proof network camera can upload the automatically recorded 30-second alarm video to the cloud. When you don't pay attention to monitoring the situation there in time, just some criminals want to destroy the monitoring equipment, so don't worry at all. Allowing criminals to destroy criminal evidence in any way is equivalent to double insurance.

Even though the wide angle of most explosion-proof network cameras is above 100, it is still impossible to achieve 360 coverage without dead angle, and there are still security risks. Buhrer Li's 8 million-star panoramic splicing explosion-proof network camera supports panoramic shooting, with a large viewing angle, which can easily achieve 360 coverage of the whole house, eliminate all visual dead angles and upgrade the safety index again.

I checked in official website, buhrer, explosion-proof network cameras are suitable for mines, tunnels, energy, chemicals, petroleum, petrochemicals, gas stations, electric power, steel, construction sites, school laboratories, fireworks, ships, special vehicles, docks and islands. In other words, it can be used in any scene.
